ABSTRACT:
A method and apparatus particularly suited to the manufacture and assembly of cage-like, substantially cylindrical structures made of long, slender tubular components which, by themselves, are not self-supporting, employs an exo-skeleton structure to assemble cage-like, tubular structures in pie-shaped, longitudinal segments while in a horizontal or vertical position utilizing longitudinal or circumferential attachments. The apparatus comprises at least two segments which permit construction of subassemblies of the cage-like, tubular structure and their transportation, if necessary, to a remote site where they may be finally assembled.
