(1) Mining Chains Mining chains developed for underground mining environments are used as transmission components for scraper conveyors and stage loaders. In accordance with the operating requirements of conveyors and stage loaders under different working conditions, we can design and produce various types of products, including round link chains (Grade C/D), compact chains, ultra-flat chains, etc., providing users with highly reliable products throughout their life cycle. (2) Mining Connecting Links Mining connecting links consist of left and right half links and a fixing pin, and are used for connecting mining chains. There are two main types: flat connecting links and vertical connecting links, featuring high strength, strong impact resistance and long service life. Flat connecting links can be used as either vertical links or horizontal links, while vertical connecting links can only be used as vertical links.
