    Double Acting Hydraulic Jack

    A Double-Acting Hydraulic Jack uses hydraulic pressure to move the piston in both directions – extension and retraction. Unlike single-acting jacks, it does not rely on load or springs for return.

    Working Principle

    • Oil pressure on piston (forward port) → piston extends (lifting)
    • Oil pressure on opposite side (return port) → piston retracts
    • Requires a double-acting hydraulic power pack with 4/3 directional control valve

    Key Features

    • Hydraulic force in both directions
    • Faster and more controlled operation
    • Works in horizontal or vertical position
    • Suitable for push–pull applications
    • Precise positioning

    Typical Specifications

    • Capacity: 5 ton to 500 ton
    • Stroke length: 50 mm to 1000 mm
    • Operating pressure: Up to 700 bar
    • Ports: Two oil ports (extend & retract)
    • Mounting: Clevis, flange, trunnion, base mount

    Applications

    • Heavy machinery lifting
    • Hydraulic presses
    • Die & mold handling
    • Construction equipment
    • Industrial automation
    • Bridge launching & maintenance

    Single Acting vs Double Acting

    Feature Single Acting Double Acting
    Extension Hydraulic Hydraulic
    Retraction Load / Spring Hydraulic
    Oil Ports 1 2
    Control Limited Full Control
    Speed & Precision Lower Higher

    Required Accessories

    • Double acting hydraulic power pack
    • Directional control valve (manual / solenoid)
    • High-pressure hoses
    • Pressure relief valve

    Support & Selection Assistance

    • Selection based on tonnage & stroke
    • Hydraulic power pack design
    • Quotation / datasheet format
    • Comparison with single acting jack
    • You can share your load capacity, stroke requirement, and usage type.
