Lucas Oil Stadium

Completed 2008
Indianapolis, Indiana

Each of the two roof panels has two cable drums over the two outboard rails and has four cable drums over the three inboard rails, for a total of 16 cable drums per roof panel. Each cable drum is driven by four 7.5-horsepower motors for a total of 64 motors per roof panel.

The stadium includes an 88-foot tall movable glass wall, made up of six panels that open to provide a 214-foot-wide window in the end-zone wall. Each panel is by a traction drive system made up of two hardened steel wheels, each driven by a three-horsepower motor. The six wall panels move simultaneously between the open and closed position in four minutes.
