The vehicle (1) comprises a frame (2) with four identical wheels (3), each provided with a motor (4). The rear wheels are connected with a steering facility (5). The vehicle is driven by an internal combustion engine (6), which drives a hydraulic pump unit (7), which feeds the wheel motors (4) and a further hydraulic system. On the front side of the vehicle rails (8a,8b) are virtually vertically fixed and two other rails (9a,9b) can be pushed into them, which on the upper side are provided with gearwheels (10a,10b), over which steel cables or chains (11a,11b) run, which on one side are fixed to a carriage (12) and on the other side to the frame (2). Between the two sets of rails are two hydraulic cylinders (13a,13b), with which the gearwheels and thus the carriage can be moved. Hinged around a hinge axis (14) a coupling plate (15) is fixed to the carriage. In order to couple an object (17) to the coupling plate an intermediate plate (18) is used connected with the object. The upper edge of the coupling plate can be simply hooked into an upper edge of the intermediate plate, after which the carriage can be moved upwards until the intermediate plate connects against the coupling plate. The intermediate plate is then secured via apertures in the coupling plate and corresponding openings in the intermediate plate with the aid of two hydraulically operating bolts (19a,19b).
