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.

1. A winch mechanism for engagement with a pinion gear, the pinion gear being rotatable in a forward direction and a reverse direction, the winch mechanism comprising:a frame having a pair of sidewalls including at least one aperture disposed in one sidewall, the at least one aperture being proximate to an axle opening in one of the sidewalls; a ratchet including a ratchet arm and a ratchet plug, the ratchet arm enables repositioning of a pawl, the ratchet plug enables engagement of the ratchet with the frame; and the pawl having at least two teeth, the first tooth being in detente engagement with the pinion gear enabling a forward rotation of the pinion gear while blocking reverse rotation of the pinion gear, the second tooth being in detente engagement with the pinion gear enabling a reverse rotation of the pinion gear while blocking forward rotation of the pinion gear, each position of the ratchet and pawl position relative to the pinion gear being secured by detente engagement between the ratchet plug and one aperture of the at least one aperture.
