ABSTRACT:
Embodiments of the present invention are directed to a fold-up scaffold system that includes multiple spaced vertical beams supported at one end on a floor of a building and scaffold sections extending across the vertical beams. The system also includes means at opposite ends of the scaffold sections for pivotally supporting the scaffold sections to the vertical beams and at least two air cylinders for each scaffold section connected between the scaffold sections and the vertical beams. In addition, each of the at least two air cylinders is adapted to be actuated between a lowered and a raised position, the scaffold sections being pivoted away from the vertical beams when the at least two air cylinders are actuated to the lowered position to provide a substantially horizontal surface and is positioned substantially vertically against the beam when the at least two air cylinders are actuated to the raised position.
