ABSTRACT:
A drive frame assembly includes opposite transverse drive frame members (64), each of which includes a metal plate (66) with a central portion having a plurality of longitudinal corrugations (68). The plate (66) is stiffened by transverse beams (78, 80). A plurality of piston-cylinder drive units each have opposite ball ends (24, 26) which are secured to end portions of the corrugations by means of ball blocks (50, 52). Opposite side portions of the plate (66) are secured to laterally spaced portions of a main frame of a structure. The connections are made by a fastener/shim arrangement to accommodate variations in vertical spacing of the drive units relative to the portions of the main frame.
