ACTUATOR HAVING EXTERNAL LOAD SUPPORTING MEMBER

摘要

A hydraulic actuator is provided for supporting a load. The actuator include s 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 t he 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 wi th 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 raise d to support a tilt saddle member between the piston rod and the load after th e piston has been extended.
