Abstract
A convertible stadium includes a playing field, a seating area, a stationary roof structure and a large, heavy roof panel mounted for movement with respect to the stationary roof structure, A plurality of cable drums are mounted for movement together with the roof panel. Each cable drum has at least one cable wound thereabout. The cable is secured to the stationary roof structure and is payable from the respective cable drum. The system is designed so as to minimize movement between the cable and the roof panel, so there will be no possibility of frictional engagement therebetween.
