The wire rope is a helical wire bundle made of steel wires with mechanical properties and geometric dimensions that meet the requirements. The wire rope is composed of steel wire, rope core and grease. A steel wire rope is a rope that is twisted into strands from multiple layers of steel wires, and then a certain number of strands are twisted into a spiral shape with the core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, not easy to break the whole rope suddenly, and reliable work. In 1834, European Olubert invented the world's first steel wire rope (smooth steel wire rope).
Wire ropes can be classified according to the material, surface condition, twisting method and purpose of the wire rope. Galvanized Wire Rope,Steel Wire Rope For Oil Field,Lifting Wire Rope,Traction Wire Rope Rugao Yaou Import & Export Trade Co., Ltd , https://www.ntyaous.com
