Description

Technical Field

[0001] This utility model relates to the technical field of ship lifting devices, specifically a ship lifting device. Background Technology

[0002] Marine lifting systems are essential mechanical devices specifically designed for vessels in both maritime and inland waterways. They facilitate the safe transfer of cargo, personnel, or equipment between the vessel and docks, other ships, or underwater facilities. These systems include, but are not limited to, cranes, elevators, lifting platforms, and gangplanks. They significantly improve loading and unloading efficiency and ensure the safety and stability of operations. Depending on the specific application and requirements, these lifting systems can possess varying load capacities, operating ranges, and adaptability to different weather conditions. With technological advancements, modern marine lifting systems are increasingly becoming automated and intelligent, not only improving work efficiency but also enhancing navigational safety.

[0003] In existing technologies, the loading and unloading of cargo on ships, especially for palletized cargo, often requires a significant amount of time to secure and untie the pallets. This manual securing method is not only inefficient but also prone to human error, leading to cargo damage or safety accidents. Furthermore, operations in adverse weather conditions further increase the difficulty of the process, posing a threat to the safety of personnel and cargo. Utility Model Content
