ABSTRACT:
A hydraulic hoist platform for passenger vehicles has floor group halves spaced from one another and a parallelogram device for each floor group half, movable up and down parallel to one another in a vertical plane and each comprising a carrier arm and a guide rod having a first end region articulated to its respective floor group half with bearing bodies highly loadable at least by torsion. The parallelogram devices have a second end region having a support device for the passenger vehicle. A lever device is secured rigidly to the outer region of each of the bearing bodies, and is angularly offset from the carrier arm in the direction of lifting. A hydraulic unit is arranged substantially horizontally in each of the floor groups, and is connected between the lever device and the floor groups.
