Abstract: A pressure cylinder includes a working cylinder and an intensification cylinder that is divided by a separator block. A working piston is arranged in the working cylinder and connected to a working rod that extends to an end portion. An intensification piston and an intensification rod are arranged in the intensification cylinder. A pump is configured to provide a pressurized hydraulic fluid to the pressure cylinder. A fluid reservoir is configured to supply a hydraulic fluid to the pump. An overpressure circuit fluidly connects the advance working chamber and the retract passage, a pressure relief valve is arranged in overpressure circuit, the pressure relief valve is configured to open from a normally closed position to communicate fluid from the advance working chamber to the retract passage when the advance working chamber reaches an undesired threshold.

An intensification piston and an intensification rod are arranged in the intensification cylinder. A pump is configured to provide a pressurized hydraulic fluid to the pressure cylinder. A fluid reservoir is configured to supply a hydraulic fluid to the pump. A first valve is configured to selectively regulate hydraulic fluid flow between the pressure cylinder and the fluid reservoir and the pump. A second valve is configured to selectively regulate fluid flow between a first valve and the advance intensification chamber. A controller is in communication with the first valve and the second valve. The controller is configured to coordinate movement of the working piston and the intensification piston.
