  • Patent number: 9556626
    Abstract: An apparatus and method for raising a self-jacking scaffold system including extending a jacking screw and jacking screw bracket axially upward, connecting a jacking screw bracket to an overhead tank bracket for a plurality of scaffold sections coupled to a jacking assembly, detaching a plurality of scaffold mounting brackets from a plurality of tank mounting brackets, raising the continuously coupled plurality of scaffold sections, and reattaching the plurality of scaffold mounting brackets to a plurality of tank mounting brackets. Noting the plurality of scaffold sections is continuously coupled proximate a circumference of a shell tank, the continuously coupled scaffold sections and tank mounting brackets provide stiffness to the tank shell to enable it to resist external loads and can be quickly moved and restored as required during tank construction.
