This bucket cylinder series is designed for 20 to 80 metric ton medium and large hydraulic excavators. As the final actuator controlling bucket curl for cutting, loading, and dumping, it directly determines breakout force and cycle productivity. Built to a 35 MPa ultra-high pressure specification, it features high burst force, strong side-load tolerance, and excellent impact resistance. Integrated adjustable cushioning, large-flow dual ports, and a smart sensing interface ensure consistent, efficient output in extreme operations including overburden removal, rock excavation, and heavy-duty truck loading.

This boom cylinder series is engineered for 20 to 80 metric ton medium and large hydraulic excavators. As the core actuator for raising and lowering the boom, it directly determines maximum digging height, reach at dump, and heavy lifting capacity. Featuring a 35 MPa ultra-high pressure design, oversized bore, thick-walled barrel, integrated adjustable cushioning, large-flow dual ports, and smart sensor readiness, it delivers smooth, powerful motion and exceptional durability in the toughest applications such as overburden handling, heavy rock face digging, and deep trench work.

This stick cylinder series is purpose-built for 20–80 ton medium and large crawler excavators. Serving as the core hydraulic actuator for stick extension and retraction, it handles digging, loading, and dumping operations. With a 35 MPa ultra-high pressure design, thick-walled barrel, large-diameter piston rod, high-flow hydraulic control system, adjustable cushion valve, and intelligent sensor interface, it delivers robust force and low downtime in demanding applications such as overburden removal, heavy rock handling, and deep trench excavation.

This track tension cylinder series is engineered for medium and large hydraulic excavators. It continuously adjusts track tension to prevent derailment and slippage, ensuring stable and safe travel. With an ultra-high pressure design (rated 35 MPa), oversized bore, thick-walled barrel, and excellent side-load capacity, combined with long-life sealing and multiple anti-corrosion treatments, it delivers exceptional reliability and durability in extreme environments such as quarries, mines, and swampy terrain.

The bucket cylinder is the final hydraulic actuator for bucket digging, curling, and dumping on mini excavators. It directly determines breakout force, dumping height, and cycle speed. Engineered with high-strength impact-resistant materials, a precision sealing system, and comprehensive surface protection, this cylinder series withstands alternating loads, high pressure, and severe environments such as mud, water immersion, and debris, delivering reliable digging power.

The boom cylinder is the core actuator for mini excavators, directly responsible for lifting and lowering the boom. It determines the machine's digging depth, lifting capacity, and cycle efficiency. Built with high-strength materials, advanced sealing and cushioning technologies, and multiple surface protection options, it delivers stable, safe, and long-lasting performance under heavy digging loads, frequent cycling, and harsh environments.

This stick cylinder is specifically engineered for the extension and retraction of the stick (arm) on mini excavators. It directly influences the machine’s digging reach, breakout force, and loading height. With a compact heavy-duty structure, low-friction sealing system, and multiple anti-corrosion treatments, it delivers consistent, precise power in frequent reversing, high-impact, and aggressive environments.

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.
