Capstan
A capstan is a vertical-axled rotating machine used on ships for winding ropes, cables, and hawsers. It consists of a drum, or barrel, turned by a crank, and a vertical spindle, which provides the axis of rotation. The capstan is used for various purposes on board a ship, such as weighing anchor, mooring, and hauling cargo. The capstan is usually powered by steam, electricity, or hydraulic power. The size and power of the capstan depend on the size of the ship and the weight of the loads it is required to handle.
