Description

Technical Field

[0001] The utility model relates to the technical field of wire rope hangers, in particular to a wire rope hanger capable of reducing wire rope loss. Background Art

[0002] Wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. Wire rope slings are processed with wire rope as raw material. They are mainly used for lifting, traction, tensioning and load-bearing ropes. Wire rope slings have high strength, light weight, stable operation, and are not easy to break suddenly. They are a tool that acts as a flexible connection between lifting and hoisting tools and the hoisted goods. In actual applications, wire rope slings are widely used in lifting operations in ports, sea and land transportation, mining, metallurgy, forestry, petrochemical, ships, railway bridges, power construction, aerospace and other industries.

[0003] However, it still has some disadvantages. For example, when the wire rope is connected to the lifting ring, the two ends of the wire rope need to be bent and connected to the lifting ring, and then the wire rope is fixed by an aluminum sleeve to form a fixed space with the lifting ring. At this time, the two ends of the wire rope are in an exposed state, and the staff can be easily scratched, which poses a certain safety hazard. In addition, the wire rope has no buffering ability, which reduces the service life of the wire rope.

[0004] In order to solve the above problems, the present application proposes a wire rope hanger capable of reducing wire rope loss. Utility Model Content
