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.
