Marine capstan is an important deck machinery useon boats and ships to help control and manipulate ropes and cables.It has the same function as a mooring winch. It consists of a vertical or horizontal drum that rotates and winds up the ropes or cables as they are pulled. The capstan is powered by a motor or manually by a team of sailors turning a crank handle. The main purpose of a marine capstan is to provide a mechanical advantage, making it easier to control heavy loads and perform tasks such as raising and lowering sails, dropping and retrieving anchors, and docking the vessel.
The electric capstan can also be delivered wit single, double or three speed motor.
Capstan is a a vertical axis rotating machine used on boats to increase the seafarer’s pulling force when towing ropes and cables. The principle is similar to that of a windlass, which has a horizontal axis.
Capstan winch is commonly found in marine, forestry, mining, construction and industrial industry, for use when moving heavy objects to increase the pulling force.
Windlass is a sort of winch in which rope is wound around a drum. It is used to lift heavy objects.
Capstan is a vertical cleated drum, which rotates on a vertical spindle. It is widely used, especially on ships, to move or raise heavy weights or exert great power by rope traction.
