ThyssenKrupp has announced that they have found their first customer to implement their cutting-edge “MULTI” elevator system that is the first ever not to use a rope while also being able to move both horizontally and vertically. This system will be installed in Berlin and on a newly built tower of 245 meters of height that is set to become a landmark of the historic German city. The MULTI elevators are so groundbreaking that they are expected to change the way engineers and architects design large buildings, as well as introduce dramatic improvements to the current time that is wasted on offices, hospitals, and other large structures in the world to wait for a free elevator cabin.
ThyssenKrupp’s estimations are that if we continue to use the current elevator systems that have been mostly unchanged since their inception 160 years ago, the situation around the globe will get worse and worse. Indicatively, the number of buildings that rise above 200 meters has tripled since 2000, while the total world population that is going to be living in a city will be approximately 70% by the end of 2050 compared to the 50% that it currently is. This is why they were determined to develop something really innovative and game-changing, so they have ditched the ropes and classic shafts and turned to using direct drive motors and magnetic levitation guiding rails. This makes it possible for the shafts to travel horizontally and vertically, take 90-degree turns, move super-fast (18 m/sec), and be even safer while doing so.
In numbers, ThyssenKrupp promises a maximum waiting time of 30 seconds in any usage case scenario, a reduction of carbon footprint by about 60% compared to the standard systems used right now, a reduction of the cabin weight by 50% which obviously makes the system more energy efficient, and a significantly less space for the shaft requirement (about 50%). Of course, increasing the passenger throughput and speeding up the personnel traffic inside a multi-storey office will have extreme cost-efficiency benefits for the company that uses the MULTI. The obvious drawback is the cost of implementing MULTI that is currently at five times the cost of a conventional elevator system. While the return of investment period isn’t too long, still, it is not expected that MULTI will flood the market right away because of the high initial cost.
Currently, ThyssenKrupp is feverishly preparing their own testing tower in parallel with their first project in Berlin. The tower is almost completed standing at a height of 245 and will be made open to the public as a viewing tower. Representatives of the company estimate that their Berlin-based customer will have their MULTI system up and running by the end of 2019.
