The object of the invention is a trolley, equipped with a manual jack screw, designed for transporting, loading and unloading of goods.

Known solutions trolleys, are powered by electric motors or combustion. These trucks need extensive journeys accordingly to be able to move. In addition, the engine needs to have air circulation in order to discharge gases produced by their movement. These trucks also require power to move (charging current or refuel). These trucks have a relatively large size making it impossible to move them in all conditions.

Trolley invention solves the problem of having to supply motor vehicle used for transporting goods. It is lightweight and compact. The truck needs a little space to be able to travel from point to point. Durable screw mechanism, operated by the user, used when lifting truck cargo space allows the transport of goods weighing up to 100kg. The invention relates to a new design using a hand truck worm mechanism. A transport trolley is composed of a metal frame and has four wheels arranged at two parallel facing rails which are provided a mast for lifting the floor (platform) truck with a manual mechanism of the worm. The platform is secured to the mast by means of guides. Screw mechanism has a steel cable and lock that prevents the backflow of links. At the top of the mast is the block in which are mounted a link.

The truck is shown closer to the accompanying drawings, in which Figure 1 shows a cart in a top view, Figure 2 the truck in side view, Figure 3 truck rear view of the truck Figure 4 is a perspective view, Figure 5 a fragment of the truck magnification.

A transport trolley according to the invention comprises a chassis / 2 /, the wheels / 1 /, the mast / 3 /, the lifter / 5 / based on the worm gear with the lock / 8 / and the loading floor I I.

A transport trolley has a steel frame and four wheels / 1 /, which are situated in two parallel facing rails / 2 /, which is the mast / 3 /, for lifting the floor (platform) / 4 / bogie by means of a manual a worm mechanism / 5 /. Flatbed / 4 / is fixed to the mast / 4 / through the guides / 6 /. The mechanism of auger 1 5 1 has steel cable / 7 /, and lock / 8 /, which prevents the backflow of links / 7 /. At the top of the mast / 3 / is a block / 9 / on which is mounted link / 7 /. Carriage chassis comprises two parallel rails / 2 / in the form of U-profiles, connected to the transverse reinforcement elements / 10 /. At both ends of the both rails are mounted wheels / 1 /, with one of the pairs is rotatably mounted, making it easier maneuverability. Both rotary wheels are equipped with locking mechanisms (brakes) to prevent uncontrolled movement of the wheelchair. On the chassis / 2 /, the end of the rotating wheels mounted mast / 3 / in the form of two channel sections connected to the top of the mast the transverse stabilizing element / 11 /. This location rotary wheel, the operator side, facilitates maneuverability. In both parallel elements / 12 / mast / 3 / are mounted guides / 6 /, which moves the loading / 4 /. The mast is attached also a mechanism for elevating / 5 /, the loading / 4 / and handles / 13 /, to move and maneuver the truck. The lifting mechanism is comprised of a steel cord 1 1 1 and the mechanism of the worm / 5 /, which through movement of crank / 15 / link / 7 / is wound onto the drum / 14 /. The drum is fitted around toothed ratchet / 8 /, preventing accidental release of the rope 111 and, consequently, falling loading platform / 4 /.
