Description

Technical Field

[0001] The utility model relates to the technical field of gangway ladder turning devices, in particular to a ship gangway ladder turning device. Background Art

[0002] The gangway is usually stored inside the ship's side and is released and arranged obliquely along the side of the ship when in use. It is a ladder for people to get on and off the ship. The gangway mainly consists of a gangway and a tower. The gangway is fixed on the tower. The ship is gradually brought close to the gangway so that people can reach the landing by climbing the gangway. When the ships are moored to each other, the berths and the ships are always changing. Generally, a fixed-length gangway is used, which requires several people to cooperate with each other to operate. Due to changes in the berthing position and berthing distance, it is impossible for people to always cooperate in the operation at the berthing point.

[0003] The existing ship gangway ladder flipping device is difficult to place for ship ladders that bear heavy loads or dock at a long distance. The large size of the gangway ladder makes it difficult to place the ship ladder. In addition, the gangway ladder is easily affected by factors such as sea breeze when it is raised and lowered, and it will shake when flipped, which will affect the problem of stable and safe erection.

[0004] Therefore, a marine gangway turning device is proposed. Utility Model Content
