Capstan (mechanical device)

A capstan is a type of mechanical device used primarily for winding or hauling heavy ropes, cables, or chains. It typically consists of a vertical rotating drum with a handle or motor to provide force. When the rope is wrapped around the drum and turned, the capstan generates a powerful pulling force, making it easier to lift or move heavy objects, such as boats or large equipment. Capstans are commonly found on ships, construction sites, and in various industrial applications, where they enhance efficiency and safety in handling heavy loads.
