Abstract
An illustrative example embodiment of an assembly includes a first platform and at least one first brace associated with the first platform. The first brace is configured to engage a surface in or near a hoistway for supporting the first platform in a vertical location near the surface. A portion of the first brace is moveable relative to the first platform between an extended position for engaging the surface and a retracted position for allowing the first platform to move relative to the surface. A second platform is vertically spaced from the first platform. An adjustment mechanism associated with the first platform and the second platform facilitates adjusting a vertical spacing between the first platform and the second platform.
