Creating Solutions

Guardian® is constructed for above ground coal handling in power generation and coal preparation plants where leaching agents and dust suppressants can be major influences on belt deterioration. Fenner Dunlop offers two compounds specifically formulated to address these problems. GUARDIAN and GUARDIAN AR are compounded and designed to reduce conveying problems related to dust suppressants, as well as, to counter the negative effects of leaching agents, such as durometer creep and plasticizer extraction.

Balanced Construction

To further enhance performance, Guardian® is constructed with a minimum 3/32″ bottom cover to insure a more balanced construction, greatly minimizing the occurrence of cupping and curling in power generating and coal prep plant applications. The result is better tracking and extended conveyor belt life.

Constructed to Last


Guardian® insures the original integrity of the belt by utilizing either Fenner Dunlop’s Royalon® or Plylok Supreme® carcasses*. Both constructions are manufactured from polyester warp and nylon fill yarns which yield lower stretch, improved tracking and reduced downtime due to belt break-in and re-splicing. The result is:

  • Unsurpassed resistance to abrasion, gouging and tearing.
  • Excellent load support
  • Superior fastener retention

*UsFlex® straight-warp carcass available upon request.

Guardian® is available in 110 PIW, 125 PIW, 150 PIW, 200 PIW, 250 PIW and 300 PIW per ply constructions.
