Compact Link Mining Chain Compact Link mining chain utilises a forged vertical link This configuration has been developed in all sizes up to 48mm and has significant advantages over a flattened wrought vertical link. Parsons Mining Chain' S larger compact chains are formed and laced together with specially designed machinery to ensure continuous and consistently formed chain.
