ABSTRACT:
A work scaffold system including a frame structure having spaced, parallel upper and lower horizontal track members upon which a pair of vertical column members may be horizontally moved. The vertical members have tracks for the vertical movement of worker cars. The structure supporting the horizontally and vertically movable worker cars are positioned in a desired location adjacent the face of a building by a truck crane or the like which is attached to the scaffold system by a hydraulically powered knuckle assembly attached between the crane head and the scaffold to provide control of both horizontal and vertical axes of rotation for proper attitude alignment of the scaffold.
