A metal framework used to hang lighting, audio, or visual equipment above a stage or event floor.
Trusses are the primary structure for suspending production equipment in events. They are assembled from interlocking aluminium sections and lifted into position using motors or chain hoists. Trusses carry the weight of lighting fixtures, PA speakers, LED screens, and draping. The span, weight capacity, and height of the truss must be engineered to match the equipment load and the venue's structural capacity.
