Technical Field

[0001] This utility model belongs to the field of marine engineering technology, and specifically relates to a hydraulic ship gangway. Background Technology

[0002] During ship berthing operations, gangways serve as a vital passage connecting the vessel to the dock, widely used in scenarios such as personnel embarking and disembarking and cargo transfer. However, traditional ship gangways are mostly fixed or simple mechanical structures, making adjustment difficult and operation inconvenient. They are ill-suited to adapting to the changing needs of different ship types, deck heights, and dock environments. Furthermore, existing gangways generally lack automated control functions, relying on manual operation, which is not only labor-intensive but also poses certain safety hazards in complex sea conditions.

[0003] In existing technologies, traditional ship gangways mostly adopt fixed or semi-automatic structures, which generally suffer from problems such as difficulty in adjustment, inconvenient installation, and low degree of automation. They are difficult to adapt to the diverse requirements of different ship types and dock environments for gangway height, angle, and length. In addition, gangways rely on manual operation, which is labor-intensive, not stable in operation, and poses certain safety hazards. Some gangways with hydraulic drive have complex structures, poor control precision, and do not have automatic extension and retraction functions, which affects their applicability and ease of use.
