ISO CONTAINER

Technical field

This invention relates to an ISO container.

An ISO (International Organization for Standardization) container is a container having standard specifications which render it suitable for transportation (for example, by suitably equipped ship, aeroplane, train or truck). ISO containers of this type are designed to facilitate the transportation of objects even over great distances, between a loading site and a destination site, where the ISO containers are unloaded. In other cases, they may be kept at an active site for housing people, machinery and equipment on site for a predetermined period of time.

Background art

Examples of ISO containers are described in patent documents US2009/01841 12A1 and EP1945538B1 . In contrast, an example of specific fastening elements for the ISO containers is described in document US9248957B2.

ISO containers have standardised fastening elements for each corner of the ISO container, which facilitate its transportation and logistics. Once they have reached the destination site, such ISO containers are usually moved using movement systems such as cranes, straddle carriers and lifting platforms. Said movement systems are very bulky, have very long assembly and disassembly times and relatively high costs. In some types of transportation, the destination site may not be very accessible (impracticable terrain), dangerous for people (for geopolitical, natural or environmental reasons), impossible (or too expensive) to assemble a crane or movement systems on, because of the excessive dimensions or difficulties transferring the components. Moreover, the use of such movement systems increases the degree of risk for the operators, therefore, the safety measures necessary. Disclosure of the invention

The aim of this invention is to provide an ISO container which overcomes the above-mentioned disadvantages of the prior art.

Said aim is fulfilled by the ISO container according to this invention, characterized as described in the appended claims.

In particular, the aim of this invention is to provide an ISO container which is particularly easy to move.

A first aspect of this description relates to an ISO container for transporting objects between a loading site and a destination site. It should be noticed that said ISO container is an ISO container suitable for being transported by ship or other means of transport, in the standard way.

In one possible embodiment, the ISO container comprises a containment structure which comprises four side walls, a top wall and a bottom wall. In one embodiment at least one wall of said ISO container is openable to allow the loading and unloading of goods. Said containment structure of the ISO container, being a parallelepiped, has eight corners, defined by the common point between three walls, and twelve edges, defined by the common segment between two walls. It should be noticed that the containment structure may be made of various materials, including steel, aluminium and composite materials (for example, carbon fibre or other materials). In one embodiment, the containers are stackable.

According to one aspect of the following description, said containment structure of the ISO container defines an internal volume, in which, in addition to the components described below, a space can be assigned for transporting objects.

Said containment structure has horizontal symmetry, relative to a longitudinal axis, belonging to a plane parallel to the plane containing the top wall or the bottom wall, and equidistant from two opposite first side walls. Said internal volume has a second horizontal symmetry, relative to a transversal axis, belonging to a plane parallel to the plane containing the top wall or the bottom wall, and equidistant from two opposite second side walls. Said internal volume has a vertical symmetry, relative to a vertical axis, perpendicular to the longitudinal axis and to the transversal axis. Operatively, the functioning of the ISO container allows the definition of two working directions: a vertical direction, perpendicular to the top wall and parallel to the vertical axis of symmetry of the containment structure, and a longitudinal direction, the direction of ISO container advancing along the ground, substantially perpendicular to the vertical direction. In one embodiment, said vertical direction coincides with the vertical axis of symmetry. In one embodiment, said longitudinal direction coincides with the longitudinal axis of symmetry or with the transversal axis of symmetry. According to one aspect of the following description, said ISO container comprises a plurality of fastening elements to allow its transportation by means of a movement system. In a preferred embodiment, said fastening elements are positioned in the corners of said containment structure. In another embodiment, said fastening elements are positioned at the edges or inside the surface defined by each wall of the containment structure. In one embodiment, said fastening elements have at least one hole, made on the surface belonging to one of the walls of the containment structure. Said fastening elements allow the ISO container to comply with ISO standards and therefore to be moved by means of the movement systems, such as cranes.

In one possible embodiment, said internal volume comprises a power generating system. In one embodiment, said power generator is a mechanical power generator. Said mechanical power generator is connected to a conversion unit for the production of electricity. In another possible embodiment, said power generator is an electricity generator. That power generator allows the ISO container to have programmable autonomy and therefore to be able to operate autonomously remotely.

In one embodiment, said internal volume comprises a control unit programmed according to a control logic able to manage the functioning and interactions between components of the internal volume. In one embodiment, said control unit is connected to a user interface included inside the internal volume. In another possible embodiment, said control unit is connected to a remote user interface by means of a wireless or radio frequency connection. That wireless connection allows operation of the functions of said ISO container from a position of safety, increasing safety for personnel involved.

In one embodiment, said internal volume comprises a propulsion unit. In one embodiment, the propulsion unit is an undercarriage or a plurality of undercarriages.

In one embodiment, said propulsion unit is connected to the power generator with an actuator, provided with a motion transmission system if necessary. Said actuator is constituted of two portions. The first fixed portion is attached to the containment structure, whilst the second movable portion is attached to at least one component of the propulsion unit.

In one embodiment, said ISO container is self-propelled due to the presence of said propulsion unit and has two types of movement.

The first movement, which we shall call "raising", is for moving the movable part of the actuator relative to the containment structure, therefore for moving the interface element of the propulsion unit relative to the containment structure along the vertical direction. That movement is driven by the power generator attached to the containment structure of the ISO container. The second movement, which we shall call "advancing", allows the entire ISO container to be moved along the ground in the longitudinal direction.

The propulsion unit comprises at least one ground interface element for interfacing with the ground. In one possible embodiment, the propulsion unit is attached to the internal volume of the ISO container and the interface with the ground is constantly in the external position relative to said internal volume, so as to interface with the ground before said containment structure. In another, preferred, embodiment, said interface element is attached to the movable portion of the actuator and has two operating configurations.

In a first operating configuration the propulsion unit is completely contained inside the internal volume.

In a second operating configuration the propulsion unit is at least partly outside said internal volume. In one possible embodiment, in the second operating configuration, the propulsion unit is outside the internal volume, by a variable portion which contains at least the interface element. By varying the portion outside the internal volume, this allows adjustment of the height of the containment structure itself relative to the ground, to avoid obstacles, during the ISO container advancing step.

According to one aspect of this description, this invention intends to protect an ISO container comprising:

- a containment structure which includes a bottom wall, a top wall and four side walls connected to each other to define an internal volume, a vertical direction, perpendicular to the top wall and to the bottom wall, and a plurality of corners on the containment structure itself;

In at least one operating position of the vehicle, along the transit path, at least one part of the vehicle is surrounded by the container, that is to say, is contained in the container. That facilitates monitoring of it (or sanitising, or other operations to be performed on the vehicle by means of instruments contained in the container and operatively active on the vehicle (or part of it) disposed in the operating position.

In one embodiment, the container comprises an entrance door, disposed on one of the side walls, and an exit door, disposed on a side wall opposite the one which comprises the entrance door, both movable between a pass-through position, where the entrance door and the exit door are open to define the through passage, and a transporting position, where the entrance door and the exit door are closed on the respective side wall.

In one embodiment, the monitoring structure includes a portion of the containment structure of the ISO container. In this case, the transit zone is inside the ISO container and it is defined by the through passage.

In one embodiment, the monitoring structure includes an articulated structure. The articulated structure is movable between a transport configuration and a working configuration. In one embodiment, in the transport configuration, the articulated structure is contained in the internal volume of the container. In other embodiments, the articulated structure is rigidly connected the containment structure in a recover position. In transport configuration, the articulated structure is retracted to occupy the less possible space.

In one embodiment, the ISO container comprises a top door. In one embodiment, the top door is placed on the top wall of the ISO container. In one embodiment, the ISO container includes a recovering space. The recovering space, in one embodiment, is inside the internal volume of the ISO container. In one embodiment, the recovering space is partially outside the internal volume of the ISO container and is defined by a recovering box.

In one embodiment, in the transport configuration, the articulated structure is placed in the recovering space, closed by the top door.

In one embodiment, in the working configuration, the articulated structure is at least partially outside the internal volume of the ISO container. In the working configuration, the articulated structure is extended to define the monitoring structure. IN the working position, the articulated structure is resting on the ground in at least a support. In the working configuration, the articulated structure reaches a height higher than the height of the containment structure of the ISO container. This allows the ISO container to monitor vehicles which have a height higher than the maximum height of the ISO container according to the ISO standard.

In one embodiment, in the working configuration, the articulated structure is outgoing from the recovering space that is accessible through the opened top door.

In one embodiment, the articulated structure includes a first arm. In one embodiment, the articulated structure includes a second arm. In one embodiment, the articulated structure includes a third arm.

The first arm is connected to the containment structure of the ISO container (or it is connected to a support element, joined to the containment structure of the ISO container). The first arm is connected to the recovering space from which the articulated structure is extracted. The first arm is movable with respect to the containment structure of the

ISO container. In one embodiment, the first arm is outgoing from the top wall of the ISO container when the articulated structure is in working configuration.

In one embodiment, the first arm is rotatable around an axis parallel to the vertical direction. In one embodiment, the first arm is rotatable around an extraction axis, included in a plane defined by the transversal direction and the longitudinal direction. In one embodiment the extraction axis is parallel to the longitudinal direction.

In this way, the first arm can vary his inclination with respect to the top wall of the container. In fact, according to one aspect of the present description, the first arm is configured to rotate around the extraction axis to modify his inclination with respect to the top wall of the container till reaching the working configuration, in which the first arm is substantially perpendicular to the top wall of the container.

In one embodiment, the first arm slides with respect to the containment structure along the vertical direction.

In one embodiment, the first arm is connected to the second arm with an articulated connection.

In one embodiment, the second arm, in working configuration, is extended along a transversal direction. In one embodiment, the second arm, in working configuration, is extended in the longitudinal direction.

In one embodiment, the third arm is connected to the second arm. The third arm is configured to incline itself with respect to the second arm by a connection hinge. In one embodiment, the third arm is folded on the second arm in the transport configuration for reducing the space occupied. In one embodiment, the third arm is oriented along a vertical direction in the working configuration.

In one embodiment, the third arm is resting on the ground.

The height of the third arm defines the maximum height of the vehicle that the ISO container is able to scan. The third arm comprises a support element. In one embodiment, the third arm includes a plurality of support elements.

In one embodiment, the support element is adjustable with respect to the third arm. This allows to vary the length of the third arm as a function of the ground condition.

In one embodiment, the articulated structure is provided with a plurality of monitoring devices of the monitoring system.

In one embodiment, the ISO container includes a movable weight scale or a plurality of movable weight scales. In one embodiment, the movable weight scale comprises four (or more than four) measurement daises. The measurement daises are placed in the transit zone when it is needed to detect the weight of a vehicle. Each measurement dais is configured to receive a respective wheel of the vehicle and to measure the portion of the weight loaded on it.

In one embodiment, the recovering space has a "L" shape. In one embodiment, in the working configuration, the articulated structure defines a monitoring arc.

In one possible embodiment, said propulsion unit (or undercarriage) has a motor (propulsor) for advancing the ISO container. In one embodiment, said propulsion unit has a propulsor for advancing the ISO container. In another possible embodiment, in contrast, the advancing is assigned to the power generator contained in the containment structure of the ISO container. In one embodiment, the motor and the power generator operate in conjunction with each other depending on the torque required for advancing.

In one embodiment the propulsion unit also comprises a motion transmission system configured to transmit the torque from the motor to the ground interface element.

In a preferred embodiment, said interface with the ground is at least one caterpillar track. That solution allows advancing even on ground with low adherence and high deformability. Said caterpillar tracks, distributing the shape on a wider surface, reduce the pressure on the ground and allow travelling even along ground that is not compact. The teeth of the caterpillar track increase the grip on the ground, allowing functioning even with low adherence.

In another embodiment, the interface element is a wheel with a tyre. That solution allows the weight of the ISO container to be reduced and can be suitable for less adverse external conditions.

Said propulsion unit is movable along the vertical direction, from the first operating configuration to the second operating configuration, and vice versa.

In one possible embodiment, during the shifting, the propulsion unit passes through the bottom wall. In one possible embodiment, said bottom wall comprises an opening. In one possible embodiment, said opening is automatic, whilst in another embodiment it is manual. This opening is variable between the fully closed position, in which there is no through gap between the internal volume of the ISO container and the external environment, and the fully open position, in which the area of a through gap is at least equal to the surface area on which the propulsion unit rests on the bottom wall. In the fully closed position said opening guarantees that the ISO container is impermeable to weather and foreign bodies.

In one embodiment, said opening is automatically controlled by the control unit, which also manages the simultaneous shifting of the propulsion unit. During transportation of the ISO container using the movement systems, in the fully closed position said opening allows the prevention of entry of unwanted material. Moreover, it allows a reduction in the stress on a suspension point of the propulsion unit, resting part of the weight of the self-same propulsion unit on it. In another embodiment, said opening is semi-automatic, that is to say, it requires at least the presence of a worker for supervision or direct action on the opening procedure.

According to one aspect of the following description, the ISO container comprises a system of sensors. The system of sensors has at least one proximity sensor and/or one optical sensor. Said system of sensors is connected to the control unit and dialogues with the control logic to manage, depending on the data collected, the functioning of the components of said internal volume.

In one embodiment said ISO container comprises at least one connector, connected to the fastening element of the ISO container, to allow connection of the ISO container to a containment module. Said connector is configured to be integrated not just with the fastening element which includes it, but also with the fastening element of the containment module. Said connector may be integrated with the fastening element of the ISO container permanently or temporarily. Said connector may be integrated with the fastening element of the ISO container automatically or manually. The connector integration methods allow considerable versatility in the use of the ISO container.

In one embodiment, said ISO container comprises at least one locking/unlocking unit, connected to the connector, for constraining said connector with the fastening element with which it is integrated. In one embodiment, in order to perform its function, said locking/unlocking unit is interposed between said at least one connector and the fastening element of the containment module. In another embodiment, in order to perform its function, said locking/unlocking unit is interposed between said at least one connector and the fastening element of the ISO container. In a further embodiment, said locking/unlocking unit is configured to be interposed between said at least one connector and both of the fastening elements of the ISO container and of the containment module.

In one embodiment, said interposing of the locking/unlocking unit is manual. In contrast, in another embodiment, said interposing of the locking/unlocking unit is automatic.

In one embodiment, said locking/unlocking unit is constituted of a single element. In one embodiment, said locking/unlocking unit is constituted of two or more elements, although they are attached to each other.

Another aim of this description is to provide a modular ISO container system which overcomes the above-mentioned disadvantages of the prior art.

In one embodiment, said modular container system comprises a containment module. In one embodiment, the containment module is an ISO container, with or without a propulsion unit. In another embodiment, said module is any module with the capacity for connection to the ISO container equipped with a propulsion unit. In one embodiment, said modular container system comprises at least one propulsion module which is an ISO container equipped with a propulsion unit. In a preferred embodiment the modular container system comprises at least two propulsion modules positioned on two opposite walls of the containment module. This allows the transporting and moving of a plurality of containment modules, in the zone limited to the destination site, with the use of only two propulsion modules.

The modular container system is characterized by two operating configurations. A "static" first operating configuration, where the modular container is resting on the ground with the bottom walls of the respective modules. In that first operating configuration, the fastening procedure between the modules of the modular container system is performed. That fastening procedure comprises use of the connector and of the locking unit.

A "dynamic" second operating configuration, where the respective containment structures of the modules of the modular container system are raised relative to the ground and where contact with the ground is reserved for the interface elements of the propulsion units of the propulsion modules. In that second operating configuration, advancing of the containment module attached to the propulsion modules is performed, along the longitudinal direction.

Another aim of this description is to provide a method for moving an object.

In one embodiment, said method comprises a first preparation step, with the movement systems such as a crane, of an ISO container, equipped with a propulsion unit for its advancing along the ground. Such movement systems interface with said ISO container by means of the fastening elements. The above-mentioned preparation is performed with the propulsion unit in the first operating configuration and with said opening on the bottom wall in the fully closed position.

That method comprises a second step in which the object to be transported is coupled to the ISO container. In one embodiment, said coupling is a housing inside the internal volume of the ISO container. In another embodiment said coupling is a locking of the object on the containment structure by means of locking straps or ropes or hinges.

That method comprises a third step in which the propulsion unit switches from the first operating configuration to the second operating configuration. In one embodiment, a consequence of this switching is operation of the opening on the bottom wall as far as the fully open position. That switching occurs by means of shifting of the propulsion unit of the propulsion module along the vertical direction. In one embodiment, said vertical direction coincides with the vertical axis of symmetry to optimise ISO container balancing.

Said method comprises a fourth step of activation of the propulsion unit for transporting the object associated with the ISO container. In one embodiment, said activation of the propulsion unit occurs with a motor attached to the interface element of the propulsion unit. In another embodiment, said activation occurs with the power generator contained in the containment structure of the ISO container.

In one embodiment of the modular container system, in which said system also comprises a plurality of fastening elements, a plurality of connectors and a plurality of locking elements, said method for moving an object allows the transporting of a containment module, outside the internal volume of the ISO container according to this description. In one embodiment of the modular container system, said containment module is an ISO container, with or without the propulsion unit.

Said method comprises a first step of preparation on the ground, with the movement systems, of two ISO containers, both equipped with a propulsion unit. Said preparation is performed with the propulsion units in the first operating configuration and with said openings on the respective bottom walls closed.

That method comprises a second step in which the propulsion units switch from the first operating configuration to the second operating configuration by means of remote operation of the actuators housed in the respective internal volumes of the ISO containers. Said switching consists of shifting of said propulsion units along the vertical direction. In said second step, by activating the propulsion unit, one first propulsion module advances and moves close to a wall of the containment module, whilst the other advances and moves close to an opposite wall of the same containment module.

That advancing is performed after activation of the proximity and optical sensors, whether it is performed remotely or from a local position contained in the containment structure of the ISO container.

That method comprises a third step of preparing the propulsion modules in the fastening configuration, that is to say, with the sensors activated and the connectors configured for coupling to the fastening elements of the containment module. In that fastening configuration a further movement close to the containment module is performed, which allows a fastening position to be reached. In one variant of the method, said movement of the two propulsion modules towards the containment module can occur simultaneously. In contrast, in another variant, said movements towards the containment module may occur separately.

Said method comprises a fourth step in which the propulsion units switch from the second operating configuration to the first operating configuration by means of remote operation of the actuators housed in the respective internal volumes of the ISO containers. In that step, a lateral fastening procedure on the short side is performed. In one variant of the method, said fastening procedure is a lateral fastening procedure on the long side. In another variant of the method, the fastening procedure may be performed either on the short side or on the long side. Said lateral fastening procedure between the propulsion modules and the containment modules comprises manual or automatic operation of a set of fastening elements, connectors and locking elements, in such a way as to attach the modules along the vertical direction of raising and the longitudinal direction of advancing. Manual operation of said connectors and locking elements allows the system to be kept flexible and not very complex in terms of automation. On the other hand, this type of operation assumes that operators are present at the place of attachment of the containment module. Therefore, where conditions are difficult, or at sites that are hard for people to access, it is preferable to have an automatic fastening system.

Such locking elements allow the prevention of misalignment of the modules along the vertical direction of raising and the longitudinal direction of advancing. In one variant of the method, the two propulsion modules may be managed in a synchronised way by the processors, so that the movements along the vertical direction of raising and the longitudinal direction of advancing are equal and synchronised. That synchronised management allows greater safety and reduced stress on the locking elements. In a further variant of the method, the synchronisation of the movements allows the locking elements to be taken away.

Said method comprises a fifth step of final switching of the propulsion units from the first operating configuration to the second operating configuration by means of remote operation of the actuators housed in the respective internal volumes of the ISO containers. That switching is another shift along the vertical direction.

This later step also comprises advancing of the propulsion modules and therefore transporting of the containment module, attached to them, in the area limited to the destination site. Said transporting solves the problem of the need to suspend the ISO container at a height which involves risks for workers and surrounding objects, as well as allowing movement in spaces with a very limited volume.

According to an aspect of the present description, the document also provides a method for monitoring vehicle passing through the ISO container.

In one embodiment, the method comprises a step of providing a monitoring system. The method comprises a step of monitoring, in which the monitoring system performs a check on objects passing along a transit path that passes through the ISO container.

In one embodiment, the method comprises a step reconfiguration of the ISO container.

In one embodiment, in said step of reconfiguration, an entrance door, placed on one of the side walls, and an exit door, placed on a side wall opposite to the side wall in which is placed the entrance door, move from passage position, in which the entrance door and the exit door are open to define a through passage, and a transport position, in which the entrance door and the exit door are closed on the respective side wall.

In said embodiment, the transit path is individuated by the objects passing from the entrance door to the exit door along the through passage.

In one embodiment, in said step of reconfiguration, an articulated structure, connected to the containment structure of the ISO container, moves from a transport configuration, in which the articulated structure is folded and housed (at least in part) in the internal volume of the ISO container, to a working configuration, in which the articulated structure is extended until it gets in touch with the ground. In said step of reconfiguration, the articulated structure defines a monitoring arc (or portal), under which it is possible to identify the transit path.

In one embodiment, the step of reconfiguration comprises a step of extraction. In the step of extraction, a first arm of the articulated structure is extracted. In one embodiment, the first arm rotates around an axis parallel to the longitudinal direction by a hinge from a rest position to a working position.

In one embodiment, the step of reconfiguration comprises a step of rotation. In the step of rotation, a second arm of the articulated structure rotates around an axis of main development of the first arm for falling out from the ISO container.

In one embodiment, the step of reconfiguration comprises a step of distension. In the step of distension, a third arm of the articulated structure rotates with respect to the second arm to vary the mutual inclination between the respective axis of main development of the third and the second arm. In the step of distension, the third arm rotates between a rest position, in which the respective axis of main development of the third and the second arm are inclined of zero degrees (or 180 degrees), and a working position, in which the respective axis of main development of the third and the second arm are perpendicular to each other.

In one embodiment, in the step of reconfiguration, the articulated structure moves from the working configuration to the transport configuration.

Hence, according to another aspect, the present description provides a self-moving ISO container, provided with a handling system that allows it to move, for handling objects contained therein, or for picking and moving other containers.

A second "movable" portion 504B is, in contrast, movable relative to the containment structure 2 and is attached to the ground interface element 301 of the propulsion unit 3. In another embodiment, said movable portion 504B is movable relative to the containment structure 2 and is attached to the propulsion unit 3 as a whole. Due to its constraint to the propulsion unit 3, said movable part 504B of the actuator 504 will be able to vary its position relative to the containment structure 2, so that, in the first operating configuration of the propulsion unit 3 it is completely contained inside the internal volume 5 and, in the second operating configuration of the propulsion unit 3, it is partly outside said internal volume 5.

In one embodiment, the movable part 504B of the actuator 504 also comprises a shock absorbing system (not illustrated) for the ISO container motion at least along the vertical direction 207'. In one embodiment, said shock absorbing system is of the mechanical type and comprises a spring with coils, whilst in another embodiment said shock absorbing system is of the hydraulic type and comprises a cylinder and piston unit. In one embodiment, the cylinder and piston unit is self-levelling by means of a suitable controller.

In one embodiment, the actuator 504 is a cylinder and piston unit, in which the cylinder is the fixed part 504A and the piston is the movable part 504B of the actuator 504. In another embodiment, the actuator 504 is a toothed slide - rack system, in which the toothed slide is the movable part 504B and the rack is the fixed part 504A.

In one embodiment, the bottom wall 201 of the ISO container 1 comprises an opening 202.

In one embodiment, said opening 202 allows the propulsion unit 3 to pass from the first operating configuration to the second operating configuration, remaining open during the ISO container 1 advancing.

In one possible embodiment, not illustrated in this invention, the opening 202 in the bottom wall 201 is of the bellows-seal or diaphragm type. Said bellows seal is composed of panels which are constrained to each other by a hinge. Said hinge is integrated with a return leaf spring which, in the closed position, keeps the elements of the bellows seal in the same plane corresponding to the bottom wall.

In one embodiment, the bellows seal is opened using the power generator

503 which, with at least one intermediate element, transmits the motion as far as the bellows seal return belt.

In one embodiment, the propulsion unit 3 comprises a motor 302 attached to the propulsion unit 3 itself. Said motor 302, in one embodiment, is an internal combustion engine equipped with a transmission system 303 for transmitting the motion from the motor 302 to the ground interface element 301 (said ground interface element 301 could be included in or defined by the undercarriage). In one embodiment, said motor 302 is an electric motor powered by a power cable from the power generator 503 attached to the containment structure 2.

In contrast, in one possible embodiment, the propulsion unit 3 does not comprise a motor 302. The caterpillar tracks are activated by the power generator 503, attached to the containment structure 2, by means of a second transmission system 508 designed to keep one part attached to the power generator 503, therefore to the containment structure 2, and another part attached to the propulsion unit 3. In one possible embodiment, said second transmission system 508 comprises the coupling, by means of a splined profile, of two concentric driving shafts. Said second transmission system 508 therefore allows a shifting along the vertical direction 207', but while maintaining the torque transmission and the speed supplied by the power generator 503.

In one embodiment, illustrated in the figures, the ISO container 1 comprises at least two propulsion units 3. In that embodiment, each propulsion unit 3 comprises the respective actuator 504 including a fixed portion 504A and a movable portion 504B. In one embodiment, the propulsion units 3, in the first operating configuration, are disposed inside the internal volume 5 of the ISO container 1 inside suitable storage zones 1 A. In one embodiment, said storage zones 1 A comprise an inspection cover 1 B. The inspection cover 1 B is hinged to the containment structure 2. The inspection cover 1 B has an open configuration, during maintenance or inspection of the respective propulsion unit 3 of the ISO container 1 . The inspection cover 1 B has a closed configuration, during movement or transporting of the ISO container 1 . In one embodiment, the ISO container 1 comprises a hydraulic power generator 509. The hydraulic power generator 509 powers the actuator 504 of each cylinder and allows sliding of the movable portion 504B and with it the interface element 301 of the respective propulsion unit 3. In one embodiment, the ISO container 1 comprises one or more supporting columns 510, disposed inside the internal volume 5 of the containment structure 2.

In one embodiment, the two propulsion units 3 are completely independent and adjusted with the control unit 501 by means of dedicated controllers.

The independence of the propulsion units 3 allows the ISO container 1 to be rotated while keeping one propulsion unit 3 stationary and operating the other propulsion unit 3. In one embodiment, the actuators 504 of each propulsion unit 3 are self-levelling.

In one embodiment, the suspension point 208 is made on the supporting column 510.

The containment structure 2 also comprises a plurality of fastening elements 401 . In a preferred embodiment, said fastening elements 401 are positioned at least on the corners 210 of the ISO container 1 . In another embodiment, said fastening elements 401 are located depending on the dimensions of the object to be fastened, always guaranteeing the ISO container 1 the possibility of being transported by the lifting means 8 for interacting with the fastening elements 401 located on the corners. In one embodiment, the fastening elements 401 are integrated with a connector 403.

In one embodiment, said connectors 403 are operatively positioned on the plates 402' of the fastening elements 401 belonging to the side walls 204. In one embodiment, said connectors are operatively extending from at least one side wall 204. In another preferred embodiment, said connectors 403 are operatively positioned on each plate 402' of the fastening elements 401 belonging to the side wall 204 in contact with a module to be transported. Moreover, said connectors 403 operatively extend from the side wall 204 in contact with a module to be transported.

In one embodiment, the fastening elements 401 and the connectors 403 are integrated with locking/unlocking elements 404 of the movements along the vertical direction 207' and along the longitudinal direction.

The figures show the second operating configuration, where the propulsion unit 3 is partly outside the internal volume 5 of the containment structure 2 of the ISO container 1 .

In one possible embodiment, illustrated in the figures, the connector 403 is permanently integrated with the fastening element 401 and, therefore, cannot be disconnected from the containment structure 2. By way of example and without limiting the scope of the invention, the connector 403, with cylindrical shape, is constrained to the fastening element 401 by means of a prismatic joint which allows it to slide only along an axis parallel to the longitudinal axis 205 (axis of symmetry of the connector 403 itself) and prevents it from rotating relative to an axis orthogonal to its axis of symmetry. The end of the connector 403 furthest from the vertical axis of symmetry 207 of the ISO container 1 comprises a through hole 403' which extends orthogonally to the self-same axis of symmetry of the connector 403.

The connector 403, as described, defines two operating configurations. A first "retracted" operating configuration, where said connector 403 is completely contained inside the internal volume 5 of the containment structure 2.

A second "extended" operating configuration, where said connector 403 is partly outside the containment structure 2 and extending from a side wall 204, ready to make contact with the object to be transported.

In a position close to a containment module 601 to be transported, the control unit 501 controlled by the software 502, activates sliding of the connector 403 from the retracted position to the extended position.

The connector 403 is integrated with a locking element 404. In one embodiment, said locking element 404 comprises a pin 404', with axis of symmetry parallel to the vertical direction 207', positioned in the hole 402' of the fastening element 401 on the top wall 201 of the containment module 601 to be transported, and intercepting the hole 403' of the connector 403 of the propulsion module 602.

In one variant said locking element 404 is inserted manually. In another variant said locking element 404 is inserted automatically.

In another possible embodiment, illustrated in the figures, the connector 403 is temporarily integrated with the fastening element 401 and, therefore, can be removed from the latter at the end of transporting of the containment module 601 . By way of example and without limiting the scope of the invention, the connector 403, with cylindrical shape, comprises two through holes 403' which are positioned at its two ends.

The connector 403, as described, defines two operating configurations. A first "retracted" operating configuration, where said connector 403 is completely contained inside the internal volume 5 of the containment structure 2 but released and not in contact with the fastening element 401 of the ISO container 1 .

A second "extended" operating configuration, where said connector 403 is positioned in the hole 402" of the plate 402' on the fastening element 401 and extending from the side wall 204 of the containment structure 2, ready to make contact with the containment module 601 .

Switching between the retracted position and the extended position occurs manually.

The connector 403 is, therefore, integrated with a locking element 404. In one embodiment, said locking element comprises two pins 404', with axis of symmetry parallel to the vertical axis 207, and a rod 404" connected to the two pins 404', with axis of symmetry parallel to the longitudinal axis 205, constituting a substantially "C"-shaped rigid body. Said locking element 404 will be positioned in such a way that the pins 404' simultaneously intercept the holes 402" of the fastening elements 401 on the top walls 203 of the containment module 601 to be to be transported and of the ISO container 1 , and the holes 403' at the ends of the connector 403. In one possible embodiment, said locking element 404 is inserted manually.

The ISO container 1 also comprises a set of sensors for monitoring the environment inside and outside the container.

In one embodiment, the set of sensors for monitoring the internal environment, not illustrated in the figures, comprise one or more of the following sensors:

- a temperature sensor, for monitoring any overheating of the auxiliary units of the propulsion unit,

- a pressure sensor, for monitoring the maintenance of a slight overpressure, where necessary, so as to prevent the entry of hazardous fumes or gases,

5 - a weight sensor, for evaluating the remaining loading capacity.

The sensors included inside the internal volume 5, which relate to the propulsion unit of the container, comprise, by way of example and without limiting the scope of the invention, one or more of the following sensors:

- speed sensor,

o - torque transmitted sensor,

- position sensor, for the position of the propulsion unit 3 relative to the containment structure 2,

- fuel level sensor,

- sensor for monitoring suspensions (hydraulic pressure in hydraulic5 suspensions, elastic force in mechanical suspensions),

- sensor for lubricating oil and cooling temperature,

- GPS,

- sound sensor,

- light sensor,

o - security sensor connected to a rapid response security system,

- obstacle proximity volumetric sensors.

Amongst the sensors for monitoring the external environment, in one embodiment, the ISO container 1 comprises at least one optical sensor 406. In one embodiment, the ISO container comprises at least one 5 proximity sensor 405. In one embodiment, said proximity sensor 405 is a laser beam whose reflection time is identified, for then deducing the distance from the first body struck. In one embodiment, said optical sensor 406 is an infra-red video camera able to rotate on a field of view with a solid angle of 2 ττ, that is to say, 360° monitoring relative to the plane 0 containing the side wall 204, ready for contact with the containment module 601 , on which the optical sensor 406 is positioned. In one embodiment, the set of sensors for monitoring the external environment comprise one or more of the following sensors:

- a temperature sensor,

- an atmospheric pressure sensor,

- a sound sensor,

- an altitude sensor, relative to the ground and relative to sea level,

- a strain gauge for assessing any deformations of the side wall 204,

- an anemometer for assessing the wind speed

- a gyroscope for assessing the inclination of the side wall relative to the geocentric vertical.

With reference to the accompanying figures, the numeral 6 denotes a modular container system comprising a containment module 601 and a propulsion module 602. In another embodiment, illustrated in the figures, said modular container system 6 comprises a containment module 601 and two propulsion modules 602.

In one embodiment, the containment module 601 is an ISO container 1 , with or without a propulsion unit 3 prepared for transporting objects or housing operators. In another embodiment, the containment module 601 is any module able to transport objects that has fastening elements 401 compatible with the propulsion modules 602. In one embodiment, said propulsion modules 602 are two ISO containers 1 equipped with respective propulsion units 3. Said modular container system 6 also comprises a plurality of connectors 403, permanent or temporary, and of locking elements 404. The modular container system 6 has two operating configurations.

A first "released" operating configuration, where the three modules (601 , 602', 602") are divided from each other but are prepared for coupling. In this configuration the connectors 403 are retracted and the locking elements 404 are not yet inserted.

In the released configuration, the respective propulsion units 3 of the propulsion modules 602 are in the first operating configuration, with the interface element 301 contained inside the internal volume 5.

A second "constrained" operating configuration, where the three modules are coupled and constrained to each other in such a way as to prevent relative movements between the three modules along the vertical direction 207' and the longitudinal direction. In the constrained configuration, the respective propulsion units 3 of the propulsion modules 602 are in the second operating configuration, ready to transport the containment module 601 , the connectors 403 are in the extended position and the fastening elements 404 are inserted in the suitable seats.

In one possible embodiment, the modular container system 6 may comprise a single propulsion module 602. In one embodiment, the containment module 601 is provided with only one fastening wall, whilst the opposite wall is characterized by a working tool interfaced with the ground. By way of example but without limiting the scope of the invention, the containment module is a plough and the propulsion module is an ISO container 1 which acts as the tractor along agricultural land (embodiment not illustrated), or along tunnels or beaches with sandstone ground that is not firm.

In one embodiment, which comprises the modular container system 6, as described above, a method is provided for transporting a generic containment module 601 , provided that it is capable of connecting to the propulsion modules 602.

That method presupposes the following operating steps, illustrated in Figures 10A, 10B, 10C, 10D, 10E, 10F.

A first step of preparing the propulsion modules 602 on the ground, using the movement systems 8, such as, by way of example only, cranes, lifting platforms or overhead travelling cranes. During this first step, the opening 202 on the bottom wall 201 is in the closed position and the connectors 403 are not yet in the extended position.

Said method then comprises a second step of switching the propulsion units 3 to the second operating configuration, then moving the propulsion modules 602 close to the containment module 601 respectively at each of the two opposite side walls 204" prepared for contact with the propulsion modules 602. During this step, the connectors 403 are still in the retracted position.

That method comprises the further step of switching the operating configuration of the propulsion unit 3 from the second operating configuration to the first operating configuration for rendering uniform the height of the modules and allowing the fastenings. Said step also comprises preparing the connectors 403 in the extended position in such a way as to intercept the fastening elements 401 of the containment module 601 .

In one variant of the method, said connectors 403 are inserted manually. In another variant of the method, said connectors 403 are, in contrast, inserted automatically.

Said step also comprises fastening of the containment module 601 by the propulsion modules 602 and positioning of the locking elements 404. In one variant of the method, said locking elements 404 are inserted manually. In another variant of the method, said locking elements 404 are, in contrast, inserted automatically. In a further variant, said locking elements 404 are not inserted.

The fourth step of said method comprises switching the propulsion units 3, preferably in a synchronised way, from the first operating configuration to the second operating configuration. During that step, the containment module 601 is definitively constrained to the two propulsion modules 602 The fifth and final step of said method comprises transporting the containment module 601 attached to the two propulsion modules 602. In one variant of the method, the leading propulsion module 602', which precedes all of the modules in the direction of movement, is the driven module, whilst the trailing propulsion module 602" is the driving module. In one variant of the method, the leading propulsion module 602' is the driving module, whilst the trailing propulsion module 602" is the driven module.

In one variant of the method, the leading propulsion module 602' and the trailing propulsion module 602" are both driving modules.

Moreover, in one variant of the method, the respective control units 501 of the leading 602' and trailing 602" propulsion modules dialogue in such a way as to synchronise the movements of the two propulsion modules along the vertical direction 207' of raising and the longitudinal direction of advancing, to prevent stresses on the connectors 403 and the locking elements 404 during advancing and transporting of the containment module 601 .According to an aspect of the description, the present document also provides a method for monitoring vehicle passing through the ISO container.

In one embodiment, the method comprises a step of providing a monitoring system. The method comprises a monitoring step, in which the monitoring system performs controls and measurements on objects passing on a transit path that passes through the ISO container 1 .

In one embodiment, the method comprises a reconfiguration step of the ISO container.

In one embodiment, in said reconfiguration step, an entrance door 9A, located on one of the side walls 204, and an exit door 9B, located in a side wall 204 opposite to the side wall 204 comprising the entrance door 9A, are moving between a passage position, in which the entrance door 9A and the exit door 9B are open to define a through passage, and a transport position, in which the entrance door 9A and the exit door 9B are closed on the respective side wall 204. In such embodiment, the transit path id identified by the objects passing from the entrance door 9A to the exit door 9B along the through passage.

In one embodiment, the reconfiguration step comprises a step of extraction of an entrance ramp 90A. In one embodiment, the reconfiguration step comprises a step of extraction of an exit ramp 90B.

In one embodiment, in the reconfiguration step, an articulated structure 7, connected to the containment structure 2 of the ISO container 1 , is moving from a transport configuration C1 , in which the articulated structure 7 is folded and (at least partially) contained into the internal volume of the container 1 , to a working configuration C2, in which the articulated structure 7 is extended until it gets in touch with the ground. In said reconfiguration step, the articulated structure 7 defines a monitoring arc 7', under which it is possible to identify the transit path.

In one embodiment, the reconfiguration step includes a step of extraction

F1 . In the extraction step, a first arm 701 of the articulated structure 7 is extracted. In one embodiment, the first arm 701 rotates around an extraction axis E, parallel to the longitudinal direction 205 by means of a hinge 701 ' from a rest position to a working position.

In one embodiment, the reconfiguration step includes a step of rotation F2.

In the step of rotation F2, a second arm 702 of the articulated structure 7 rotates with respect to an axis of main development A1 of the first arm 701 to extend outside from the ISO container 1 .

In one embodiment, the reconfiguration step includes a distension step F3. In the step of distension F3, a third arm 703 of the articulated structure 7 rotates with respect to the second arm 702 to vary the mutual inclination between the respective axis of main development. In the step of distension F3, the third arm 703 rotates from a rest position, in which the axis of main development of the third 703 and second 702 arm are inclined of zero degrees (or 180 degrees), to a working position, in which the axis of main development of the third 703 and the second 702 arm are perpendicular to each other.

In one embodiment, in the reconfiguration step, the articulated structure 7 is moving from the working configuration C2 to the transport configuration C1 . In one embodiment, the method comprises a step of reconfiguration control. In the step of reconfiguration control, a control unit 501 sends command signals to an actuator 704 of the articulated structure 7 to drive the articulated structure 7 in its movement from the transport configuration C1 to the working configuration C2.

It should be noted that it is also expected that the container 1 includes a first and a second articulated structure 7, each of those being movable between the transport configuration C1 and the working configuration C2, to define two different transit paths. In this way, it is possible to manage contemporaneously the transit of the vehicles in both travelling directions of.

The first and the second articulated structure 7 can be extractable in opposite parts of the container 1 to define respective arcs located in planes oriented perpendicularly to the longitudinal direction 205, or perpendicularly to the transversal direction 206, according to the embodiment.

In one embodiment, the container can define three or four parallel transit paths, oriented along a transversal direction, through correspondent passages: two passages are defined by the first and the second articulated structure 7 and one or two further passages are defined by correspondent internal passages, located inside the container 1 .

It is also expected that inside the container 1 it is present a control room 901 , containing equipment and working stations for operators involved in the monitoring operations. In one embodiment, the control room 901 is interposed between two different passages defined inside the container.
