ABSTRACT OF THE DISCLOSURE A plurality of scaffolds stacked one above the other on a support and each scaffold supported on two laterally spaced self-locking scaffold brackets attached to the supports by load-activated locks. A hoisting mechanism is selectively connected to the scaffolds in such a way as to lift each of the scaffolds up sequentially into its final position. Mechanical jacks connected to the load activated locks are used for final small adjustment of the positions of the scaffolds. The jacks are disabled without removing them during the time that the scaffolds are being moved up or down.
