A hand winch or manual winch is a pulling or lifting device with a rope, strap, cable, or chain wound around a rotating drum that is operated by a hand crank. Manual winches typically have bolt holes at the bottom or side of the housing for mounting. Manual winches are usually made of steel and may be coated for protection against rust and corrosion. Many hand winches have a brake or self-locking mechanism for safety or holding a load in position. Manual cable winches have varying load capacities.
