ABSTRACT:
A hydraulic actuator is provided for supporting a load. The actuator includes a cylinder, a lower end closed by a base, and an annular side wall connected between the base and the upper wall. A piston is disposed partially within the cylinder, and includes a rod extending through the upper end of the cylinder, and a piston head that defines a hydraulic chamber with the base. A cylinder chamber is disposed between the base and the piston head and communicates with a fluid source and a fluid return to correspondingly extend and retract the piston. A support member is connected to the cylinder wall, and can be raised to support a tilt saddle member between the piston rod and the load after the piston has been extended.
