The Thyssenkrupp test tower in Rottweil ( Germany, state of Baden-Württemberg) is a 246 meter high elevator test tower for express and high-speed elevators. The tower, built by Thyssenkrupp Elevator from 2014 to 2017, offers the highest visitor platform in Germany at 232 meters and is the world's second-highest test tower for elevator systems. With the basement floors, which are used as a test environment for the elevator shafts, the shaft has a total length of 275.5 meters.
The tower has won numerous architectural, engineering and design awards and offers some unique selling points. So it is the world's first structure that can set itself in motion by a vibration pendulum inside the tower shaft itself. This simulates real wind loads. The shaft is covered with a special fiberglass textile along a spiral tube, which determines the actual outer shape of the tower. This makes the tower the tallest textile-clad building in the world.
