F-Class® Chain

The F-Class chain FCC is a JDT designed and patented conveyor chain for mining applications. It consists of forged vertical links with JDT short studs and welded horizontal links. Due to the lower overall height of the vertical link, longer service lives can be achieved or the nominal size of the chain used can be increased, thus achieving better conveying performance.
