Record-Breaking Façade At Elevator Test Tower - continued
The work of experts from Taiyo Europe, who have provided textile architecture for renowned projects such as the Millennium Dome in London, San Francisco Airport, the German Pavilion at Expo Milan and the Mercedes-Benz-Arena in Stuttgart, is attracting great public interest in Rottweil.
Since the construction work is on schedule, the research operations at the tower are slated to begin in December 2016. In May 2017, the tower will also be opened to visitors.
The ThyssenKrupp Test Tower is 246 meters high and was formed using sliding formwork construction, which began in mid-April 2015. The crane grew along with it to an even greater height. The hook height begins at 90 meters and climbs to 259 meters.
The crane used on Rottweil’s Test Tower construction site was a 280 EC-H 12 Litronic from Liebherr. It was equipped with a powerful 110-kW hoist gear in order to achieve high hook speeds on account of the project’s required hook heights of up to 259 meters.
The 280 EC-H crane was mounted on a 500HC tower system. It consisted of individual tower elements measuring 5.8 meters in height. This tower system was selected in order to be able to ensure the largest possible scaling steps and to interrupt the sliding formwork construction as little as possible.
After a free-standing construction at 90 meters hook height, the crane was then gradually climbed up to its final height. There was a climbing unit mounted on the crane tower.
It consisted of the guide piece and an integrated hydraulic unit. The guide piece enclosed the actual crane tower, while the upper part of the crane used hydraulics to push the tower length upwards.
The guide piece was equipped with an appropriate high opening that made it possible to insert another tower element measuring 5.8 meters in height. This ‘climbed’ tower piece was subsequently bolted and the process began again. This process could take several days.
ThyssenKrupp started building the test tower with the general contractor Züblin in 2014. Among the leading-edge technologies that will be tested in Rottweil is the newest-generation elevator, the MULTI. Three of the twelve shafts in the new test facility are reserved for the MULTI system which is powered by maglev technology from the Transrapid and provides a number of advantages: The cable-free design means several cabs can be operated in a single shaft.
This increases passenger capacity per shaft by up to 50 percent and at the same time reduces the elevator footprint in a building by half. In addition, the elevators can move both sideways and vertically without height limitations, opening up completely new applications and architectural design possibilities.
