ABSTRACT:
An integrated winch and windlass for hauling in and paying out a mooring line which consists of wire rope serially connected to chain cable is described. The integrated system has a pair of traction winch drums for conveying the wire rope, and a chain wheel for conveying the chain cable. The chain wheel is coaxially mounted with one traction winch drum, and has a wire rope groove with a groove diameter substantially the same as that of the traction winch drums. A sheave directs wire rope between one of the drums and the chain wheel, and is so positioned that a wrap of wire rope is formed about the chain wheel whenever the system is operating on wire rope exclusively. A drive mechanism is provided for rotating the traction winch drums and chain wheel, including a common drive shaft, and a clutch mechanism which permits the traction winch drums and the chain wheel to be located simultaneously or separately. Simultaneous rotation of the chain wheel and traction winch drums is timed so that wire rope is conveyed at the same speed by the traction winch drums and the chain wheel. The chain wheel is effectively integrated into the traction winch functions, the wire rope groove of the chain wheel basically serving as the first groove of a traction winch.
