An anchor windlass is a machine that restrains and manipulates the anchor chain on a boat, allowing the anchor to be raised and lowered by means of chain cable. A notched wheel engages the links of the chain or the rope. Working Principle: The power unit drives the transmission device, causing the sprocket to rotate. When dropping the anchor, the brake is released through the control device. The sprocket rotates in the opposite direction due to the weight of the anchor chain, gradually releasing the anchor chain. When weighing the anchor, the motor drives the sprocket to rotate forward, winding the anchor chain on the sprocket and pulling the anchor from the seabed.

Main Structure

Power Unit

Electric Type: Motors, including DC and AC motors, are used. DC motors have good speed regulation and high starting torque. AC motors are simple, reliable, and easy to maintain.

Hydraulic Type: Driven by a hydraulic pump station, it offers high power output and smooth operation, being suitable for large ships.

Transmission Device

Reducer: It reduces the rotational speed of the motor and increases the output torque to enable the windlass to raise and lower the anchor chain at an appropriate speed and force.

Sprocket: It meshes with the anchor chain to wind and unwind it.

Control Part

Electric Control Box: It controls the start, stop, forward and reverse rotation, and speed regulation of the motor.

Control Handle: It can be used for local or remote control on the bridge or beside the windlass.

Brake Part

Brake Device: It can quickly brake the anchor chain to prevent it from sliding freely.

Clutch: It connects or disconnects the sprocket and the transmission shaft for maintenance and special operations.

Features

Gypsy: single, double or other

Warping head: none, one or two

Brake and clutch: manual or hydraulic operated
