New elevator hoisting technology will allow buildings to rise up to 1 km

KONE, an innovative leader in the elevator and escalator industry, recently announced a new high-rise elevator technology that is set to break industry limits and enable future elevator travel heights of 1 km - twice the distance currently feasible. The KONE UltraRope(TM) is a completely new hoisting technology that eliminates the disadvantages of conventional steel rope and opens up a world of possibilities in high-rise building design - an important consideration as urbanization brings increasing numbers of people to cities.

Comprised of a carbon fiber core and a unique high-friction coating, KONE UltraRope is extremely light, meaning elevator energy consumption in high-rise buildings can be cut significantly. The drop in rope weight means a dramatic 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 (see image). Due to the significant impact of ropes on the overall weight of elevator moving masses, the benefits of KONE UltraRope increase exponentially as travel distance grows.

Urbanization is a key driver for the development of cities and the elevator industry. More than half of the world's population already live in urban areas, and the United Nations estimates that by 2050 seven out of every 10 people on the planet will be living in cities. Building upwards is seen as the sustainable urban solution, and the number of tall buildings built around the globe has increased rapidly in recent years. Increasingly, tall buildings are also growing taller.

Nearly 600 buildings of 200 meters or more are currently under construction or planned to be built over the next few years, according to the Council on Tall Buildings and Urban Habitat. While there are currently three buildings in the world that top the 500-meter mark, there are plans for 20 more such buildings to be built in coming years. Additionally, there are currently some 3,000 buildings in the world that could benefit from modernization with KONE UltraRope.
