The company provides users with customized service such as product preliminary design, development and selection, design proposal finalization.
Leading products include Dump truck telescopic cylinder and Hydraulic system, Cylinder for mechanical equipment, Hydro-pneumatic suspension cylinder,Construction machinery cylinder, Electric cylinder,Hydraulic components serving the global commercial vehicle, smart mining, construction machinery and other industries. It is the core R & D and production base of hydraulic cylinders, hydraulic systems, oil and gas springs (suspension), and 100-ton electric servo cylinders.
Dump truck telescopic cylinder
The front-end cylinder is a multi-stage sleeve hydraulic cylinder, mainly used for dump truck, with double trunnions, eye+trunnion, double eyes and other connection types.
Energy mining equipment hydraulic cylinder
Energy mining equipment mainly includes various mechanical devices used for energy extraction such as coal, oil, and natural gas.
These devices play a vital role in energy production, not only improving extraction efficiency but also significantly reducing labor costs and safety risks.
The energy mining equipment hydraulic cylinders produced by our company are widely used in various energy mining equipment. They have the advantages of stable performance, reliable quality, long service life and good after-sales service.
Hydro-pneumatic suspension cylinder
The hydro-pneumatic suspension uses inert gas (nitrogen) as the elastic medium and oil as the force transmission medium, showing superior nonlinear elastic characteristics and good damping performance, which can meet the ride comfort requirements of engineering vehicles to the greatest extent.
Compared with other types of suspension, hydro-pneumatic suspension has significant advantages such as nonlinear stiffness, compact structure, and adjustable posture. It has a wide range of needs in military, off-road vehicles, construction vehicles and construction machinery.
Construction machinery hydraulic cylinder
Construction machinery hydraulic cylinders cover excavator cylinders and those for tunnel equipment. Excavator cylinders, with specs by tonnage, enable precise digging/loading, boasting high strength and wear resistance for harsh conditions. Tunnel ones, used in shield machines, roadheaders, shotcrete machines, etc., offer high pressure resistance and tight sealing for underground work. Our high-performance, stable cylinders, customizable per needs, ensure reliable power.
