Retractable Roof: Commerzbank-Arena Frankfurt

The interior roof consists of a folded diaphragm hanging on a steel rope construction, which can be opened and closed within a short time. Opening and closing is done fully automatic by simply pressing a button. First the diaphragm is unfolded with winches. Close to the end position the diaphragm end points are connected to hydraulic cylinders, which move them into the final position. Opening the roof is done in reverse order.

The Commerzbank arena in Frankfurt (former Waldstation) is one of the venues of the FIFA soccer world championship 2006 in Germany.
