- Variable stage depth
- Compact and strong
- Extra options available
The Tunnel Roof is a fixed construction, based on inward-curving trusses that form a complete arch. The Tunnel Roof is available in two sizes:
12 m stage width combined with an arch 6 m height, or a 16 m stage width combined with an arch of 8 m height. The depth of the stage can be varied in 2 or 3 m bay sections. Each 5th section must be stiffened by guy-wires or similar support method. There is no limit to the depth of the stage.
Special adapters provide a connection between the stage floor and the truss arches. The Tunnel Roof combines very well with a StageDex stage as well as with an EasyFrame B support frame or Probeam. The arch connections are integrated in the stage floor, making it possible to use the weight of the stage as ballast for the roof. The arched trusses have a keder profile on top for fitting an optional canopy. Due to the arched construction, the Tunnel Roof is both very compact and strong.

Our experiences with this new ProLyft system are really positive. Rigging and outlining line-array systems is now very fast and accurate. Furthermore, the installing teams we’re a pleasure to work with.Arnold van Duijn Chief Operational Services, Concertgebouw Amsterdam
