Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure production, and in particular relates to a hoisting clamp for steel structure production. Background Art

[0002] Steel structures refer to a combination of multiple parts connected together by welding, riveting or threaded connections. These parts are interconnected and constrained to form an organic whole. During the production of steel structures, multiple parts need to be assembled together. During the assembly process, lifting fixtures are used to lift the steel structures. Some of the existing lifting fixtures are special fixtures that are only suitable for the same type of steel structures. This type of fixture is customized according to the shape of the steel structure, with good clamping effect, but poor versatility. It needs to be replaced when clamping different steel structures. Another type of lifting fixture with strong versatility is usually a structure such as a lifting ring or a lifting rope. This type of structure has insufficient clamping effect on the steel structure and is less safe than a special fixture. Utility Model Content
