The lifting chain is an essential and important lifting device of the crane. The length of the chain can be adjusted according to the lifting height of the crane. It plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane. The allowable wear value of the lifting chain shall not exceed 10% of the bar diameter of the ring chain or the thickness of the auxiliary tools. From the plane where the main ring is not bent, the main ring shall be scrapped if it is twisted more than 10 degrees. It is forbidden to use the lifting chain if cracks, bending or twisting occur at any part of the lifting chain and there are stuck or stiff resistance between the ring hinges, which cannot be eliminated. The sexual elongation of the lifting chain and the single ring shall not exceed 5% of the original length. The lifting chain includes short ring chain, lifting chain, etc. Use 8 grade ordinary precision chain, welded lifting chain, non-standard lifting circular chain, and high-strength circular chain. The lifting chain is divided into M4, P5, S6, T8 and V10 series according to the mechanical properties of the finished chain. The grades are G30, G50, g80, G100, etc., and the materials are mainly carbon steel and stainless steel. Grade g80 and G100 lifting chains are made of high-quality synthetic steel (manganese steel, etc.) and applied to: strength correction chain, non correction chain, binding chain and hoist special chain; The surface is treated with natural color, polishing, blackening, painting, hot dipping and galvanizing, and the safety factor is 4 times, 5 times, 6 times and 2.5 times of the experimental load.
