Inverted pedestal crane

An inverted pedestal crane for use in load handling operations, comprising:

• a circular base;
• a means secured to a top surface of said base for supporting the base from an underside of a horizontal support structure;
• a pedestal extending downwardly from said base, said base and said pedestal rotating about a vertical axis, said base having a diameter substantially greater than a peripheral outer surface of said pedestal, said pedestal having an unsupported lower portion;
• a boom pivotally connected to said pedestal;
• a rotating assembly mounted above said pedestal for rotating said pedestal about a vertical axis, said rotating assembly comprising a pair of parallel plates retained in a spaced-apart relationship to each other, a plurality of centering roller located adjacent a center of each of said plates for centering position of said pedestal in relation to said base and a plurality of stabilizing rollers mounted a distance from said centering rollers adjacent to outer edge of said plates;
• a means coupled to said pedestal and said boom for pivotally moving said boom in relation to said pedestal;
• and
• a truss assembly secured to said pedestal and to an underside of said base, said truss assembly resisting overturning moments acting in said crane when said boom engages a load.
