PCT No. PCT/SE96/00592 Sec. 371 Date Nov. 4, 1997 Sec. 102(e) Date Nov. 4, 1997 PCT Filed May 7, 1996 PCT Pub. No. WO96/35603 PCT Pub. Date Nov. 14, 1996The invention concerns an improved device in pallet loaders, comprising an upright frame (1) and a pair of horizontal lifting fork members (2) which may be raised and lowered together with said frame (1) by means of a lifting mechanism. The lifting fork members (2) are equipped at their outermost end with one support wheel (4) each, which wheels are attached to an articulated arm (14) arranged to be pivoted downwards. The frame (1) and the lifting fork members (2) may be raised and lowered by means of a rack (6) which is connected via a cable, wire on chain (10) to an articulated, two-armed rocker arm (13). In turn, the latter is connected to the articulated arm (14) by means of a traction rod (15) which is associated with the arm (14). Upon upwards motion of the rack (6) and thus of the frame (1) a pulling force on the cable (10) will be transferred via the rocker arm (13) and the traction rod (15) to the articulated arm (14), which then swings downwards, thus raising the lifting fork members (2).
