Abstract
A chain and cable handling winch system including a winch, a cable drum, a chain wheel, and a chain wheel lock assembly is provided. The chain wheel lock assembly releasable secures the chain wheel in a working position on a winch axle end. An interface body is mounted on the winch axle end such that it rotates with the axle. When the chain wheel is in its working position, slots and/or ribs of the chain wheel interlock with corresponding ribs and/or slots of the interface body, such that a torque load is transferred from the chain wheel to the winch axle via the interface body. The winch system further includes a chain wheel manipulator adapted to the exchange chain wheel mounted on the winch axle for another chain wheel.
