2013 Tall Building Innovation Award

“This is finally 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 over that height. So it is not an exaggeration to say that this is revolutionary. However, it is not just the enablement of greater height that is beneficial – the greater energy and material efficiencies are of equal value.”

KONE UltraRope

Comprised of a carbon fiber core and an epoxy-based high-friction coating, KONE UltraRope is extremely light, meaning elevator energy consumption and machine room size in high-rise buildings can be cut significantly. The drop in rope weight means a reduction in elevator moving masses – 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. Currently, elevators are limited to a single-shaft height of  500 meters, the point at which the mass and thickness of steel rope makes further height impractical. With UltraRope, elevators can travel up to 1,000 meters (1 kilometer) without the need for transfer lobbies.
