Stabilizer Hydraulic Cylinders

Stabilizer Hydraulic Cylinders

PWM Mechanical Locking Stabilizer Cylinders are engineered for demanding levelling and outrigger applications where precision, stability, and safety are critical. These cylinders are widely deployed across multiple industries, replacing outdated manual jacking and blocking methods with advanced hydraulic stabilization technology.

Common Applications Include:

  • Aggregate equipment – crushers, screen decks, conveyors, grizzlies, and other heavy processing machinery.
  • Mobile trailers for fixed deployment – radar units, communication towers, observation trailers, and other mobile infrastructure.
  • Oil and gas equipment – service rigs, coiled tubing units, drilling rigs, catwalks, and tubular handling systems.
  • Mobile cranes – used in both commercial and industrial lifting operations.

  • Advantages of PWM Mechanical Locking Stabilizer Cylinders
    • Operator Efficiency – Faster and easier setup compared to manual jacking systems.
    • Precision Positioning – Infinite adjustment capability ensures exact leveling in the field.
    • Positive Locking – Mechanical locking prevents unintentional cylinder movement, ensuring operator and equipment safety.
    • Enhanced Reliability – Built with robust materials for long service life in demanding environments.
  • Standard Cylinder Lineup
    • PWM offers a pre-engineered series of Mechanical Locking Stabilizer Cylinders in both Standard and Ball End designs, enabling OEMs to benefit from reduced lead times and consistent quality.
    • Bore sizes: 4″ to 6″
    • Stroke lengths: 12″ to 30″
    • Working pressure: up to 3,000 PSI
    • Locking mechanism: external adjustable solid or split ring design to secure position and eliminate manual blocking.
  • Standard Features
    • High-tensile, cold-drawn barrel tube, precision honed for extended seal life.
    • Ductile iron piston and gland (ASTM A536, 65-45-12) for superior strength.
    • 4 TPI Acme locking threads for secure mechanical engagement.
    • NPT ports (other porting options available upon request).
    • Grade C, high-tensile piston locknut for secure retention.
    • Durable urethane gloss paint finish (custom colors available).
    • Steel port plugs installed for shipping protection.
  • Custom Engineering Options
    • PWM’s engineering team collaborates closely with OEMs to design fully customized stabilizer cylinders, integrating application-specific requirements for maximum functionality and performance.
      • Available Custom Options:
        • Larger bore diameters for higher load capacities.
        • Extended stroke lengths beyond standard range.
        • Specialized mounting configurations.
        • Alternative porting (ORB, side ports, or custom layouts).
        • Integrated counterbalance valves for controlled lowering.
        • Internal pilot-operated check valves for load holding.
        • Optional split retaining nuts for simplified serviceability.
        • Jacking pad attachments for ground stability.
        • Custom paint finishes in durable urethane gloss coatings.
  • Quality Assurance
    • Every PWM Mechanical Locking Stabilizer Cylinder, whether standard or custom, undergoes 100% hydraulic pressure testing to verify performance, safety, and compliance with customer specifications
