A manually operated winch system secures cargo to a transport vehicle. The winch system has a shaft rotationally mounted relative a frame. A ratchet drive mechanism controls rotation of the shaft. A handle received in the drive mechanism can be used both to control rotation of the shaft and to control operation of a pawl. The drive mechanism is configured such that tilting the handle moves a member axially. Sufficient axial movement of the member causes the pawl to disengage mating ratchet teeth and thereby allows the shaft to rotate freely. In some embodiments, an adjustment mechanism limits the extent to which the member can move axially.
