Elevator test tower

from Wikipedia, the free encyclopedia

A test tower for elevators (also: elevator test tower ; elevator research tower ) is a tower that is used as a functional building by an elevator manufacturer or mechanical engineering company on their premises for testing new elevator types and technologies, as well as elevator research. Analogous to the ever taller skyscrapers, telecommunication and observation towers, the elevator research towers are also getting higher and higher. The still possible height of new buildings depends not least on reliable and complex elevator systems as high-speed elevators over great heights and as distribution elevators over floor blocks, without which the ever higher record high buildings are not possible. This not only applies to passenger lifts, but increasingly also to goods lifts that have to be able to supply the many floors quickly with a high payload.

Test towers

Elevator manufacturer

In particular, the large elevator and mechanical engineering companies such as Otis , Schindler , Kone , Mitsubishi , Hyundai Elevator , Hitachi etc. operate such test towers at considerable heights.

thyssenkrupp test tower in Rottweil

The currently tallest elevator test tower is the thyssenkrupp test tower in China, which went into operation in 2018; thyssenkrupp does not give an exact name. Before that, it was the 246 m high thyssenkrupp test tower in Rottweil , which went into operation in December 2016 , also from thyssenkrupp Elevator . The towers replace the 213.5 meter high G1Tower from Hitachi. In December 2010, Hitachi completed a 172.6 meter research tower in Shanghai , which was the tallest elevator test tower in the People's Republic of China .

Component manufacturer

Elevator test towers are also in operation by elevator component manufacturers, such as the elevator sensor component manufacturer Cedes in Switzerland , which also carries out contract test series for other component manufacturers: In 2007, Cedes was for Hilti , a manufacturer of fastening systems, to research behavior and the improvement of mounting anchors for rail holder to the shaft walls operates.

Test facilities underground

No elevator test towers, but also elevator test systems with high lifting heights are those that are installed in former shafts of abandoned mines . The elevator manufacturer Kone operates such a system in Lohja ( Finland ) with a depth of 333 meters and thus achieves a higher lifting height than with the highest test tower.
