How to get off the Zhonglian 95-ton crane?

Truck crane is a kind of special equipment, which needs to be certified. On the basis of receiving crane operation training, operate in strict accordance with the operating instructions of Zhonglian crane. Crane users need high-quality steel wire rope, which should have long service life, high stability and reliability. Fretting fatigue is the main reason for the failure of steel wire ropes used in atmospheric environment. At present, the first preventive measure against fretting fatigue in the field of steel wire rope in the world is phosphating coated steel wire rope produced by patented technology. After manganese phosphating or zinc-manganese treatment, the surface wear resistance and corrosion resistance of wire rope are improved in an all-round way, and the fatigue life of wire rope is greatly improved. The fatigue life of smooth steel wire rope with the same structure is three times (under comparable conditions in laboratory), which can be verified by fatigue test. If you have a fatigue testing machine, you can do a comparative test yourself. This test result is the most credible, and the service life of wire rope is directly proportional to the fatigue life. If the fatigue life is long, the service life will be extended in proportion. According to the approximate price of steel wire rope market at present, the price of manganese phosphating coated steel wire rope is about 1.4- 1.6 times that of smooth steel wire rope, and the extension of service life is much higher than the price increase. Therefore, the daily average use cost of phosphating coated steel wire rope is only 40-55% of that of smooth steel wire rope, which is lower in use cost and higher in cost performance. .
