ABSTRACT:
A pedestal scaffold type having a base member, a telescopic mast mounted vertically on the base member and a work cage mounted in cantilever manner from the upper end of the mast. The majority of the nested tubular mast sections are of rectangular cross-section and are formed of thin-walled sheet aluminum with rounded corners and vertical stiffening ribs on each side thereof extending the height thereof. Plastic slide blocks at the inner corners of the upper end and at the outer corners of the lower end of the mast section distribute the forces between the sections to relatively large areas of the aluminum sheet which forms the mast sections.
