Method for installing an elevator system

A method of installing an elevator system on a wall of an elevated structure having a plurality of rail mast sections and an elevator car, said method comprising the steps of:

• (a) placing a sheaved mechanism on the structure at a point above the desired elevated position of the finally installed rail mast sections,
• (b) interconnecting one end of a wire rope through said sheaved mechanism to a power hoist,
• (c) connecting the free end of the wire rope to the upper end of a first rail mast section,
• (d) raising the first rail mast section off the ground by a distance substantially equal to the length of said rail mast section through selective activation of the power hoist,
• (e) affixing the upper end of the next rail mast section to the bottom end of the first rail mast section,
• (f) repeating steps (d) and (e) for each successive rail mast section until the first rail mast section is at the desired elevated position on the structure,
• (g) raising the affixed rail mast sections the height of the elevator car,
• (h) placing the elevator car under the raised rail mast sections,
• (i) lowering the rail sections into the elevator car so that the rail sections operatively interconnect with the elevator car,
• (j) raising the interconnected rail mast sections and elevator car,
• (k) mounting a predetermined number of rail mast sections to the structure and to each other,
• (l) interconnecting the lowermost rail mast section of said raised sections to the uppermost section of said mounted predetermined number of sections,
• (m) mounting each interconnected rail section to the structure by selectively raising the elevator, and
• (n) removing the wire rope and sheaved mechanism from the structure.
