ABSTRACT:
A winch, for example, for winding in and paying out a cable attached to a person in a hazardous situation, for example underground, comprises a pair of axles mounted on a frame, one of the axles carrying the cable drum for rotation therewith. Two safety brakes are provided, one on each axle, and each including a cam actuated clutch so that rotation of the drum in the pay-out direction is only allowed when the axles are driven in the pay-out direction. A handle for driving the axles includes two hand grasp portions for different mechanical advantage. The handle can be located at two different positions on a drive sprocket on one of the axles or on a second drive sprocket freely rotatable on the first axle for different drive ratios.
