(1) Drum (with rope grooves): Wraps anchor chains/cables to ensure orderly winding and unwinding.
(2) Power device (hydraulic motor/motor): Provides driving force and adjusts the winding/unwinding speed.
(3) Braking system (working + emergency brakes): Controls start and stop; locks the drum in case of failure to prevent cable slipping.
(4) Reduction mechanism (gearbox): Reduces speed and increases torque to meet the traction requirements of operations.
(5) Control system (operation console, tension controller): Adjusts the operating status and monitors tension to prevent breakage.
(6) Base: Fixed on the deck to bear loads and prevent displacement.
