capstan is a type of device commonly used on ship deck or on the shore to tighten or loosen ropes or cables during anchoring and mooring a ship. There are generally mooring capstans, anchor capstans, electric capstans, hydraulic capstans, vertical capstans, horizontal capstans etc. Unlike modern winches, which have cable or rope mounted on a drum, the capstan winch does not hold the entire length of rope or cable but instead acts as an intermediary between one end of the rope or cable and the other, the drum just winds the rope or cable but not store it. Its pull and load are generally in the range of 0.5t – 25T.

The main parts of capstans include clutch control knob, drum cover, drum, brake band, windlass brake handle, wildcat, drum controller handle, electric motor, reducer, etc.
