26 PORTABLE SUPPORT SYSTEM FOR SUSPENDING PERSONS FROM BUILDINGS ABSTRACT OF THE DISCLOSURE A portable support system for use on the roof of a building to support an object and/or person therefrom. The system is arranged to be readily rolled to a desired position adjacent the edge of the roof and includes two wheeled frame assemblies and a collapsible/extendable boom assembly. The boom assembly comprising pivotable sections arranged to be extended from a compact orientation to an extended orientation and vice versa. The frame assemblies are arranged for connection to respective portions of the boom assembly. When the boom assembly is in the compact orientation the frame assemblies are closely connected together via plural connecting members to form a compact cart. The frame assemblies each include a pair of spaced wheels which can pivot in any direction to enable the cart to be readily wheeled to a position at the edge of the roof. The frame assemblies are then disconnected from the connecting members, and the boom sections extended so that the frame assemblies are spaced further apart for stability. A portion of the boom assembly extends over the edge of the roof to support a person/ object therefrom. When the system is in position supporting the person/object the wheels are locked into an orientation so that they may only roll in directions transverse to the axis of the extended boom so that the system may roll along the edge of the roof, if desired.
