Tunnel Roof
System description
The TUNNEL roof is a fixed construction, based on inward curved trusses that make a complete arch. The TUNNEL roof comes 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 meter bay sections. Each 5th section has to be stiffened by guy-wires or something simular.
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 Stage DEX stage with an Easy Frame B support frame or Probeam.
The arch connections are integrated in the stage floor, making it possible to use the weight of the stage act as
ballast for the roof.
The arched trusses have a keder profile on top to fit the optional canopy to the truss.
Due to the arched construction the TUNNEL roof is both
very compact and strong.
