The material of the 80 -level lifting chain is made of 20MN2 alloy steel, with high strength and good processing performance and welding performance. Generally, we talk about its weight. How much will someone say? How much will people say that they weigh them? The greater the load of the chain, the heavier it is relatively automatic. Because the diameter of the chain becomes larger. Take a 6mm chain, for example, 0.8 kg of weight per meter, and the standard load is 1 ton. The 8mm chain is 1.4 kg per meter, and the standard load is 2 tons. The larger the same load, the greater the self -weight.
