Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a heavy-duty structural part lifting device. Background Art

[0002] Heavy structural parts are various components that can constitute the entity of large mechanical equipment after hoisting, assembly and installation during the manufacturing process of large mechanical equipment. These structural parts often have large size and weight, so heavy structural parts need to be hoisted, and for this reason a hoisting device is needed.

[0003] At present, there are still some shortcomings in the traditional lifting device. After the hook is connected and fixed to the structural part, the hook will drive the structural part to rise, and then the structural part will be lifted by the cable. Since the rope will shake during the rising process, the structural part will also cause the steel beam to shake, which affects the stability of the lifting work, reduces the safety of the lifting operation, and is not conducive to the precise docking between mechanical structures. For this reason, we propose a heavy-duty structural part lifting device. Utility Model Content
