German manufacturer, Thyssenkrupp has announced the launch of Multi, a radically new elevator that promises shorter waiting times, greater capacity and lower space and energy requirements.
The system replaces the traditional rope and counterweight design with a linear motor that can move carriages vertically and horizontally. This motor was originally developed for maglev trains, but has been adapted for use in elevators.
The horizontal movement is possible because the Multi uses two shafts rather than the one-shaft-per-cabin layout of a traditional elevator.
The company says that with one cabin per shaft, traditional elevators take up more and more space as buildings increase in height. Multi consolidates multiple carriages into fewer shafts, which reduces the elevators’ footprint by up to 50% and increased passenger throughput by at least as much.
The cabins are controlled by a wireless data system and an algorithm that can direct cars to callers in a more efficient way.
The Multi system was unveiled on 22 June, at a 246m test tower in Rottweil in southwestern Germany. The first building to be fitted with the Multi will be OVG Real Estate’s East Side Tower building in Berlin.
