This piston accumulator series is designed specifically for the hydro-pneumatic suspension system of large mining dump trucks. Serving as the core elastic energy-storage element and load-equalization device, it adopts a dual-piston design that separates the internal cavity into high-pressure and low-pressure gas chambers (or oil/gas chambers). Through gas compression and expansion, it absorbs road shocks in real time and equalizes the axle load, keeping the wheel loads of the middle and rear axles uniformly distributed and traction at an optimum — even under extreme conditions such as fully loaded uphill hauls on rough mine roads. This significantly improves ride quality and frame stress distribution. Built with an ultra-heavy-duty structure, reliable oil/gas separation sealing, and high-wear surface treatments, it operates stably in the high-pressure, high-frequency impact, slurry, and dust-laden environments typical of mining trucks.

The luffing cylinder is the primary power actuator for boom luffing on self-propelled aerial work platforms. It directly drives the main boom or articulated boom to pivot around its hinge point, determining the machine's maximum working height, horizontal outreach, and lifting capacity. As the main cylinder of the boom system, it withstands the highest thrust, pull, and bending loads. Built with a super-rigid structure, low-friction sealing system, and multiple integrated safety features, it delivers powerful, smooth lifting and zero-drift static holding under full-load frequent luffing, prolonged suspension, and harsh outdoor conditions.

This telescopic cylinder series is specifically engineered for the telescoping boom system of self-propelled aerial work platforms. As the core actuator for linear boom extension and retraction, it directly determines the machine's maximum working height and horizontal outreach. Featuring ultra-long stroke capability (up to 15 meters), a high-strength lightweight structure, and superior buckling resistance, it integrates precision sealing, multiple anti-corrosion treatments, and smart sensing interfaces. It delivers smooth, high-efficiency, and long-life performance under frequent telescoping cycles, full-rated-load luffing, and harsh outdoor conditions.

This outrigger cylinder series is purpose-designed for the chassis outrigger system of self-propelled aerial work platforms. As the primary actuator for stabilizing the machine during operation, it extends and raises the outriggers to create a rigid support foundation between the platform and the ground, preventing tipping or rocking with the boom fully extended and the platform at rated load. Built with a high-strength lightweight structure, ultra-low-friction sealing, and multiple anti-corrosion technologies, and integrated with safety valve packages including hydraulic locks, it delivers absolutely safe, stable, and reliable outrigger performance under extended static holding, frequent deployment, and harsh outdoor environments.

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.
