So What’s New about GEN 2 ? Revolutionary New Coated Steel Belts
FLAT COATED STEEL BELT Conventional Steel Rope Flat Coated Steel Belt Quiet & Strong“Green” & Flexible Less stretch
300 Grams/ meter 220 Grams/ meter Product Overview Coated Steel Belt
(HALT) Highly Accelerated Life Testing –indicates belts will last 3 X the life of hoist ropes under similar conditions Product Overview Safety and Testing High Cycle Fatigue - - Used by Pratt & Whitney - tested for 120 million cycles without failure
Simulated Fire in the hoistway Melted and burned the Polyurethane coating The damaged Coated Steel Belt was able to: Product Overview Safety and Testing -hold the load -maintain traction -even during an emergency stop
GeN2 Comfort – SPECIAL FEATURES “Pulse” electronic monitoring Continuously monitoring the belt’s steel cords 24h/7d Reducing the downtime Increasing the reliability of the inspection Otis ‘Pulse’ system monitors belt cords integrity 24h/7d.
