Round link steel chains have become a proven standard in mining and have developed in the coal mining industry along with Long wall mining, a highly effective means of extraction, since the 1960s. Armoured face conveyors require a chain that will run over long distances and offer flexibility in operation. The main standard is covered by DIN 22252.
The standard applies to round steel link chains used as means of traction in chain conveyors, bucket elevators and winning equipment, primarily in mining, in particular in face conveying as short chains strands with shackle type connectors in accordance with DIN 22253 and scraper bars in accordance with DIN …
