Heavy-Duty Stabilization with Integrated Safety Control

DURA Hydraulic Jacks are engineered for demanding trailer and industrial applications where structural strength, lifting stability, and operational safety are critical. Each jack is equipped with an integrated counterbalance valve system designed to enhance both safety and performance.

Pressure Holding Protection

Every DURA hydraulic jack is fitted with Two counterbalance valves that:

• Lock the cylinder in position under load

• Prevent sudden drop in the event of hose failure or unexpected pressure loss

• Maintain load stability even during hydraulic interruption

This built-in safety feature protects equipment, cargo, and operators by eliminating uncontrolled movement.

Smooth & Controlled Operation

In addition to safety protection, the counterbalance valves also:

• Regulate oil flow for controlled descent

• Eliminate free-fall movement

• Ensure smooth extension and retraction

• Reduce shock loading on the trailer structure

The result is precise lifting control with enhanced system longevity.

Engineered for OEM Applications

• Heavy-duty steel construction

• Multiple stroke and mounting options

• Compatible with DURA power units

• Custom valve configurations available

Whether for dump trailers, equipment trailers, or specialty builds, DURA Hydraulic jacks deliver strength, stability, and controlled performance in every cycle.

Switch Valve Kits

To maximize flexibility in trailer applications, DURA also provides switch valve kits designed to integrate seamlessly with single-circuit power units. This solution allows one power unit to operate both hydraulic jacks and lifting cylinders (such as dump trailer hoists) within the same system
