ABSTRACT:
A basic scaffolding tower assembly for building up, in modular fashion, a multi-level scaffolding system includes a pair of load-bearing tower panels spaced from and parallel to the building facade. The tower panels are joined together by a pair of landing channels extending perpendicularly to the building facade, thereby forming a generally rectangular tower structure. The landing channels support a work deck running parallel to the building facade, and the tower panels are spaced apart sufficiently to provide a drive-through passageway along the work deck wise enough for motorized construction equipment. Extension members carried by the landing channels extend inwardly towards the building facade and support, in cantilever fashon, a four foot or wider work deck immediately adjacent the facade. The tower assembly components are made of aluminum and are sufficiently robust to support twenty or more work levels.
