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.

Further information

F - Class® Chain can be used in all AFC, BSL and roadway conveyors. There are the following advantages:

 

  • F - Class® Chains are characterized by their special shape of the vertical links. The new patented design with short studs prevents damage and failure due to kinking of links as a result of slack chain at the conveyor drive and reduces the risk of immersion of the vertical link into the flight bar.
  • By optimising the cross-sections, F - Class® Chains prevent operational stress peaks in the vertical links.
  • For a given nominal thickness the overall height of the chain can be reduced considerably. Our F - Class® Type ”W” is a genuine alternative to Flat- and Combi-chains. Without any change, all other conveyor elements may be further used. Friction between the chain and pan line is drastically reduced. A sawing behavior of the chain, which can result in grooves in the pans, is avoided as well as friction martensite at the chain legs. Experience shows that power demand and current-consumption are lower.
  • For a given height, a greater nominal thickness of the chain is possible. Thus, the following objectives can be achieved: increased capacity, extension of the conveyor, increase of operational safety and increase of service life. Existing pan lines can be used further. The favourable charging behaviour of low profile conveyors is retained. For this, we offer you the type of series ”C“ and ”A”.
