Compact Link Mining Chain |
|
|
|
|
Parsons Compact Link mining chain was first manufactured in 1985
utilising 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 larger compact chains are formed and
laced together with specially designed machinery to ensure continuous
and consistently formed chain.
Parsons Compact mining chain may be manufactured to Xtra and DIN
quality grades with dimensions generally in accordance with DIN
22255:2001.
