10mm lifting chains are widely used. Their standard load capacity is 3 tons, and the weight per meter is 2.15 kilograms. They are often used as important components of lifting tools, such as chain hoists and chain slings. They can also be used as transmission chains, for example, in scraper machines. After being made, the lifting chains are polished to their original color and then undergo surface treatment according to customer requirements. The diameter of the round steel of the chain is a shorthand for the specification of the chain, such as 6mm lifting chain, 8mm lifting chain, 10mm lifting chain, etc. For 20mm lifting chains, other parameters of the chain can be found in the parameter table. Grade 80 chains have a safety factor of 4 times and a weight load capacity of 2.5 times.
