The supporting structure (1), set beneath a raised floor (P), comprises at least two vertical and parallel panels (2), with a horizontal panel (4) between them in an H-section configuration, forming a cavity (R) with its transverse dimension corresponding exactly to that of the hydraulic pivot housing (7). The lower edges of the vertical panels are fitted with adjustable screw jacks (5) to raise them to the level of the underside of the raised floor. Two additional vertical panels (3) are incorporated inside the man ones to support the horizontal panel.
