The manual QRH is mainly composed of the winch, locking mechanism, releasing mechanism, cable hook, hook housing, control box, footswitch, and chassis. A thin cable guiding rope is used to tow the mooring rope to the vicinity of the cable hook and the mooring rope is then hung to the cable hook. This completes the cable fastening operation of one cable. When needing release, the operator only need to pull the release lever, then the locking mechanism will open. The hook flips under the pulling of the cable, then the cable releases from the hook. This is fast and convenient.
