Abstract
A staging system includes vertical posts each with rack gears disposed along their lengths. A self-propelled truss-support collar with a motor and pinion gear can climb up and down the vertical post by engaging the rack gear. A battery inside the collar provides electrical power to the motor so AC utility power is not needed. The collar provides an anchoring plate for attachment and support of horizontal staging trusses for assembly on the ground and self-elevation overhead. A protective track cover tape in the vertical post hides the rack gear from view. A threading roller in the collar routes the protective track cover tape around the pinion gear so it can engage the rack gear.
