Lift Elevator Ropes
No other application of steel wire ropes demands such close manufacturing tolerances and such high quality in Materials as the elevator industry. No other industry demands such high safety factors.
our products are always striving to improve on these standards and offer a complete range of elevator/lift ropes. These lift elevator wire ropes as lifting equipment are specially designed to meet the requirements for elevator industries. We not only act as suppliers but also work closely with our customers in their endeavor to deliver the highest quality standards, better durability and longer service life.
Fatigue tests arid on load tests on our lift wire ropes / elevator wire ropes have demonstrated by our principals that they are far superior than the comparative industry standards.
Our products operate a Quality System in accordance with ISO 9001 and have complete control of manufacturing process from wire to the finished rope.
