    How to confirm your anchor windlass line pull?

    If you want to save time and get a quick quotation with a drawing and specification, you had better get the right parameters. I think you get that as follow:

    1. According to your ship outfitting number and confirming of your anchor windlasses parameters

    Ship outfitting number formula is

    EN = △2/3+ 2hB+0.1A

    Molded displacement
    
    a Freeboard
    
    B Breadth
    
    d Draft
    
    h=a+∑hn
    
    

    Base on ship outfitting number and social classification, check the Equipment for Self-propelled Ocean-going Vessels.

    Confirm the chain size.

    Then use the below formula and calculate the line pull: 0.0475d2

    Principle of the electric anchor windlass

    principle electric anchor windlasses

    When the clutch is disengaged, the axle and drum rotate while the cable lifter does not rotate, used for anchoring or mooring; when the clutch is closed, the drum and anchor windlass gypsies rotate at the same time, used for anchoring or sending anchor when anchoring in deep water. The manual band brake is used for braking the wildcat to control the release speed of the chain.

    Hydraulic anchor windlass

    Comparing with electric power, hydraulics anchor windlass’s best advantage is supply bigger pull than electric anchor windlass.

    In this part, I am goting to take you through the constitute and principle of hydraulic anchor windlass.

    Composition of the hydraulic anchor windlass

    hydraulic anchor windlass mainly parts are hyd-motor, wildcat, foundation, warping head, wall support, Hydraulic operation valve,

    Principle of the hydraulic anchor windlass

    The motor drives the main oil pump to produce high-pressure oil, which is delivered to the oil motor through the high-pressure oil pipe and each functional control valve and drives it to rotate, and at the same time drives the load shaft connected with it to rotate synchronously, when the clutch is disengaged, the anchor windlass gypsies does not move, at this time the anchor machine can be used for cable winching or anchoring. When the clutch is closed, the anchor windlass gypsies pull and pay out the chain simultaneously, which can be used for anchor winching or anchor feeding in deep water anchoring.

    Vertical windlass winch and horizontal windlass

    This part let me explain to you difference between vertical windlass winch and horizontal windlass

    38mm vertical windlass capstan

    Honrizontal double gypsies hydraulics windlass refers to the anchor machine whose cable lifter shaft is horizontally arranged. Most of the anchor windlass equipment on board is horizontal.

    Vertical windlass capstan refers to the anchor equipment with the vertical arrangement of the gypsies shaft. It can reduce the deck area occupied by the anchor equipment and is mostly used in warships.

    One stopper of the anchor windlass system

    Generally speaking, the anchor system consists of an anchor, anchor chain, anchor chain barrel, chain maker, anchoring machinery, and auxiliary equipment.

    Anchor

    Anchor generates gripping force.

    Chain stoppers

    bow chain stopper

    Chain stoppers: Set between anchor machine and anchor chain cylinder.

    The function of the chain stopper is to bear the load of the anchor and anchor chain and protect the anchor machine. The chain makers for inland waterway vessels are as follows.

    (1) Spiral chain maker: used for large and medium-sized ships, safe and reliable in operation.

    2)Gates type chain maker: can be used for medium and small-sized ships.

    3)Short chain maker: only for small ships.

    Functions.

    ① fixing the anchor chain to prevent the anchor chain from slipping out.

    ② Transferring the grip force generated by the anchor and anchor chain directly to the hull to reduce the load of the anchor engine and protect the anchor engine.

    ③To bear the gravity and inertia force of the anchor when navigation.

    Anchor chain

    • connect anchor and boat;
    • transfer anchor-generated grip force;
    • lie down chain generates grip force due to friction.

    Chain gear

    The chain gear device is also called a chain release device. When the anchor hooks to the obstacle at the bottom of the river when anchoring; or when the anchor chain keeps slipping out due to the rapid current and the anchor machine cannot brake, the root end of the anchor chain should be

    The anchor chain should be disconnected quickly, and the chain should be abandoned. There are several kinds of chain abandonment devices for ships as follows.

    (1)Off-hook chain abandonment device: connect the off-hook with the eye plate of the anchor chain compartment.

    2)Short chain release device: The release hook is attached to a short section of the anchor chain and can release the anchor chain outside the anchor chain compartment.

    (3) Deck chain gear: The lever is connected to the snap ring of the release hook, and the handwheel can be operated on the deck to release the anchor chain.

    Terminology of the anchor windlass

    Chain pull capacity The working load is measured at the anchor and is derived from the anchor chain diameter and chain grade, etc.

    Line Lifting speed The average speed of anchor chain lifting should be not less than 9m/min when starting a long rainbow anchor and anchor chain.

    Overload pull Short-time overload capability necessary

    Holding load The maximum static load on the anchor chain that the anchor sprocket brake can withstand.

    Nominal Speed of windlass The average speed of collecting two anchor chains when there are three anchor chains submerged in the water and free hanging

    Marine-grade motor

    Anchor windlasses controlled by relay contactors generally use variable-pole speed regulation, so the motor generally requires two windings (or three sets of windings).

    The domestically produced AC electric anchor machine (fixed type product) is: dragged by a 16/8/4 three-speed squirrel cage asynchronous motor. There are two sets of independent windings, high-speed 4 poles, a separate set of windings, medium-speed 8 levels (YY), low-speed 16 poles (Δ), medium and low speed combined with a set of windings.

    YY-Δ variable-pole speed regulation is a constant power speed regulation, which can ensure a large torque at low speed (i.e., to meet the rated torque of 2 times the starting). The medium speed 8 stage (YY) is the rated stage.
