ABSTRACT:
An intensifier is operable to supply force and includes a housing defining a cavity. A ram is slidably positioned within the cavity and partially extends from the housing. The intensifier also includes a force transfer rod and a plurality of power pistons. The ram is moveable between retracted and extended positions along a longitudinal axis. The force transfer rod is selectively moveable between a retracted position where the force transfer rod is not axially aligned with the ram and an advanced position where the force transfer rod is axially aligned with the ram. The plurality of power pistons are axially aligned with each other and the ram. The power pistons are selectively operable to provide an output force to the ram when the force transfer rod is in the advanced position.
