Products — Crane Ropes
Endurance Dyform 34LR/PI/MAX product Benefits and Features
Breaking force Strongest of all ropes in the rotation-resistant product range — confirmed by Bridon’s Powercheck process.
Resistance to rotation Greatest resistance to rotation of all ropes in the rotation-resistant product range — confirmed by Bridon’s unique
Twistcheck testing program.
Resistance to bending fatigue Longer bend-fatigue life when compared with conventional rotation-resistant ropes — confirmed by laboratory testing and extensive field experience.
Resistance to crushing Excellent resistance to crushing and abrasion due to the rope’s compact design and the Dyform strands — recommended when multi-layer spooling is involved.
Reduced elongation Increased steel content and the Dyform process minimize elongation.
Reduced sheave wear Smooth outer Dyform surface decreases the amount of sheave wear.
Long service life Exceptional performance means less down time and more work time.
Optional plastic coating of IWRC IWRC coating extends fatigue life, improves structural stability, and resists corrosion.
