The inventive portable concrete plant (1) comprises at least one conveyor stand (9) which is located on the other end of the conveyor (2) and contacts with the ground when one end of the conveyor (2) is connected with the mixer (4) on the carrier chassis (7). In a preferred embodiment, the conveyor stand (9) is connected to the conveyor (2) by means of a detachable or foldable structure.

In a preferred embodiment of the invention, there is a mixer (4) at one end of the conveyor (2) and a conveyor leg (9) at the other end thereof. In a preferred embodiment, the conveyor (2) extends outwards from the chassis (7) and the extending part thereof is fixed with the conveyor leg (9). The part of the conveyor (2) extending outwards from the frame (7) is connected to the chassis (7) by means of a joint configuration. Thus, it is ensured that the conveyor (2) occupies less volume by folding towards the frame (7) during the transportation. In the inventive portable concrete plant (1), the scale group (3) comprises three separate weighing elements whereby preferably the water, cement and additives to be mixed in the mixer (4) are weighed. At the bottom of the scale group (3), the mixer (4) wherein the water, cement and additives weighed by means of the weighing elements are mixed with the aggregate.

In the inventive portable concrete plant (1), the mixer (4) mixes the aggregate conveyed by means of the conveyor (2) and the concrete content conveyed from the scale group (4), prepares the concrete and comprises a discharge outlet for pouring the prepared concrete.

The platform (5) surrounds both the scale group (3) and the mixer (4). The platform (5) is connected to the part it surrounds by means of a demountable connection. Thus, it can be detached when it is desired to be carried by means of a container.
