With high-quality carbon steel wire, cold drawing and heat treatment after repeated high strength can be achieved. Wet or outdoor environment in the workplace can be twisted galvanized steel wire rope, in order to enhance rust resistance. Rope in all industrial countries are standard products, which can use to choose its diameter, number of strands, number of wires per strand, tensile strength and sufficient safety factor, and its specifications are available in the relevant manual Richard. Except the wire rope wear layer, the main deflection pulleys due to repeated bending and roll, and gradually cause metal fatigue fracture, so the rope pulley or reel diameter ratio is an important factor in the decision life rope. The ratio of large, wire bending stress, long life, but a large organization. You must use the occasion to determine the appropriate ratio. Surface layer of wire rope wear, corrosion or broken wires within each twist at the number exceeds the specified value should be scrapped. Wire rope is mainly used in lifting, transportation and other high strength pull cord of transportation.
