Description

Technical Field

[0001] The utility model relates to the technical field of lifting components, in particular to a special lifting device for ship clearance. Background Art

[0002] Ship engines, components, and non-standard cargo are difficult to transport within a ship and require ship lifting equipment. Cranes are commonly used within ship cabins, and cranes typically use slings to lift heavy objects.

[0003] In the prior art, for example, a sling and a lifting assembly proposed in announcement number CN214359763U inserts a lifting slot into a hole in an upper plate to connect the sling to the ship structure, then installs shackles and wire ropes in the lifting holes on both sides of the lifting slot, and then lifts the ship structure. Since the width of the lifting slot in the above-mentioned sling cannot be changed, when the thickness of the upper plate is thick, the lifting slot is difficult to insert into the hole of the upper plate. When the thickness of the upper plate is thin, although the lifting slot can be inserted into the hole of the upper plate, a large gap will be formed between the two side walls of the lifting slot and the two side surfaces of the hole of the upper plate, so that the two side walls of the lifting slot cannot fit with the two side surfaces of the upper plate. During the lifting process, the ship structure will shake significantly. Therefore, the applicability of the above-mentioned sling is poor. Utility Model Content
