ABSTRACT:
A portable stage, transportable in a stacked configuration on a conventional truck trailer, has two modular units manually or vehicularly positionable side-by-side to define the platform of the stage. The platform of one unit is laterally and angularly relocatable relative to the supporting frame to position it contactingly adjacent the platform of the other unit. A plurality of carts, nestable as pairs intermediate the stacked units during transport, are deployed to convey the equipment used on the stage from a source or depot to the assembled stage and return. A pair of ramps serve multiple functions of loading and unloading the units and the carts and are configured to be anchored to different load bearing receiving elements. A specifically configured detachably attached yoke permits turning of pivotally mounted paired wheel trucks while positioning a unit to assemble or disassemble the stage. The units may include detachably attached platform extensions to increase the length and foldable platform sides to increase the width. A manually vertically locatable landing is disposed at one end of a unit. Raceways beneath at least one platform and access holes in the platform provide for routing of power cables and other electrical conduits to equipment to be used on the stage. Wheel chocks, interacting with opposed pairs of wheels of the wheel trucks, positionally stabilize each of the wheel trucks during transport. Rotatably mounted extendable jacks assist in supporting each of the units of the assembled stage.
