Description

Technical Field

[0001] The utility model relates to the field of steel frame hoisting, in particular to a quick anti-sway device for hoisting steel frames. Background Art

[0002] Currently, hoisting operations for steel frames, especially steel roof structures, often involve hooking the steel frame's two attachment points with a crane's two hooks. The steel frame is then lifted and transported to the desired installation location for subsequent installation. This process presents a problem: Because the hooks are connected to the lifting end of the crane via wire rope, the steel frame inevitably wobbles during the hoisting process. Once it reaches its intended installation location, the wobbling takes a long time to settle, impacting the efficiency of subsequent installation operations. Utility Model Content
