Gear units score at Wembley
Wembley is the world's largest covered stadium, and it cost more than one billion euros to build. The most innovative aspect of the engineering design is the retractable roof which, when open, lets the sun reach all corners of the field. If needed, the roof can close in just 15 minutes to protect the more than 90,000 spectators seated in the stadium from poor weather.
The fixed part of the roof is attached to one side of the arch soaring over the stadium. On the other side are seven sliding panels that can open and close high above the stadium, moving on roof trusses that are 160m long and supplied with tracks. The panels move at a speed of 30mm per second. Thirty-four Brevini planetary gear units make the seven panels slide perfectly into place. The panels each have a different shape and weight ranging from 63 to 330 tons each, for a total of 1200 tons.
After its work on stadiums in Amsterdam, Gelsenkirchen and Düsseldorf, Hollandia - the company which constructed the roof - chose Brevini products for Wembley Stadium. "It is a fine example of the level of cooperation that we have with our clients," explains Renato Brevini, the president and founder of Brevini Power Transmission. "It starts with the engineering project and continues with the production, arriving at a long-lasting partnership.
"Customer service is vital and one of our keys to success," he adds. "We serve our customers through an international network of 24 subsidiaries that are able to design projects and customised parts. This market approach ensures customer satisfaction in every phase of Brevini's relationship with the market."
