Benefits

Why industries choose steel cord conveyor belts

Operating tensions up to 10000 kN/m — only viable option beyond 2500 kN/m
Lower factor of safety (6.67 vs 10) — replace with smaller-rated belt for cost savings
Elongation under 0.25% — allows significantly smaller takeup lengths
Low elongation + high strength — longer centre distances between pulleys
Thinner carcass — smaller pulley diameters and reduced energy consumption
Higher rubber proportion — superior impact absorption for heavy individual pieces
Perfect troughing on deep idler sets — easier training and greater capacity
Thicker cover rubber for same rating — longer life than equivalent fabric belts
Splices achieve near 100% of belt rated strength and last as long as the belt
Repairable via hot or cold vulcanization — covers replaceable to fully rejuvenate
