Discover KONE UltraRope® – carbon-fiber elevator rope technology

KONE UltraRope® is an ultra-light, carbon-fiber hoisting rope that provides high-rise elevators with unrivalled eco-efficiency, reliability, and durability.

It eliminates the disadvantages of traditional steel elevator ropes – high energy consumption, rope elongation, large moving masses, and downtime caused by building sway – and enables tangible benefits for all new and existing tall buildings.

KONE UltraRope® is a well-proven technology, used in high-rise elevator projects for over 10 years, and is type-certified for all major elevator safety codes worldwide.

Superior carbon-fiber hoisting ropes for high-rise elevators

Lasts up to 3 times longer than steel rope

Carbon-fiber core with a highly wear-resistant coating delivers exceptional durability, offering superior fatigue and abrasion resistance.

Rope mass 80% lighter than steel rope

With around 80% less rope mass than conventional steel ropes, KONE UltraRope® significantly reduces the moving masses in the hoisting system. 

Maintenance-free

KONE UltraRope® stays strong and maintenance-free. Unlike traditional steel ropes, it doesn’t elongate, rust, or need lubrication, helping your elevators run reliably for years.

More resistant to building sway

With a higher natural frequency than steel ropes, KONE UltraRope® prevents overlap with the building’s natural frequency, increasing resistance to building sway.

Minimize maintenance, maximize uptime with KONE UltraRope®

LIFETIME ADVANTAGES

Three times the durability of steel rope

Unlike steel ropes, which rust, stretch, and require frequent lubrication and shortening, KONE UltraRope®’s carbon-fiber core with abrasion-resistant coating delivers up to 3× longer lifetime — typically 15 years before replacement. It provides more uptime over your building’s full lifecycle by eliminating the need for annual rope shortenings and traction sheave repairs.

With minimal maintenance requirements, KONE UltraRope® delivers an additional 162 days of uninterrupted operation over 25 years for a group of six elevators.

SWAY SOLUTION

Keep operating in any weather

Steel ropes often have natural frequencies that overlap with a building’s frequency, causing resonance that increases rope sway. This can affect elevator availability, as units may need to be taken out of service in windy conditions.

KONE UltraRope® has a significantly higher natural frequency that does not overlap with the building’s natural frequency, keeping elevators running reliably even in windy conditions.

SMALLER CARBON FOOTPRINT

Energy-efficient and sustainable

KONE UltraRope®, combined with KONE Advanced Destination Control System and energy management, can reduce total energy consumption on a typical office day by up to 30%.*

Third-party verified Environmental Product Declarations show that KONE high-rise elevators with KONE UltraRope® have an 11%* smaller lifecycle carbon footprint for 200 meters of travel and can contribute to LEED/BREEAM green building credits.

*Both figures are compared with a typical high-rise elevator using standard steel ropes.

STRENGTH WITHOUT THE WEIGHT

Less demand on building design

KONE UltraRope® uses a carbon-fiber core with high-friction coating, making it 80% lighter than steel ropes.

The reduced moving mass enables lower acceleration currents, less machine-room cooling, and smaller structural loads.

Frequently asked questions

  • KONE UltraRope lasts up to three times longer than traditional steel rope, thanks to its carbon-fiber core and highly wear-resistant coating. It offers superior resistance to fatigue and abrasion, helping extend service life and reduce downtime over the building lifecycle.

  • KONE UltraRope does not require lubrication at any point during its lifetime. Its composite material does not corrode or elongate, eliminating the need for lubrication and periodic rope shortening, and reducing overall maintenance requirements and downtime.

  • KONE UltraRope is around 80% lighter than conventional steel rope. This significantly reduces the moving mass in the hoisting system, improving efficiency and lowering structural loads.

  • KONE UltraRope has a higher natural frequency than steel ropes, which prevents overlap with a building’s natural frequency. This eliminates rope sway and helps maintain reliable elevator operation, even in windy conditions.

  • Yes. KONE UltraRope can reduce total energy consumption by up to 30% when combined with KONE advanced control and energy management systems. In addition, third-party verified Environmental Product Declarations show up to an 11% smaller lifecycle carbon footprint compared to elevators using standard steel ropes.

  • KONE UltraRope is designed for high-rise and supertall buildings, enabling significantly greater travel heights than conventional steel ropes. Its lightweight structure reduces rope mass and energy consumption, making it suitable for the next generation of tall building designs
