Geiger Engineers designed the mechanical systems that operate the new retractable roof on Arthur Ashe Stadium, the USTA's center court for the U.S. Open. The roof consists of two retractable panels each covering an opening nominally 232 feet wide. These two panels move along parallel tracks mounted on the north and south edges of the fixed roof. The tracks are curved to match the roof's slightly arched profile which has a maximum slope of 20 degrees. Wheeled bogies sitting on the parallel tracks support and move the retractable roof panels. Closing and opening of the roof is achieved with a pull-cable winch system with cables operating between the winch and roof panels. Four sets of brakes can lock the roof panels at any point in their travel.
