A system for automatically switching between a high speed and a low speed state for rotating the drive shaft of a manual hoist.

A system for automatically switching between a high speed and a low speed state for rotating the drive shaft of a manual hoist.

A winch assembly includes a base having first and second sides, a first shaft supported by the base and supporting a gear and a reel, and a second shaft supported by the base and supporting a ratchet gear. The ratchet gear meshes with the gear and a pawl, and a handle is attached to the second shaft for rotation thereof. The winch includes a cover having a top movable between first and second positions and first and second sides rotatably supporting the top. The first side may include a first arm extending toward and engaging a second arm extending from the second side. The top may include hooks for engaging a shaft extending between the sides of the cover. The sides of the cover may each include at least one retainer clip and the top includes corresponding lugs for engaging the at least one retainer clips.
