ABSTRACT:
A portable support for a scaffold comprising first and second wheeled support members which are adapted to be placed on the building roof. The support members are interconnected by length adjustable braces to enable the distance between the support members to be varied. Handrails are also provided on the wheeled support members which extend therebetween to enable the entire assembly to be easily moved as a unit. The first support member has a plurality of upstanding posts secured thereto for selectively vertically receiving one end of an elongated scaffold support arm. The second support member has a pair of posts secured thereto and extending upwardly therefrom for receiving the scaffold support arm therebetween. The scaffold support arm is also length adjustable to enable the distance between the support members to be varied. An electric motor is mounted on the first support member and is operatively connected to an elongated axle which is secured to a pair of wheels on each of the support members and is adapted to drive the first and second support members as a unit along the building roof.
