It’s a spectacular order for Winkel GmbH: the component and system supplier from the Württemberg town of Illingen will be providing bearings and profiles for the construction of the World Trade Center Transportation Hub in New York. The Transportation Hub is being built on the site of the World Trade Center that was destroyed in 2001, together with four new skyscrapers. The Winkel bearings will be used in the retractable roof of the more than three billion dollar building.
The World Trade Center Transportation Hub was designed by Spanish star architect Santiago Calatrava and will provide transit connections to several train and subway lines as well as ferries and connect the various buildings of the emerging World Trade Center Complex with each other. The most striking feature of the building is its futuristic roof: it is made of glazed steel ribs soaring upwards in the shape of a V for more than 50 meters - modeled on the wings of a bird taking flight, according to Calatrava.
But that's not all. To let in sunlight, the entire roof can be opened up to ten meters in the middle - the bird is flapping its wings. In implementing this spectacular project, the project planners are relying on Winkel bearings and U-profiles. Built into the roof of the Transportation Hub, these components make up a robust and durable guide track system that stands up to the extreme loads during opening and closing of the rib structure. The Württemberg company delivered a total of 224 Winkel bearings with flange plates and 445 meters of U-profiles to New York. The Winkel bearings have a special anti-corrosion coating to protect them from the elements.
'Of course we are proud to play our part in such a historic and innovative project,' says Bernd Rudolph, responsible for the linear components at Winkel. 'The Winkel bearings in conjunction with the U-profiles are the ideal solution for this difficult task. They can withstand enormous static and dynamic loads, have a long service life and are easy to install and replace.' The World Trade Center Transportation Hub is supposed to be completed in 2014 – and until then, so Rudolph with a grin, 'we are teaching the bird to fly.'
