ABSTRACT:
A chain of end support sections are foldably linked together and hang vertically from either side of a horizontal support beam. The beam is attached to a pair of suspension cables through two motorized grip hoists rigidly attached to the beam and the cables then hang downwardly along the chains of end support sections to the ground. Work platforms extend horizontally between the end support sections and can move vertically independently of the end support sections. Means are provided for selectively attaching the ends of any work platform to the cables or the end support sections thereby enabling the independent movement of the end support sections and the work platforms during erection and disassembly of the scaffold system.
