Abstract: A method for installing an elevator system on a wall of an elevated structure having a plurality of rail mast sections and an elevator car. The method includes the steps of raising a first rail mast section upwardly off of the ground by a distance substantially equal to the length of the rail mast section, affixing the upper end of the next rail mast section to the bottom end of the first rail mast section, then repeating the above two steps until a desired number of rail mast sections are affixed. The assemblage of rail mast sections are then raised substantially equal to the height of the elevator car and the elevator car is placed under the raised assemblage of sections, the assemblage of raised mast sections are then lowered into the elevator car. Finally the assemblage of rail mast sections interconnected with the elevator are raised and the final three rail mast sections are attached to the wall and to the raised assemblage.
