ABSTRACT:
A rotary tower crane has a tower constructed from uniformly sized sections which can be arranged to provide a tower of small or large cross section, as required. The tower sections can be aligned in a single, vertical column to provide a tower having a narrow cross section, or a plurality of sections can be joined horizontally to form sections of enlarged cross section, which are then vertically aligned to provide a tower having an enlarged cross section.
