ABSTRACT:
An extensible stabilizing tower similar to those positioned about hydraulic cylinders having multiple extensible stages is modified to effectively connect cylinders vertically in series. An upper stage of the stabilizing tower supports an upper cylinder or parallel cylinders, and base parallel cylinders connected to the base of the stabilizing tower are operative to lift the upper stage supporting the upper cylinder. A load connected to the header of the upper cylinder is lifted a distance equal to the sum of the extension of the base cylinders and the subsequent extension of the upper cylinder.
