"Rock Belt™" and "Monoply Belt™" Impact-resistant conveyor belts

Conveyor belt for transporting heavy loads with excellent impact resistance

Rock Belt™ and Monoply Belt™ were developed for conveyor lines with high impact properties. The core canvas has a special woven structure, and both the cover rubber and the core are designed with impact in mind. This belt is best suited for lines with high impact force and short life with conventional products.

"Rock Belt™" and "Monoply Belt™" Impact-resistant conveyor belts


Excellent cut resistance, abrasion resistance, impact resistance, and bite resistance, and long service life due to less core damage
The belt is ideal for replacing conveyor belts that are subjected to high impact and have a short life span.
Monoply belts are 1-ply (for small to medium impact applications), large block belts are 2-ply (for large block impact applications)


[Features of interlining canvas]
This special canvas has a structure in which the warp and weft yarns are combined above and below the warp, and the warp and weft yarns are woven together with a knotted thread. It is highly flexible, and the warp and weft yarns individually receive and absorb stresses applied to the belt.
Therefore, it has excellent impact and bite resistance.
