Abstract

The positioning device has a hydraulic group (29) to move the frame in the required direction for the common translational motion of the forks (27). The hydraulic group includes two cylinders (30,31), each with a piston (32,33) separating an outer chamber (37,38) from an inner one (39,40). The pistons have piston rods (34,35) which are rigidly connected to each other, mechanically and hydraulically, in the direction of the upper crossbeam (12) of the frame. The connecting element can be brought to a fixed position relative to the truck.
