By means of the proposed invention, an extremely simple arrangement is achieved for obtaining level-adjusting movements in a vehicle (11), by means of which goods (44) are to be transported in a goods-handling system. The propulsion 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 transverse shaft (25) and an associated driving motor (38), that affects the rotational 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 wheels are mounted eccentrically by means of bearing sleeves (27, 28) that are arranged 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 adjustments. The arrangement can also be made easily adjustable. During the lifting action, the front and rear ends (11a), lib can move sequentially, so that one end is raised first and thereafter the second end, or vice versa. A rocking lifting movement is thus obtained in relation to an adjacent pallet, goods (47) or other surface, which rocking movement results in an improved releasing function in relation to the adjacent pallets, goods, etc. |
