Capstan (device)

A capstan is a mechanical device used to control or move heavy loads, commonly in maritime, industrial, and theatrical settings. It consists of a vertical or horizontal rotating drum around which ropes, cables, or lines are wound. By turning the drum, it provides a mechanical advantage, making it easier to raise, lower, or hold large objects or loads with less effort. Essentially, a capstan functions like a large, powerful winch that uses friction and leverage to help manage heavy or awkward loads efficiently and safely.
