Thyssenkrupp Elevator ( spelling thyssenkrupp Elevator , formerly ThyssenKrupp Elevator ), headquartered in Essen, is one of the world's largest manufacturers of elevator systems . The product range includes passenger and freight elevators, escalators and moving walks, passenger boarding bridges, stair and platform lifts.
history
The company's origins lie in a small workshop founded by master locksmith Heinrich Conrad Ernst Eggers in Hamburg in 1865 , which Rheinstahl took over as Stahlbau Eggers in 1952 . In 1955 the Eggers company acquired the Hamburg-based company for elevators and escalators Kehrhahn , which was founded in 1882 as the Wimmel & Landgraf machine tool factory, and has been operating as Rheinstahl Eggers-Kehrhahn GmbH since 1957 . In 1973 the elevator division of the Stuttgart company R. Stahl AG and the Hamburg company Rheinstahl Eggers-Kehrhahn were integrated and in the same year a new large production facility was built in Neuhausen on the Fildern near Stuttgart. In the course of the takeover of Rheinstahl by August Thyssen-Hütte AG, the company name was changed to Thyssen Aufzüge GmbH in 1974 and finally to thyssenkrupp Elevator AG in 1999 through the merger with Friedrich Krupp AG .
According to the company, the most important acquisition in Germany took place in 1984 with the takeover of MAN elevator construction . In the following years the focus was on the internationalization of the company. With the participation in Northern Elevator Holding Ltd. Established a foothold in Canada in Toronto , before further establishing itself in North America. In 1991 a new escalator factory was built in Norte, Spain. In 1995, thyssenkrupp Elevator China was founded with a special plant in Zhongshan . With the acquisition of Dover Elevators, the market leader in hydraulic elevators in North America, in 1998 the company becomes the third largest elevator manufacturer in the world. In 2000 the company is transformed into an independent stock corporation. Acquisitions of businesses in South America and further expansion in Asia follow in the 2000s.
In 2007 the EU Commission imposed a fine of 992 million euros ( elevator and escalator cartel ) on five major elevator manufacturers, including ThyssenKrupp Elevator . The companies had agreed on prices and thus violated antitrust law. ThyssenKrupp Elevator had to pay 479.7 million euros, Otis 225 million, Kone 142 million, Schindler 143.7 million and a Mitsubishi subsidiary 1.8 million euros. This was the highest penalty that the EU Commission had imposed until then.
On February 27, 2020 Thyssenkrupp sold its elevator division for 17.2 billion euros to a consortium led by Advent International , Cinven and the RAG Foundation .
Company profile
The annual turnover in the 2014/2015 financial year was 7.2 billion euros. ThyssenKrupp Elevator employs more than 50,000 people.
Multi-car elevators
TWIN
ThyssenKrupp AG has been using elevators with otherwise conventional traction sheave technology since 2003, with two cabins operating in the same shaft. These are now being tried out in the test tower . The lower cabin is carried by suspension cables that run past the upper cabin. A destination selection control means that the host computer knows the start and destination of each journey before the journey begins; Collisions are excluded in the control. Compared to two elevator systems on top of each other in the same shaft, the system has the advantage that there is no rigid border that the cars cannot cross. By moving the cabins into a deeper shaft pit or raised shaft head, it is possible that both cabs can approach all floors. This is supposed to save 65% of the time.
MULTI
The company describes the Thyssenkrupp Multi as a “combination of Transrapid and Paternoster ”: The cabs are to be driven by linear motors instead of ropes . This means that several cars can be moved with high acceleration forces in one shaft. The cabins can also be diverted into horizontal tunnels . This enables circular operation like a paternoster and the system allows horizontal and vertical development side by side. As a result, the space required for lifts can be reduced, the shaft height is independent of the technical limit with the cable length of currently approx. 800 m and new architectural possibilities open up. The system is currently being tested in the Rottweiler test tower. It has not yet been approved for passenger transport. The first usable system is to be installed in the Edge East Side Tower in Berlin.
Test towers
In 2017, Thyssenkrupp Elevator opened a 246-meter-high tower called the thyssenkrupp test tower in the Berner Feld industrial estate in Rottweiler . The construction is used for testing and certification of high-speed elevators . The world's first ropeless elevator is also being developed here. The design of the tower comes from the architect Helmut Jahn . A public visitor platform at a height of 232 meters is the highest visitor platform in Germany.
Thyssenkrupp opened the currently tallest test tower with a height of 248 meters in China in March 2018. The completion of a 128 meter high test tower in Atlanta , USA, is scheduled for 2021.
