Abstract
A manual winch includes a housing supporting a rotatable reel, a ratchet assembly coupled to the reel movable between an engaged and disengaged position, and a load releasing system for moving the ratchet assembly system to a disengaged position. The ratchet assembly includes a rotatable ratchet gear which is adapted to be engaged by a pivotable locking pawl. The locking pawl is pivotable into and out of engagement with the ratchet gear for moving the ratchet assembly between the engaged and disengaged position. The locking pawl is mounted on a movable base which secures the locking pawl to the housing. The load releasing system includes a linear actuator for moving the relative position of the base relative to the ratchet gear and the housing, and a separate brake for holding the reel and ratchet gear in position under a load.
