MAIN CHARACTERISTICS
Abrasion Resistant belts have an inside carcass of polyester (E) in wrap and polyamide (P) in weft. This gives the belt unique properties:
High resistance to breakage and impact
Great flexibility and light weight
Good disposition for trough
Ageing of carcass is nil
Low cost maintenance
High safety
Our
Abrasion Resistant belts are compliant with the internationally recognised
norms:

THICKNESS OF COVERS RECOMMENDED
Gravel, coal, limestone 3 + 1,5 mm.
Cutting stones 4 + 2 mm.
Debris and scoria 6 + 3 mm.
EDGES
Usually, our belts have sealed edges, but if required, we can manufacture them with cut edges.
ELONGATION UNDER STANDARD LOAD
To determine tension course of a belt, the technical conditions of the installation must be taken into account. As a guideline, the DIN 22.102/89 norm establishes the following values:
|
Minimum breaking Load |
Elongation under standard load |
|
200-
500 |
1,5

* The standard load is 10% of minimum breaking load.
