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.

Un système d'échafaudage inclut des poteaux verticaux dotés chacun d'engrenages à crémaillère disposés sur leur longueur. Un collier de bâti-support autotracté doté d'un moteur et d'un engrenage à pignons peut monter et descendre le long du poteau vertical à l'aide de l'engrenage à crémaillère. Une batterie dans le collier fournit une alimentation électrique au moteur de manière que le courant alternatif ne soit pas nécessaire. Le collier sert de plaque d'ancrage pour la fixation et le support des bâtis d'échafaudage horizontaux pour la structure au sol et l'auto- élévation en hauteur. Un ruban de recouvrement du rail de sécurité sur le poteau vertical masque l'engrenage à crémaillère. Un cylindre à fileter dans le collier guide le ruban de recouvrement du rail de sécurité autour de l'engrenage à pignons pour qu'il puisse entraîner l'engrenage à crémaillère.
