The three-ring chain:

The three-ring chain for mine cars is mainly used in coal mines and transportation. The materials are made of high-quality alloys that have been specially treated, and the strength grades include grade B and grade C. The chain manufacturing standards include ISO, DIN, BS, JIS, GB, etc., and the verification load is twice the working load. Strict quality control throughout the production process and strict implementation of quality intensity testing, so that our mining chain meets the use standards.
