8x36SW+FC Line Contacted Wire Rope
This configuration delivers the absolute pinnacle of passenger experience. It combines the supreme flexibility of the 36WS strands with the exceptional sound and vibration damping of a fiber core, resulting in a ride that is whisper-quiet and impossibly smooth. It is the definitive choice for elevators in world-class concert halls, five-star luxury hotels, and landmark skyscrapers where the elevator journey itself is a signature part of the building’s prestige.
8x36SW+IWR Line Contacted Wire Rope
This is the flagship engineering solution that makes the most ambitious architectural visions a reality. It provides the ultimate combination of fatigue life, maximum breaking strength, and near-zero constructional stretch. This makes it the mandatory specification for the main hoist ropes on the world’s fastest and tallest observation deck elevators, super-high-rise shuttle elevators, and other critical systems where absolute reliability and precision over extreme travel distances are paramount.
