Hekla Tower, the latest skyscraper in Paris’ “La Defense” district, will include 12 of thyssenkrupp’s unique TWIN elevators, as well as another 12 conventional elevators and escalators. The elevator system features two cars operating independently in one shaft, making efficient use of available space while transporting up to 40% more passengers than conventional elevators. Each elevator has its own major mechanical and electrical components, but shares the same guide rails and landing doors in a single elevator shaft.
