Steel wire rope sling is processed with steel wire rope as raw material, and the rope mainly used for hoisting, traction, tensioning and load-bearing is called steel sling. Wire rope sling has the characteristics of high strength, light weight, stable work, and not easy to break the whole rope suddenly. It is widely used in steel, chemical, transportation, port and other industries. The types of steel wire ropes used are phosphated steel wire rope, galvanized steel wire rope, stainless steel wire rope and smooth steel wire rope. Among them, the galvanized steel wire rope has corrosion resistance, and the phosphated steel wire rope has abrasion resistance and corrosion resistance.
Steel wire rope sling can use galvanized steel wire rope as raw material when it is used in wet or open-air environment to enhance the anti-rust performance.
In addition to the wear of the outer layer of the steel wire sling, the wire sling is mainly broken due to metal fatigue caused by repeated bending when bypassing the hook and the suspended object. Therefore, the ratio of the hook or the suspended object to the diameter of the wire rope determines the service life of the wire sling Key factor.
Steel wire rope slings shall be scrapped when the degree of wear and corrosion of the surface layer or the number of broken wires in each twisting distance exceeds the specified value.
Steel wire rope slings are mainly used in the transportation of high-strength ropes, such as lifting and pulling. It is strictly forbidden to stand under the suspended object or pass on the object during use.
