The Multi is the first ropeless lift, built using the same magnetic levitation technology used in Japan's bullet train and proposed for the Hyperloop. In the same way the train slides along a track horizontally, the lift travels both vertically, horizontally and diagonally around a building riding an electromagnetic field, a system known as a linear drive. “If you can run a 500-tonne train on magnets at 500km/h you should be able to elevate a cabin of 500 kilograms or 1,000 kilograms at a speed of five metres per second,” Schierenbeck said.
Standard rope and pulley lifts today can only rise to a maximum of around 500 metres. But, skyscrapers are much taller and they are only getting higher. So far, the solution to this has been to build multiple elevators and therefore more shafts but the space required can cost a building up to 40 per cent of highly valuable floor space. “This cannot go on forever,” Schierenbeck said. While the Multi can cost three to five times more than a standard lift system, Schierenbeck claims saving that much space in a central downtown building, for example, is “definitely overcompensating the price of the product.”
