Hoisting accessories in one of the important is the wire rope, it determines the safety of the crane hoisting goods, good wire rope safety degree is high, on the contrary, the safety degree is low, below we explain the wire rope:

Steel wire made of high quality carbon steel, after many cold drawing and heat treatment can reach very high strength. Wet or open environment, such as the workplace can be used galvanized steel wire rope wrung, to enhance anti-rust performance. Wire rope in each industrial country is a standard product, according to the use of the need to choose its diameter, the number of rope, steel wire per share, tensile strength and sufficient safety factor, its specifications and models can be found in the relevant manual. Apart from the wear of steel wire rope layer, mainly due to the fatigue of crane accessories caused by repeated bending around the pulley and the reel, the ratio of pulley or reel to the diameter of steel wire rope is an important factor to determine the life of steel wire rope. The ratio is large, the bending stress is small, the life is long, but the mechanism is huge. The appropriate ratio must be determined according to the occasion of use. When the degree of wear and corrosion of the surface layer of steel wire rope or the number of broken wires in each screw distance exceeds the specified value, it shall be scrapped. Steel wire rope is mainly used in hoisting, hauling and other transportation requiring high strength wire rope.
