9×25F-IWRC

This is currently one of the most structurally complex and high-performance elevator wire rope models available. Building upon the 9x21F design, it incorporates an increased number of wires and utilizes a Filler (F) construction, making it specifically engineered for ultra-high-speed, super-tall elevator systems.

The Filler (F) construction significantly improves load distribution among the wires and reduces internal friction by adding internal filler wires. Combined with a 9-strand design, this configuration achieves industry-leading levels of both bending fatigue life and wear resistance during repeated operation over the traction sheave.

Thanks to the dual advantages of a compact filler structure and an Independent Wire Rope Core (IWRC), the rope boasts exceptionally high breaking strength. Furthermore, rigorous pre-stretching treatment minimizes both permanent and elastic elongation, ensuring precise leveling accuracy across the elevator's entire travel range.
