capstan

This term is highly specialized nautical terminology, primarily used in maritime contexts. It describes a specific mechanical device designed to provide mechanical advantage through rotation, distinguishing it from a windlass, which typically has a horizontal axle.

In modern usage, the word is rarely encountered outside of sailing, naval history, or heavy industrial rigging. It carries a connotation of manual labor and collective effort, as traditional capstans often required multiple crew members to push bars around the drum to hoist heavy loads.
