Abstract

The truck has devices (1, 2) for the generation of a hydraulic pressure flow. The aforementioned devices include a hydraulic pump (2), which on its suction side communicates with a low-pressure accumulator (3). On its pressure side the hydraulic pump (2) communicates with a high-pressure accumulator (6). Devices for producing traversing and lifting/lowering movements are operatively connected to the aforementioned devices (1, 2) for generating the pressure flow. The aforementioned devices (12, 13, 15, 16) for producing a traversing movement include a hydraulic machine (12) acting as a pump/motor and capable of being regulated and of being reversed. The shaft (15) of this is operatively connected to the driving wheels (16) of the truck, and is connected between the suction and pressure sides of the hydraulic pump (2). A characterizing feature of the invention is that the aforementioned devices for producing lifting/lowering movements (4, 5, 7, 8, 10) include two hydraulic machines (4, 5) acting as a pump/motor, which are capable of being reversed and are operatively connected to one another via their shafts (17) in a previously disclosed manner. One of these (4), which is capable of being regulated, is connected between the suction and pressure sides of the pump (2). The other (5) is connected, on the one hand, to the pressure side of the pump (2) and, on the other hand, via a hydraulic pressure change-over device (10) communicating with the suction side of the pump (2), to a valve device (7) for actuating cylinder/piston units (8) for the aforementioned lifting/lowering movements.
