Go taller with KONE

A breakthrough from KONE, one of the leaders in the global elevator and escalator industry, will enable elevator travel heights to be increased to 1 kilometre, twice the distance feasible using existing technology.

Known as KONE UltraRope™, the breakthrough represents a completely new hoisting technology that eliminates the disadvantages of conventional steel rope and opens up a new world of possibilities in high-rise building design. Featuring a carbon fibre core and a unique high-friction coating, KONE UltraRope is extremely light and enables elevator energy consumption in high-rise buildings to be cut significantly.

The lower rope weight offered by KONE UltraRope translates into a dramatic reduction in the moving mass of an elevator, in other words, the weight of everything that moves when an elevator travels up or down, including the hoisting ropes, compensating ropes, counterweight, elevator car, and passenger load.

Due to the significant impact of ropes on the overall weight of this moving mass, the benefits of KONE UltraRope increase exponentially as travel distance grows.
KONE UltraRope is extremely strong and highly resistant to wear and abrasion. Elevator downtime caused by building sway is also reduced, as carbon fibre resonates at a completely different frequency to steel and most other building materials. KONE UltraRope also has an exceptionally long lifetime, at least twice that of conventional steel rope. Thanks to its special coating, lubrication is not required either.

"We are certain KONE UltraRope will revolutionise the elevator industry for the tallest segment of buildings across the globe,” says KONE’s President and CEO, Matti Alahuhta. His view is echoed by Antony Wood, Executive Director of the Council for Tall Buildings and Urban Habitat (CTBUH), who describes the new technology as “a breakthrough on one of the 'holy grail' limiting factors of tall buildings – that is, the height to which a single elevator could operate before the weight of the steel rope becomes unsupportable”.  Photo courtesy of KONE.
