Abstract

An enhanced safety scaffold assembly (10) is provided including end frames (12,14) interconnected by means of cross-tie structure (18,20). The end frames (12,14) include ledgers (36) located a safety distance (38) of at least about thirty inches below the upper ends (26b,28b) of the standards (26,28), and are free of additional ledgers within the safety distance. A platform (16) is supported by the ledgers (36), and guardrail assemblies (22,24) extend between opposed standards (26,28). In this way, the platform (16) is located well below the upper ends (26b,28b) of the standards (26,28) in accordance with existing safety regulations, and placement of a platform (16) in an unsafe, elevated position is precluded. The assemblies of the invention may be constructed in a variety of ways to include optional leveling units (58), ladders (44), outriggers (134) and supplemental work platforms (144).
