Abstract
A winch mechanism that is capable of sustained, heavy load operation comprises a frame, a ratchet, and a pawl for cooperative engagement with a pinion and a drum gear. The frame includes a plurality of apertures positioned proximate to the pawl axle, one aperture for each mode of operation of the winch mechanism. Pawl position relative to the pinion is defined by the position of a ratchet plug and the apertures in the frame. The winch mechanism includes a forward-engaged mode, a reverse-engaged mode, and a free-spooling mode. A wave washer urges the ratchet plug into one of the apertures once the ratchet mode is determined.
