By means of the proposed invention, an extremely simple arrangement is ac hieved for obtaining level-adjusting movements in a vehicle (11), by means o f which goods (44) are to be transported in a goods -handling system. The pr opulsion of the vehicle is handled by a drive shaft (3) and a driving motor (7) connected to this. The level adjustment is handled by an additional tran sverse shaft (25) and an associated driving motor (38), that affects the rot ational positions of the drive shaft and the rear pair of wheels (29, 30) or sets of wheels. The drive shaft and the rear pair of wheels or sets of whee ls are mounted eccentrically by means of bearing sleeves (27, 28) that are a rranged in such a way that they can rotate. If required, the vehicle can be set to produce different sizes of the lifting movements or the level adjustm ents. The arrangement can also be made easily adjustable. During the lifting action, the front and rear ends (11a), lib can move sequentially, so that o ne end is raised first and thereafter the second end, or vice versa. A rocki ng lifting movement is thus obtained in relation to an adjacent pallet, good s (47) or other surface, which rocking movement results in an improved relea sing function in relation to the adjacent pallets, goods, etc.
