Levers 10, 12 for controlling the load-handling devices are carried so as to be able to pivot between two supports 18, 20. The levers 10, 12 are mounted on an off-centre part 24 of an adjusting shaft 22 which is caused to rotate by means of a wheel 54 in order to adjust the positions of the handles of the control levers. Between two adjustments, the wheel 54 is returned by a spring 68 into a position in which pins 62 are engaged in wedging holes 52. Use for facilitating adjustments, to stabilise the latter, and to make them simultaneous and identical for all the levers. <IMAGE> |
