[0002] A ship is a means of transport that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. Like other means of transport, ships need to be inspected and maintained from time to time to ensure that they can be used normally.

[0003] During the ship maintenance process, the ship needs to be lifted up for comprehensive maintenance to prevent it from being partially sunk below the water surface and difficult to repair. However, the existing ship lifting devices generally use ropes for lifting, which have strict requirements on the lifting position and are prone to tilting when lifting the ship, resulting in instability of the lifted ship, which may cause the ship to slip and cause damage to the ship.

[0004] To this end, we provide a ship maintenance lifting device to solve the above problems. Utility Model Content
