Capstan (tool)

A capstan is a cylindrical tool, often found on ships, used for applying rotational force. It helps in pulling heavy loads, such as ropes or cables, making tasks like anchoring or mooring vessels easier. Typically, a capstan consists of a vertical spindle that can be rotated by hand or powered by a motor. As the capstan turns, it winds the rope around itself, increasing the mechanical advantage, allowing a small force to lift or move much heavier weights. This tool is essential for maritime operations and in other industries where heavy lifting is required.
