Abstract
A multi-level construction scaffold comprises a pair of H-shaped end frames spaced by horizontal guard rails. The guard rails are pivotally connected at opposed ends thereof to the end frame members, thereby allowing the guard rails to pivot in parallel when one of the frame member is lifted relative to the other. Each end frame includes a pair of uprights interconnected by a horizontal platform support located at a distance below the guard rails engaged with the end frames. In this way, the safety guard rails of a next level to be erected can be installed directly from the underlying level.
