Abstract:
The invention relates to a chain and cable handling winch system (1) comprising a winch, a cable drum (3), a chain wheel (4), and a chain wheel lock assembly (6). The chain wheel lock assembly releasably secures the chain wheel in a working position on a winch axle end (2). In an embodiment, 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 (8) of the interface body, such that a torque load is transferred from the chain wheel to the winch axle via the interface body. In an alternative embodiment the winch system comprises a chain wheel manipulator (54) adapted to the exchange chain wheel mounted on the winch axle for another chain wheel.
Abstract:
A chain and cable handling winch system comprising of a winch, the winch having a winch axle, the winch axle having a winch axle end adapted to mount a chain wheel thereon in a working position a cable drum mounted on the winch axle a frame, supporting the winch axle such that the winch axle is supported on opposite sides of the cable drum by a first and second support, the first support being located inbetween the cable drum and the chain wheel end of the winch axle; and a motor drive adapted to drive the winch a chain wheel, the chain wheel having a chain wheel body with a central opening adapted to engage the chain wheel end of the winch axle, the chain wheel being in a working position when mounted on the chain wheel end of the winch axle a chain wheel lock assembly, wherein the assembly is adapted to releasably secure the chain wheel in the working position on the chain wheel end of the winch axle, the chain wheel lock assembly comprising one or more locking members movable between a locking position and an unlocking position; and a chain wheel manipulator adapted to the exchange the chain wheel mounted on the chain wheel end of the winch axle for another chain wheel, the chain wheel manipulator having a chain wheel support adapted to support a chain wheel, the chain wheel support being positionable in a chain wheel exchange position adjacent to the chain wheel end of the winch axle to mount a chain wheel onto the winch axle end and to dismount the chain wheel from the winch axle end.
