Gangway winch usually consists of motor, reducer, reel, brake, control system and other parts. Its core function is to drive the reel through the motor, so that the wire rope or chain is wound or released on the reel, so as to realize the lifting and retracting of the gangway.

Motor: As the power source of the gangway winch, the motor usually adopts AC or DC motor, which has high torque and stable speed to meet the demand under different working conditions.

Reduction device: The reduction device is used to reduce the speed of the motor and increase the torque to ensure that the gangway has sufficient power and stability during the lifting and lowering process.

Reel: The reel is one of the core components of the gangway winch and is used to wrap the wire rope or chain. The design of the reel usually takes into account the arrangement and force distribution of the wire rope to avoid crossing or wear of the wire rope during the winding process.

Brake: The brake is used to maintain a stable position during the gangway rise and fall, preventing the gangway from sliding down due to gravity when it stops. The reliability of the brake is directly related to the safety of the gangway operation.

Control system: The control system usually includes the operation panel, limit switch, emergency stop button, etc., which is used to realize the remote control and monitoring of the ramp winch. Modern gangway winches are usually equipped with intelligent control systems capable of automated operation and fault diagnosis.
