Steel structure has gradually become the mainstream structural form, and the requirements for its display effect have been continuously improved. At the same time, the public has become more and more recognized of the structural form of steel structure. In the process of hoisting and construction of steel structure components, automobile cranes or tower cranes are usually used for hoisting construction. When automobile cranes or tower cranes are used for steel structure hoisting construction, the lifting points of steel structure components are set at the pre-welded lifting ear connectors. When lifting steel structure components, they must be more than two meters above the ground before they can be rotated. When the steel structure components are 200mm above the position, they are aligned with the bolt holes and cross lines and slowly fall down. This process requires sufficient space to complete the hoisting operation. The above-mentioned steel structure component hoisting method is not applicable to working conditions where there is insufficient space indoors and the ground bearing capacity is insufficient.
