  • Patent number: 9573263
    Abstract: A hand-held hydraulic assembly includes a work tool having a hydraulic cylinder or main body, a ram piston disposed in the hydraulic main body and a spring or other biasing member mounted on the ram piston. An interchangeable work head is selectively engaged to the ram piston of the work tool. The ram piston is axially displaceable in the main body for actuating the work head. A quick release coupling mounted to the work tool releasably connects the interchangeable work head to the work tool.
