German elevator manufacturer ThyssenKrupp has introduced the first fleet of cable-free cars that can also move sideways.
The system, dubbed MULTI, will allow multiple cabs to motor along a single, looping shaft. The cars move by magnetic levitation (the same technology behind some high-speed trains), rather than being pulled by the heavy steel ropes that limit how high skyscrapers can stretch. With MULTI, architects will be able to build spindly towers on small plots formerly deemed untenable for high-rises.
Magnetized, stainless steel shafts will be required for buildings utilizing multi, although they will be smaller than traditional elevator shafts because they will not require room for heavy steel ropes. The ropeless MULTI takes up half the shaft space to move the same number of people, albeit in more cabs.
