Abstract: A method for manufacturing a modular starting gate. The modules making up the starting gate include a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. Each module is manufactured to precise tolerances using fixtures or jigs to achieve the desired tolerances. The door releasing module is coupled to the truss module. The truss module is raised mounted to the towing module and the wheel assembly module. A first stall divider module is attached to the truss module and a positioning fixture is used to properly align a second stall divider module relative to the first stall divider module. The second stall divider module is attached to the truss module. The positioning fixture is removed and the front and back gate modules are fastened to the stall divider modules.

Abstract: A modular starting gate having a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. The door releasing module includes a roll-bar having articulated members that are coupled to the front door module via a coupling bar and a turnbuckle adjuster. The roll-bar is coupled to the truss module via a bearing and includes a first section coupled to a second section via a U-joint. A rebound stop is coupled to the starting gate, wherein the rebound stop has a first portion mounted to the front door module which cooperates with a second portion coupled to the stall divider module.

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.
