Definitions

  • This disclosure relates to access systems, and particularly to systems designed to access undersurfaces and side surfaces of large stationary structures. More particularly, this disclosure relates to a monorail system which is used in combination with a scaffold structure and from which a further scaffold structure may be suspended and moved, relative to a structure being accessed, vertically and parallel with the monorail track.
  • Suspended scaffolding is known and may be used in certain instances to access such side surfaces and undersurfaces. Suspended scaffolding comes with its own difficulties. For example, it may not be practical or possible to suspend scaffolding in a location from which workers are able to access the necessary surface. The length of a surface may also be a limiting factor. If the structure being accessed spans a great length, the amount of suspended scaffolding may require multiple rounds of assembly/disassembly to complete the entire job. Further, and particularly with arched structures, the suspended scaffolding may need to have multiple levels resulting in further complexity and time in assembly/disassembly.
