What Is A Windlass?

A windlass is a device used to draw and release anchors and chains. The windlass is usually installed on the main deck of the ship's bow and stern for the ship to weigh anchor and anchor the cable.

The windlass is mainly composed of base, support, anchor wheel, brake, sprocket, gearbox, electric control system (except manual windlass).

According to the different power, windlass can be divided into manual windlass, electric windlass, electric hydraulic windlass and steam windlass.

The sea ship anchor machine is mainly electric hydraulic anchor machine and electric anchor machine. In order to control the operation of the windlass, the power windlass is equipped with a master controller, which can carry out reversing operation and multistage variable speed control.

The installation of the windlass on the ship should ensure that the package Angle between the anchor chain and the sprocket is 117 ~ 120 degrees. In addition, according to the anchor chain diameter can be divided into φ12 ~ φ120mm and other specifications, according to the drum distribution can be divided into one side and two sides. The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, the variable speed of several stages, and the electrical system.

As one of the ship's "four engines" (main engine, auxiliary engine, steering engine, Windlass), the anchor machine plays a huge role in fixing the ship's position, assisting turn-around, leaning away from the dock, slowing down the ship's speed, and emergency avoidance.
