Winch device for controlled unwind of e.g. anchor lines used to assist hoisting or lowering of sails on boat

摘要

The winch drum (3) has a shell (12) surrounding part of its radial periphery and the band (13) or line is fed through the gap between the drum and shell so that when the drum is rotated the band or line is wound double around the drum. The crank and handle (5, 7) used to rotate the drum can be locked into position.
