ABSTRACT:
The invention pertains to a loading platform for a truck. Said platform is carried by the truck by a set of levers actuated by at least one hydraulic jack. A further hydraulic cylinder acts on said levers, said cylinder having a first and a second chamber, respectively containing a first and a second piston. The rod of the first piston extends into the second chamber while the rod of the second piston is pivotably connected to the platform. The cross-sectional surface of said first piston is larger than that of said jack, while the cross-sectional surface of the second piston is larger than that of the rod of the first piston but smaller than that of the latter.
