<p>A work platform system is disclosed for positioning within a structure, such as a blast furnace. A base portion is placed within the structure and a tower mast secured thereto extends vertically therefrom. An annular platform and an elevator are secured to the tower mast for vertical movement therealong, and the platform has an opening defined therethrough to accommodate passage of the elevator. The platform may be extended and radially expanded to provide access to any point within the structure, while substantially accommodating width variations within the structure. Unlike conventional systems, repositioning of the system around the structure to access the vertical walls thereof is substantially avoided, and the system is adapted to be transportable in a disassembled state.</p> |
