MULTI is the first cable-less elevator developed by TK Elevator (formerly ThyssenKrupp Elevator). Rather than using cables to lift the elevator, MULTI uses linear motors. [1] As well as moving vertically between floors of a building, MULTI can also move horizontally through a floor of a building. MULTI is being tested at Rottweil Test Tower. [2] [3]
The system was installed inside a test tower in 2017. [4] As of 2024, there are no installations outside of testing sites.[ citation needed ]
