The steel wire is made of high-quality carbon steel and can reach high strength after many cold drawing and heat treatment.Work places such as wet or open environment can use galvanized steel wire twisted into wire rope to enhance rust prevention performance.Steel wire rope in various industrial countries are standard products,according to the use needs to choose its diameter,rope strands,wire per share,tensile strength and sufficient safety factor,its specifications can be found in the relevant manual.In addition to the wear of the steel wire of the outer layer of the wire rope,it is mainly due to the fatigue of the crane accessories caused by repeated bending around the pulley and the drum,so the ratio of the pulley or drum to the diameter of the wire rope is an important factor in determining the life of the wire rope.The ratio is large,the bending stress of the steel wire is small,the life is long,but the mechanism is huge.The appropriate ratio must be determined according to the occasion of use.The wear and corrosion degree of the surface layer of the wire rope or the number of broken wires per screw spacing exceeds the specified value should be scrapped.Wire rope is mainly used in the transportation of high-strength wire ropes such as lifting and pulling.
