    Abstract: Sectional scaffolding assemblies are widely used by craftsmen in the construction industry. Multiple levels of interlocking scaffolds are employed to reach high locations. The present invention is shown as a vertical hoisting pole or mast that is furnished with vertically-spaced clamp members located adjacent the lower end of the mast for coupling the mast to both an intermediate upright on an end frame of the scaffolding as well as to vertically-spaced rungs on the end frame. A pulley assembly is suspended from the top of the mast, and it includes a long rope acting with the pulley. One end of the rope is fitted with a loop that is adapted to be lowered over a top corner pin of the end frame. This loop carries an elongated push rod that has a hook formed on the free end thereof.
