1.1 Capstans and winches
A capstan is a vertical rotating spindle used on yachts and boats to wind or unwind ropes or chains. It is commonly used when mooring and anchoring and allows the crew to handle heavy loads with ease. Turning the capstan retracts or releases the rope or chain, pulling the vessel closer to or away from the quay. Capstans can be manually or electrically operated, the latter being increasingly common on modern ships.The speed of the capstan can be single speed, double speed and three speed depending on your requirements. There are different types of marine capstan:
According to the power source, it can be divided into electric capstan and hydraulic capstan
According to the structure, it can be classified intovertical capstan and horizontal capstan
According to the uses, there are anchor capstan and mooring capstan to choose from:
The features of marine capstan are briefed below:
- Electric or hydraulic power
- Anchor chain wheel for independent anchoring operation
- Multiple control options
- Fail-safe braking system
- Emergency stop device
- Marine coating system
- Variable speed is optional to meet different working requirements
- Factory assembly and testing
A winch is a mechanical device used on boats and yachts to lift, lower or pull loads. Unlike the capstan, which is vertical, a winch has a horizontal drum around which the rope or chain is wrapped. Winches are commonly used when setting sail, raising flags, lowering lifeboats, or pulling anchors. They can be manually, electrically or hydraulically operated, depending on the size of the vessel and the load to be handled.
In summary, bollards, capstans and winches are important components of the equipment of ships and yachts, each fulfilling different functions and used in different manoeuvres. Bollards serve as attachment points for ropes and lines, capstans allow easy winding and unwinding of ropes or chains, and winches are used for lifting, lowering or pulling loads.
