Our manufacturing facility is organized into six specialized production units to cover the full range of excavator hydraulic components:
1. Hydraulic Pump Assembly Workshop
Dedicated to remanufacturing and assembling main hydraulic pumps for crawler excavators, covering K3V, K5V, HPV, A8VO, PSVL and PSVD series. Equipped with dynamic test benches capable of validating flow rates up to 500 L/min and pressures up to 45 MPa.
2. Precision Machining Center
20+ CNC lathes and 4-axis machining centers produce pump shafts, cylinder blocks, valve plates, pistons, swash plates, and bearing housings. Tolerances are maintained within ±0.005mm for all critical rotating components.
3. Final Drive & Swing Motor Workshop
Specializes in travel
motor and swing motor assembly and testing for major excavator brands including Hitachi, Komatsu, Caterpillar, Kobelco, and Hyundai. Each unit undergoes load testing simulating real-world operating conditions before shipment.
4. Control Valve & Hydraulic Safety Valve Unit
Produces main control valves, relief valves, safety valves, unloading valves, and pump control valves for excavators from 5 to 50 tons. Every valve is individually calibrated on digital hydraulic test benches with pressure certification documentation.
5. Solenoid Valve & Electrical Components Line
Manufactures solenoid valves, proportional valves, pressure switches, and electronic sensors for excavator hydraulic systems. Includes automated coil winding, resistance testing, and response time verification stations.
6. Small Components & Accessories Workshop
Produces joysticks, center swivel joints, cooling fan motors, gear pumps, oil pumps, and pump coupling components. Lean manufacturing cells allow flexible batch sizes from 20 to 2,000 pieces.
