ABSTRACT:
A portable scaffold has a frame with a pair of spaced apart, longitudinal members which are essentially parallel to the direction of forward travel of the frame. The frame has a plurality of wheel assemblies attached to each corner thereof with pneumatic tires thereon so that the frame can travel over public roads or the like. A scaffold structure is attached to the longitudinal members by an attachment structure which will telescope between a narrow length which is within legal limits for highway travel. Similarly, transverse members connecting the longitudinal frame members together are provided which also can be telescoped between a narrow distance for legal travel down a public highway and a wider distance which provides the necessary base of a platform for the scaffold so that the scaffold can extend higher than would otherwise be permissible if the portable platform could not be widened.
