Fork-lift truck arrangement with frame 18 on which a fork wagon 30 is mounted to move vertically and on which vertical hydraulic mechanisms 22, 23 are fixed. The fork wagon is moved by means of chains 10, 11 or cables which are laid round chain or cable wheels 24, 25 on the hydraulics' piston rods 31, 32 and one end of which 26, 27 is connected to the frame 18. The chains 10, 11 or cables have their other ends connected to both the fork wagon 30 and to each other, so that a force directed upwards in one chain would result in a downwards force in the other, whereby jamming of the fork wagon on the frame caused by oblique loading would be counteracted. <IMAGE> |
