Abstract: A system is provided for two speed movement of a hydraulically driven element. The system includes a housing for a primary piston having a longitudinal bore open at one end. A secondary piston is received within the open bore end to define a secondary expandable reservoir within the primary piston. The primary piston includes a secondary working face disposed within the secondary expandable reservoir and a primary working face disposed in a primary expandable reservoir. High pressure hydraulic fluid is introduced into the secondary expandable reservoir for high speed movement. When the primary piston reaches a predetermined location, high pressure hydraulic fluid is introduced into both reservoirs for low speed movement.
