KOCKUMS HYDRAULIC BRAKE FOR WINDLASS TYPE ASW 401

Although there are other important factors, the main cause of losing anchors and chain cable during anchoring, particularly in large ships, is too high a cable speed. The article discusses the rapid decrease in the coefficient of friction between the braking surfaces of a windlass as the temperature of these surfaces rises, and recommends that cable speed should be kept constant at about 1 metre per second and should not, in any event, exceed 2 m/sec. Cable speed is more easily controlled with a hydraulically-operated brake than with the manually-operated type. The article includes numerical and other data to demonstrate the advantages of adequate control of cable speed, together with a description of a hydraulic automatic speed-control system.
