How much is the elevator wire rope with a diameter of 10 mm per meter? The main specifications of elevator wire rope are 8 × 19S+NF and 8 × 19Sigi WR, with diameters of 8, 10, 12 and 13 mm. Shuanggang double strength, 45 steel, 65 steel, 1370N Universe mm2Magne1770MPA, single steel, single strength, 65 steel, 1770N/mm2. According to the national standard, the elevator rope core is sisal and PPC synthetic fiber. The specification and model of the high-speed elevator wire rope is 819Syst7ppweight, high strength, light weight, good flexibility, impact resistance, safety and reliability. The wire rope used under normal circumstances will not break suddenly, but it may be damaged because the load exceeds its ultimate breaking force. The damage of the wire rope is a precursor, always starting from the broken wire, the sudden fracture of the whole rope rarely occurs, and the wire rope is widely used in cranes. The damage of wire rope will lead to serious consequences, so wire rope is not only one of the important parts of lifting appliances, but also the key link to ensure the safety of lifting operation data expansion: the main varieties of wire rope are phosphating coated wire rope, galvanized wire rope and stainless steel wire rope. The failure of steel wire rope is caused by fretting fatigue, manganese phosphating and zinc-manganese phosphating belong to wear-resistant phosphating, which can improve the wear resistance and corrosion resistance of steel wire surface, and its fatigue life is three times longer than that of smooth wire rope. the highest test has reached four times. The damage of the wire rope is a precursor, always starting from the broken wire, the sudden fracture of the whole rope rarely occurs, and the wire rope is widely used in cranes. The damage of wire rope will lead to serious consequences, so wire rope is not only one of the important parts of lifting appliances, but also the key link to ensure the safety of lifting operation.
