A premium elevator traction steel wire rope designed specifically for ultra-high-speed, ultra-high-rise elevators. Compared to the common 8-strand configuration, it features an additional strand, resulting in significant improvements in structural strength, crush resistance, and operational stability.
Relative to 8-strand ropes, the 9-strand design ensures more uniform wire distribution and superior roundness, allowing for a tighter fit with the traction sheave and resulting in reduced vibration and noise during operation.
The rope core itself is an independent steel wire rope that provides robust internal support for the nine outer strands. This imparts exceptional crush resistance and tensile strength to the entire rope, ensuring structural stability and resistance to flattening—even under the immense tensile loads caused by the self-weight of ultra-high-rise elevator systems.
