Abstract
Collapsible scaffolding comprises a number of platforms which can be suspended in spaced vertical array for chains secured to the corners of the platform, and arranged at the top for the support of the scaffolding by a crane or a horizontally movable trolley. Additional cables at each end of the platforms are each secured at the lower end to the lowest platform and pass through guides secured to the intermediate and top platforms to a winch enabling the platform to be quickly lifted and stacked but allowing them to be quickly lowered and erected. The guides provide lateral location of the stacked platforms.
