DEVICE FOR CONTROLLING THE BRAKING OF A WINDLASS

摘要

1313369 Automatic speed control BERGENS MEKANISKE VERKSTEDER A S 3 Aug 1970 [20 Dec 1969] 37419/70 Heading G3R A brake for a windlass which operates a ship's anchor has a drum carrying a number of magnets associated with a speed-detector which transmits pulses to a frequency-responsive relay. A hydraulic motor for operating the brake is controlled by an electro-magnetic valve which responds to the relay so that the speed of a released anchor is stabilized by applying or releasing the brake. An accumulator stores energy for operating the brake motor on failure of the normal supply. The pulses from the speed-detector are also transmitted to a unit for indicating the outboard length of the anchor-chain. The frequencyresponsive relay controls a further relay adapted to energize an alarm. The brake motor may be remotely controlled from the bridge.
