KONE UltraRope


Kone People Flow Center Kone Ultra Rope 

Kone UltraRope is a cable designed specifically for the ever-growing elevator shaft. The logistics involved in building taller building are often the primary setback for construction and architectural firms. High-rise elevator components operate under highly demanding conditions, making durability the biggest challenge. Such components are subject to severe stresses such as building sway, which can put them out of service on windy days. It’s unfortunate to think of all the skyscrapers that never left the drawing board due to engineering limitations, especially considering the plethora of new material and structural innovations.


The UltraRope is equipped with a carbon fiber core giving it its lightweight properties. These lighter cables would reduce energy consumption in traditional buildings by 15% and decrease the force required for moving masses by 60%. And in this increasingly vertical world, buildings will only get taller, allowing for up to a 45% decrease in energy consumption and 90% for moving masses. Additionally, the cable is layered with a high friction coat that allows for double the lifespan that is currently feasible with traditional steel elevator cables.
Kone proposes a thoughtful solution to the high-rise problem. Though carbon fiber cables are merely a stepping stone into the vast array of intricate problems associated with designing taller structures: supporting the load at the base, preventing the effects of wind, etc. For now, it seems we can only solve one problem at a time, and set a foundation for the skyscrapers of tomorrow.

    This new elevator “UltraRope” is a very interesting creation for buildings. Not only are they stronger and lightweight, but they make moving elevator cars easier and they require less energy. These seem useful, but it also seems as if there may be some flaws. The cost of production and materials for these “ropes” may be very expensive and created an added cost in building production, which may or may not pay off as a future investment.
    You bring up a good point in the amount of buildings that never get off the drawing board because of these kind of issues. Would these new elevator cables be enough to bring more buildings to life? Also, could these cables be places in already made buildings to save energy? This could be useful in current skyscrapers and facilities that use elevators every day by dropping their energy prices dramatically. It seems as if this material could be put to use in other forms other than just elevator cables as well. Limitations for this material and these cables could be expanded in more research and development. It will be interesting to see if buildings start using these cables and if any new buildings that you may not have seen without them are truly put to the test in the real world and not just the drawing board.
