Gantry cranes used to unload ships at the port shore require the gantry crane wire ropes to have good fatigue resistance. The longer the service life, the better. This can improve the production efficiency of loading and unloading containers and reduce the number of new rope replacements and gantry cranes. For downtime, manganese phosphate coated steel wire ropes should be preferred, which can meet the above requirements and have a service life that exceeds that of imported steel wire ropes.
Manganese-based phosphate-coated steel wire ropes are produced using China’s patented technology. The rope-making steel wires are treated with manganese-based phosphate coatings. The phosphate coating greatly improves the wear resistance and corrosion resistance of the steel wire surface. , the fatigue life is 3-4 times that of smooth steel wire ropes with the same structure, and the quality stability and reliability are higher. The price of purchasing manganese phosphating coated steel wire ropes is only one-third of the steel wire ropes imported from Europe, and the service life is But it far surpasses imported steel wire ropes, so it is very cost-effective.
Manganese-based phosphating coating. The surface of steel gears in automobile transmissions is treated with manganese-based phosphating. It can ensure that the gears will not be worn and damaged for more than ten years. In addition to improving wear resistance, it can also improve corrosion resistance. Nature, the air in ports near the sea or river is very humid, and smooth steel wire ropes are very easy to rust. Manganese phosphate-coated steel wire ropes are not only wear-resistant but also corrosion-resistant, which is the reason for their extremely long service life. For reference only
