This dozer cylinder is purpose-built for the lift and lower function of the dozer blade at the rear of mini excavators, enabling quick grading, backfilling, and machine stabilization. Engineered with high-strength structure, heavy-duty sealing, and multiple surface protections, it operates reliably in high-shock, high-debris environments.

This swing cylinder (offset cylinder) is engineered for mini excavator boom offset function, enabling the boom to swing left and right to significantly expand working coverage. It is ideal for trenching in tight spaces, slope grading, and utility work. Built with high-strength materials, advanced sealing systems, and multiple anti-corrosion treatments, it delivers outstanding durability under high pressure and high cycling loads.

This front suspension cylinder series is the core load-bearing and damping element of the hydro-pneumatic suspension system on large mining dump trucks. Mounted between the front axle and the chassis frame, it simultaneously supports the front laden weight, absorbs road shocks, attenuates body vibration, and maintains front wheel ground contact through the elastic-damping coupling of high-pressure oil and nitrogen gas. Compared to rear suspension, the front suspension must additionally accommodate side loads and angular articulation from steering; therefore, the cylinder features a reinforced anti-side-load guiding system and maintenance-free spherical pivot connections. Together with custom-tuned non-linear stiffness and damping characteristics based on vehicle parameters, it ensures superior ride comfort, steering precision, and frame durability under combined operating conditions such as loaded downhill hauls, rough curved roads, and braking.

This rear suspension cylinder series is the core load-bearing and damping element of the hydro-pneumatic suspension system on large mining dump trucks. Mounted between the rear axle and the chassis frame, it supports the fully loaded vehicle weight, absorbs road shocks, attenuates body vibration, and equalizes axle load distribution through the combined action of hydraulic oil and high-pressure nitrogen. Featuring an ultra-high pressure design (rated 38 MPa) and large-diameter piston construction, and operating in conjunction with external or built-in accumulators, it delivers non-linear stiffness and damping characteristics. This ensures excellent ride comfort and uniform frame stress distribution under extreme conditions such as fully loaded uphill hauls, rough mine roads, and heavy dumping, significantly extending chassis and tire life. Enhanced for the rock impacts, mud, dust, and continuous heavy-duty operation typical of open-pit mines, it offers exceptional fatigue durability and long-term reliability.

This lifting cylinder series is the core actuator of the dump body hoist system on large mining dump trucks. Mounted between the chassis frame and the dump body underbelly, it hydraulically raises and lowers the body to rapidly discharge ore, overburden, and other bulk materials. Employing a multi-stage telescopic design (typically 2-stage or 3-stage), it achieves an ultra-long stroke and tens of thousands of kN of thrust within a compact retracted length, ensuring smooth, safe dumping even at full load on several-hundred-tonne class trucks. Built with an extreme heavy-duty structure, purpose-designed multi-stage sealing, and built-in cushioning, it operates reliably under continuous heavy-duty cycles, frequent hoisting, and intense vibration in mining environments.

This steering cylinder series is purpose-built for the chassis steering system of large mining dump trucks. Serving as the core actuator linking the steering linkage and knuckles, it hydraulically assists wheel deflection, providing precise and smooth steering response under full load, on rough mine roads, and during frequent maneuvering. The cylinder ensures handling stability and even tire wear. Enhanced for open-pit mine conditions — rock impacts, mud, dust, and continuous long-distance operation — it delivers exceptional fatigue durability and maintenance-free capability.

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.
