|ESSEN, Germany – On a rainy November day, ThyssenKrupp announced to the world the launch of a shiny new product, which, if all goes according to plan, will turn the world of tall building design upside down – and sideways.|
The few basic certainties designers have held about elevator design for 150 years – that there will be one cabin per straight vertical shaft; that there will be a motor on top of each shaft to pull the cable; and that there will be a counterweight going in the opposite direction of the cabin – have been upended.
ThyssenKrupp’s MULTI System will combine two technologies with which ThyssenKrupp made its way into the elevator market: linear-induction motors (now in use on the Accel Tapis Roulant system) and the capacity to control independent operation of multiple cabins in a single shaft, which has been applied since 2003 in the Twin system. The combination of these two technologies will allow multiple rope-less cabins to move in a single shaft and, the fact that the motor is “on” the cabin will allow the cabin to go vertically, horizontally and, potentially, diagonally.

|This technology will be available after 2016, when it will be tested at full scale on a 246-meter test tower being built for the purpose in Rottweil.|
Though obviously an important piece of proprietary technology, MULTI was announced at a press event many months before its commercial availability, because designers and developers will need time to understand and exploit the full possibilities afforded by this system.
