For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0019] A special spreader for lifting a transport container includes a boom 1, a guide frame 2, a pneumatic system 3, a positioning plate 4, a support plate 5, and a connecting shaft 6. The boom 1 is suspended on both sides of the support plate 5 through bolts and connecting blocks, the guide frame 2 is connected to the support plate 5 through stud bolts, the pneumatic system 3 is fixed on the support plate 5 through a bracket and a valve, the positioning plate 4 is fixed in the middle of the support plate 5 through screws, and the connecting shaft 6 has a clearance fit with the through hole of the support plate 5, and its axial displacement is restricted by a stop block on the outside.

[0020] The described boom 1 can rotate locally around the installation groove on the support plate 5, and is designed with a special-shaped hole at the bottom for mating with the trunnion 7 of the transportation container. It is the main hoisting force-bearing component with a lifting load of 40t. The guide frame 2 is used for vertical positioning during underwater hoisting to ensure centering when the special-shaped hole of the boom is connected to the trunnion 7 of the transportation container.

[0021] The described pneumatic system 3 includes a bracket 8, a gas source pipe 9, a cylinder 10, and a valve 11, as shown in the appendix Figure 2 . The bracket 8 is used for installation and positioning. The gas source pipe 9 is connected to the gas source for input of compressed air. By changing the input and output directions of the gas source, it drives the cylinder 10 to expand and contract to realize the opening and closing of the two booms 1. The valve 11 is used for gas venting in case of cylinder failure.

[0022] The described positioning plate 4 and support plate 5 are mainly used for positioning, connection, and support of the boom 1 and the pneumatic system 3.

[0023] The described connecting shaft 6 is mainly used for connecting with the hook of the bridge crane through a spreader hook during hoisting to complete the hoisting operation.

[0024] During hoisting operations, connect the spreader connecting shaft 6 with the hook of the bridge crane through a spreader hook. Control the bridge crane to lower the spreader until the guide frame 2 contacts the trunnion 7 of the transportation container. After observing the centering of the trunnion 7 of the transportation container and the special-shaped hole of the boom 1 through an underwater camera, turn on the pneumatic system 3 to control the gas source, control the boom 1 to close, let the trunnion 7 of the transportation container pass through the special-shaped hole of the boom 1, control the bridge crane to slowly rise. After the trunnion 7 of the transportation container is locked with the special-shaped hole of the boom 1, start the flipping and hoisting operations.
