BÀI 28 – (Passage 28)

Đọc hiểu

The windlass is the usual anchor-handling device where one machine may be used to handle both anchors . A more recent development, particular on larger vessels, is the split windlass where one machine is used for each anchor.

The rotating units of a split windlass consist of a cable lifter with shaped snug to grip the anchor cable , a mooring drum for paying out or letting go of mooring wires and a warp end for warping duties. Each of these units may be separately engaged or disengaged by means of a dog clutch, although the warp end is often driven in association with mooring drum. A spur gear assembly transmits the motor drive to the shaft where the various dog clutches enable the power take-off. Separate band brakes are fitted to hold the cable lifter and the mooring drum when the power is switched off.

The cable lifter unit is mounted so as to raise and lower the cable from the spurling pipe, which is at the top and the chain or cable locker.

Anchor capstans are used in some installations where the cable lifter rotates about a vertical axis. Only the cable lifter unit is located on deck, the driving machinery being on the deck below.
