The degree of mechanization and automation in opening and closing hatch covers directly affects the labor intensity of personnel, as well as the loading and unloading production efficiency and berthing time of ships. The water tightness, strength, and reliability of the hatch cover are related to the quality of cargo transportation and the safety of the ship.
