After three years of work, ThyssenKrupp, a company synonymous with elevators, is testing the Multi in a German tower and finalizing the safety certification. Zooming up, down, left, right, and diagonally the new elevator was just sold to a residential building under construction in Berlin, and is expected to be sold to other developers soon.
"Multi moves to-and-fro through exchangers, which you can think of as sophisticated railway switches that guide the cars. Bearings called "slings" mounted to every elevator car allow it to change direction—say, move to the left, or even go diagonally—while keeping the car level with the ground. “The cabin never moves during an exchange,” company CEO Patrick Bass says.
