Abstract A lifting apparatus, comprising: a piston assembly movably disposed in a cylinder for lifting and supporting machinery, the piston assembly comprising an outwardly extending threaded member adapted for movement with the piston assembly; a locking nut adapted for being selectively engaged with the threaded member for limiting axial movement of the piston assembly such that in at least one operable configuration, the locking nut is positioned in a spaced relationship relative to an upper portion of the cylinder to limit downward movement of the threaded member due to failure of the piston assembly. 6070 -45 100 60 r 4 Figure 1
