  • Publication number: 20240018793
    Abstract: A mobile stage configured for reconfiguration between trailered and deployed configurations featuring a hydraulic ram with a lifting carriage for lifting towers and tower mast caps into place to raise a stage roof above a stage floor. Additional features include slide-out speaker wings which provide additional structural stability when stored within the stage structure, spanner beams that are folded flat inside the roof when the trailer is in the enclosed traveling position, and which can span the entire roof, meaning there are no areas of the roof where lights or equipment cannot be hung. It also creates a 1?×1? grid system to be used for both the hanging of equipment and the easy calculation of the load on each section of the roof.
