Far from the big cities in which skyscrapers predominate, huge towers are erected that do not usually fit into the landscape. These lonely and imposing structures can arouse curiosity or confuse those who do not know what their function is or what is inside. Fortunately, they do not hide any mystery: These are structures designed to put elevators to the test.
Vertical testing laboratories
It is not common to find this type of test tower, in the world there are little more than 30, but when they appear on the horizon, they completely dominate it thanks to their height. Most of them are in Asian countries and have been built in industrial estates or sparsely populated areas by the very companies that manufacture and develop elevators.
The world’s largest test tower, named H1 Tower, is located in the outskirts of Guangzhou, China. It was built by Hitachi and is 273 meters high. In Rottweil, Germany, it is located one of ThyssenKrupp’s elevator laboratories, which although it is not the highest (246 m), stands out for being the testing epicenter of an innovative wireless elevator and for having a viewpoint open to the public.
The elevator manufacturers club is made up of well-known names such as Hyundai Elevator y Mitsubishi Electric, but there are also companies that are heavyweights in the sector such as the American Otis, the Greek Kleemann, the Finnish Kone and the
Swedish Schindler, the latter with test towers in Shanghai, Lucerne and Sevilla.
But it’s not just about private companies. In 2013 the University of Extremadura announced the construction of a test tower over 40 meters high and 13 floors on the Badajoz campus. Unfortunately the project has experienced financing problems that have prevented it from being completed. However, the UEx vertical transport laboratory is expected to go live in 2022.
Test towers play a key role in testing elevators. These are designed to assess the limits of stress and fatigue of the cabs, traction machinery, ropes, guides, and parachute and speed reduction systems in a controlled environment. Speed tests are also carried out, which require a minimum height to reach the necessary acceleration.
