This suspension cylinder series is designed for independent chassis suspension systems of truck cranes and all-terrain cranes. Serving as the core actuator and damping component of hydro-pneumatic or active suspension systems, it combines elastic support, shock absorption, and ride height adjustment in one unit. Operating in conjunction with accumulators, the cylinder absorbs road shocks and vibrations while enabling dynamic chassis height control, ensuring superior ride comfort, stability, and tire ground contact during highway travel, off-road driving, and lifting operations. Built with a high-rigidity lightweight structure, ultra-low-friction long-life sealing, and multiple anti-corrosion solutions, it provides long-lasting reliability under all-weather, heavy-duty, and high-impact conditions.

This outrigger extension cylinder series serves as the horizontal actuator for truck crane chassis outrigger systems. It extends and retracts the outrigger beams horizontally from the vehicle sides, expanding the overall stabilizer span to provide a solid base for the vertical jack cylinders. The cylinder features an ultra-long stroke (up to 2500mm or more), a lightweight high-strength design, and can be built in two- or three-stage telescopic configurations to achieve large extension ratios within compact retracted lengths. Integrated low-friction sealing, a corrosion-resistant guide system, and multi-function safety valve packages ensure long-term smooth, stick-free horizontal deployment in severe conditions such as frequent cycling, mud, and winter road salts.

This counterweight cylinder series is the core actuator for the self-installation counterweight system of truck cranes. It lifts, lowers, and shifts counterweights, enabling rapid assembly and disassembly without auxiliary lifting equipment — greatly improving job-site relocation efficiency. Built with a high-strength lightweight structure, ultra-low-friction sealing, multiple anti-corrosion treatments, and integrated safety valve packages such as hydraulic locks, the cylinder can be supplied in multi-stage configurations with dual independent control and specialized guide rail assemblies for all-terrain chassis. It ensures safe holding, smooth motion, and long service life under heavy counterweight masses (several to tens of tons) and frequent relocation operations.

This steering cylinder series is designed for the chassis steering system of truck cranes. It drives the steering linkage or knuckles to precisely angle the wheels, delivering excellent maneuverability and safety margins during on-highway travel, tight job-site steering, and all-terrain off-road conditions. Featuring a lightweight, high-strength structure, ultra-low-friction sealing, and multiple anti-corrosion treatments, the cylinders can be supplied in multi-stage configurations with dual independent control circuits and specialized guide rail assemblies for all-terrain cranes, meeting modern truck crane demands for precise steering, durability, and low maintenance.

The luffing cylinder is the primary power actuator for the boom luffing system of truck cranes and all-terrain cranes. It directly drives the main or auxiliary boom to pivot around its hinge point, determining the machine's maximum lifting height, working radius, and overall lifting capacity — making it the "main cylinder" of the crane. Featuring an oversized design (bore up to 570 mm, stroke up to 5000 mm), ultra-high pressure construction (rated 36 MPa), and a high-strength thick-walled barrel, it withstands the greatest thrust, pull, and bending loads on the entire crane. Integrated with a low-friction sealing system, adjustable cushioning safety valve packages, and smart sensing interfaces, it delivers powerful, smooth, zero-drift lifting motion and exceptional fatigue life under full-load frequent luffing, prolonged loaded suspension, and the harshest operating environments.

This telescopic cylinder series is the core actuator for the telescopic boom system of truck cranes and all-terrain cranes. It directly drives the sequential extension and retraction of the main or auxiliary boom sections, determining the crane’s maximum lifting height and working radius. Designed for ultra-high pressure (rated 35 MPa, max 42 MPa) and available in single-stage to multi-stage (double, triple, or even quadruple) configurations with ultra-long strokes (up to 23 meters), the cylinder integrates a high-strength lightweight structure, precision sealing and guiding systems, multiple safety valve packages, and smart sensing interfaces. It delivers smooth, efficient, zero-drift boom motion and exceptional service life under heavy lifting, frequent telescoping, and harsh outdoor environments.

The outrigger cylinder is the vertical load-bearing core of the truck crane chassis outrigger system. During lifting operations, it extends under hydraulic power to elevate and stabilize the entire machine, reliably transferring vehicle weight and hoisting loads to the ground. It forms a rigid support that prevents tipping and sinking under varied ground conditions and within the full rated lifting range. Designed for ultra-high pressure (rated 35 MPa, max 42 MPa) with large-diameter piston rods and thick-walled barrels, it can be configured in multi-stage telescopic versions for extended stroke. Integrated safety valve packages and corrosion-proof guide systems ensure safe lockout, smooth lifting, and long service life under heavy reaction forces of several to tens of tons, and in harsh environments such as mud, winter road salts, and coastal salt spray.
