[0002] A lifting lug is a stress-bearing component installed on equipment for lifting. It is an important connecting component in equipment hoisting, directly related to the hoisting safety of large equipment. The lifting lug and the steel wire rope are usually fixed by wedge block self-locking. The fitting degree between the wedge block and the steel wire rope and the tightening degree of the steel wire rope clamp have important influences on the reliability of the lifting lug installation.
[0003] For example, the Chinese patent document with the authorization announcement number CN216940493U discloses a safety and rapid installation device for a steel wire rope wedge joint of a large-tonnage crane. The device includes a workbench. One side of the top of the workbench is fixed with a retaining seat. The other side of the top of the workbench is provided with a slideway. A slider is arranged inside the slideway. A traction mechanism is arranged on the top of the slider. The traction mechanism includes a mounting plate, a fixing frame, an electric hoist and a traction rope. A fixing frame is arranged on the top of the mounting plate. An electric hoist is arranged on the top of the fixing frame. A traction rope is wound and connected in the middle of the electric hoist.
