Drive device for manual driving of a capstan

摘要

An arrangement for manually driving a winch (1) or like rotatable device, comprising an input rotational shaft (2) which is actuable for driving the rotational device and arranged to rotate an external drum (3) or the like at a given transmission ratio, the arrangement comprising a preferably peg-like drive part (4) which co-acts rotationally with the input shaft without mutual rotation therebetween and further comprises a crank arm (5) or the like intended for co-action with the drive part such as to produce a rotational movement. The arrangement is particularly characterized by devices (12) which transmit rotational movement of the crank arm (5) to the drive part (4) at a given transmission ratio.
