Capstan

A capstan is a robust device used on ships and in various industries to move heavy loads. It consists of a rotating drum around which a rope or cable is wound. When the drum turns, it pulls the attached line, enabling the movement or lifting of heavy objects. Capstans are often used for tasks like hoisting sails on boats or securing vessels to docks. By using leverage and mechanical advantage, capstans make it easier to handle heavy weights, enhancing efficiency in manual tasks.
