The present invention relates to a compensating method applicable to vehicles having a lifting device made up of a mast (4) and vertically adjustable load carrier (5) provided on the mast. The method is for compensating departures in the position of loads (8, 9), preferably goods on loading stools or pallets, on the load carrier (5) relative to a frame (2) of a wheel driver vehicle (1). Loads (8, 9) of different weight when lifted to various heights deflect the mast (4) outwards in various degrees from an unloaded position. The vehicle (1) is adapted to repeatedly deliver loads (8, 9) on the load carrier (5) at different levels (12, 13, 14) in a storage system (11) and in predetermined delivering positions (P3) on each such level (12, 13, 14). A drive-up length (Lo) corresponding to moving the vehicle (1) without a load (8, 9) from a reference point (R2) to a delivering position (P2) has been determined. In order to provide quick and safe compensation of deflections, the invention determines the size ( DELTA 1) of the outward deflection of the mast (4) is and the vehicle (1) is operated to move from the reference point (R2) towards the delivering position (P2) by length (Llast) corresponding to the determined drive-up length (Lo) reduced by a partial length ( DELTA 1) which depends on the outward deflection of the mast (4). |
