Product Descriptions
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 capstan, anchor capstan, electric capstan, hydraulic capstan, vertical capstan, horizontal capstan 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.

Design Structure of Capstan
- These capstans have good lubrication system, the oiling points are obvious and easy to see, or they have marks if they are not easy to see
- They are equipped with automatic control brake device, and they are able to bear 1.5 times of mooring load
- The capstans can reverse and the mooring speed can be regulated according to needs
- The appearance of the drum and the diameter of it comply with the relevant standards, like the rules of GB 7390
- Protection device will be set if some mechanical parts of the capstans cannot bear the locked rotor load (or the maximum load) of the prime mover
- Mechanism used for preventing the drum reversal will be set for the capstans with manpower driving mechanism
