ABSTRACT:
A truss system for supporting stage lights or other components having a strong rigid frame and a vertically adjustable deck from which the components are highly accessible. The system may be connected to other systems either collinearly or in angled configurations. Caster legs are retractable and the deck is vertically adjustable in response to the components used and/or the geometry of the venue. The deck is cushioned against shock and vibration by interposing coiled cable shocks between the frame and deck.
