Electric Single Drum Mooring Winch

All kinds of anchor winch are basically the same in function, including sprocket wheel, mooring drum, clutch and brake.These functional units are arranged on the same main shaft driven by power.

The warping drum (auxiliary drum) at the end of the main shaft usually rotates with the main shaft, and the sprocket is controlled by an independent clutch and brake.When the clutch is closed, the sprocket wheel and the main shaft bite together, which can be rotated together with the main shaft, thus the anchor chain can be twisted in or sent out.When the clutch is disengaged, the sprocket wheel does not rotate with the main shaft, which can be used for anchoring or mooring.The brake is used to stop the cable or control the speed of loosening.When the brake is tightened, the sprocket is secured to the body of the windlass and cannot rotate.Ships can be equipped with a double sprocket windlass.For large ships or ships with large bulbous nose head, two single-chain wheel windlass (or single-side windlass) separated from the right and left are usually set because of the large distance between the right and left anchor pipe.
