High Tensile DIN 22252-2 Mining Round Link Chains for Scraper Conveyors

High Tensile DIN 22252-2 Mining Round Link Chains for Scraper Conveyors

The mining round link chain is a core transmission and traction component in mining operations and heavy-duty mining equipment. It is widely compatible with key equipment such as scraper conveyors, transfer conveyors, crushers, and hoists, undertaking core tasks including material transportation and equipment traction. It serves as the “power link” for ensuring the continuous and efficient production of mines. Manufactured in strict compliance with the DIN22252 mining chain industry standard, it can be accurately matched with supporting components such as mining split-type chain connectors and mining flat-type chain connectors, which ensures the stability of connections and the safety of equipment operation, and meets the mining operation needs of different tonnages and under different working conditions.
