High Performance Actuation and Control of a Moving Roof

Download Case Study

Trusses are supported by the end arms and set into precise motion by electric actuators which form a structural yet moveable part of the roof.

The ends of each truss are supported by a wheeled carriage or ‘bogie’ which moves along a track positioned on the fixed roof.

Accuracy of Movement

Moog supplied high performance brushless servo motors, electric actuators, servo drives, servo controllers, and worked with Fairfield Controls to deliver the supervisory and data acquisition (SCADA) System to deliver 150 axis of control.

Service and Support

Global engineering, service and support is provided for the lifetime of the roof, and ensures that during championships, a full range of spares is available within 2 hours.

Technology Flexibility

The use of electric motion control ensures future operational requirements can be met, such as the addition of sun shade mode to remove shadow lines on the pitch.

Team Player

During the build and since the commissioning of the roof, Moog continues to collaborate efficiently with the contractors involved in the project.


Moog engineers continue to support and improve the operational efficiency of the roof ensuring Engineers are in situ for regular testing and during the championships.
