Steel Wires are made of high quality carbon steel, which can be cold-drawn and heat-treated for many times to achieve high strength. Steel wire rope made of galvanized steel wire can be used in wet or open air environment to enhance rust resistance.
The diameter of Steel Wires, number of wires, number of wires per share, tensile strength and adequate safety factor can be selected for each purpose. The specifications of steel wires can be found in the relevant manual. Besides the wear of steel wire rope, the main reason is that metal fatigue is caused by repeated bending when bypassing pulley and drum. Therefore, the ratio of pulley or drum diameter to wire rope is an important factor that determines the life of wire rope. The ratio is large, the bending stress is small, the life is long, but the structure is huge. The appropriate ratio must be determined according to the situation of use. The wear and corrosion of the surface layer of the wire rope or the number of broken wires in each twist distance exceeds the specified value should be scrapped.
