steel wire

Steel wire rope in the industrial countries are standard products, according to use need to select its diameter, numbers of strands, each strand of wire number, tensile strength and adequate safety factor and its specifications can be in the manual check. Steel wire rope in outer wire wear, mainly due to round the pulley and the drum repeated bending caused by metal fatigue and gradually broken, so sheave or drum and wire rope diameter ratio is an important factor to determine the service life of the rope. Ratio is large, the steel wire bending stress is small, long life, but the body is huge. Appropriate ratio must be determined in accordance with the use of the occasion. The wear and corrosion degree of the surface layer of the steel wire rope or the number of broken wires in each screw must be discarded when the specified value is exceeded.
The wire rope is mainly used in hoisting, transportation and transportation in need of high strength rope.
