Abstract

The equipment is for use with winches having two or more drums accommodating wire ropes, particularly on tower cranes and cableways. A single motor reduction gear unit drives either through a pinion, and the drums are mounted on a rocking beam. Winding or unwinding of the cable forces the gear on one drum or the other into engagement with the pinion, while the other drum teeth simultaneously engage with a fixed gear sector automatically, in the event of locking pins not having already been inserted in it.
