Types & Available Models

Mini & Compact Excavators

Engineered for urban utility work, landscaping, and tight-space operations. Feature zero-tail swing options, retractable undercarriages, and boom-offset functions for zero-clearance trenching along walls.

 

Medium Crawler Excavators

Designed for general civil construction, roadwork, and foundation excavation. Balanced ground pressure, reinforced track frames, and dual-pump load-sensing hydraulics ensure low fuel consumption per cubic meter shifted.

 

Heavy Mining Excavators

Built for quarrying and heavy earthmoving. Equipped with heavy-duty cast steel boom pivots, rock-type buckets with side cutters, dual air cleaners, and independent oil-cooling circuits for extended high-load duty cycles.

Quality Inspection & Testing

Ultrasonic & Radiographic Weld Inspection: Boom, arm, and track frame weld joints undergo 100% NDT (Non-Destructive Testing) to verify full-penetration welds and eliminate internal void formation under cyclic fatigue.

 

Hydraulic Pressure & Flow Benchmarking: Relief valves are calibrated to exact operating limits (up to 34.3 MPa). Main circuits run at maximum rated flow for 4 continuous hours to monitor fluid temperature stabilization and valve response.

 

100-Point Operation & Endurance Test: Completed units undergo a 2-hour field trial covering track travel tracking, slewing backlash, cylinder speed consistency, and bucket breakout force under loaded conditions.

 

Helium Leak Testing: Hydraulic pipelines and cooler blocks are pressurized to 1.5x working pressure to ensure zero fluid weeping at seals and O-rings.

 

Customization & Purchasing Options
 

Hydraulic Lines & Valves

Auxiliary single/dual-way lines for hydraulic breakers, augers, grapples, and tiltrotators.

Track Options

Rubber tracks for municipal asphalt preservation, wide steel shoes for soft terrain, or bolt-on rubber pads.

Cab & Climate Configurations

FOPS/ROPS certified enclosed cabs with high-capacity HVAC, air-suspension seating, or open canopy configurations.

Branding & Color Matching

Custom paint formulations, serial plate design, operator interface language localization, and customized user/parts manuals.

 

Shipping, Delivery & Export

 

1

Packaging & Loading

Mini/compact models (0.8t–3.5t) ship inside standard 20GP or 40HQ containers with steel tie-down cradles. Medium and heavy units ship via Flat Rack containers or Ro-Ro vessels with rust-inhibitor wax coating on exposed hydraulic cylinder rods.

2

Lead Times

Standard production cycles run 15–25 days from deposit confirmation. Custom OEM/hydraulic configurations deliver within 35–45 days.

3

Export Documentation

CE Certificates of Conformity, EPA Engine Certificates, Certificates of Origin (Form E, Form F, CO), Commercial Invoices, Packing Lists with HS Code declarations (HS 8429.52.10).

4

Warranty Support

Standard 12-month / 2,000-operating-hour warranty covering engine, main hydraulic pump, priority valve, and structural frame. Critical replacement parts ship via express air courier within 72 hours.

FAQ

 

Q: What engine emissions standards do your excavators comply with for European and North American markets?

A: We integrate EU Stage V and US EPA Tier 4 Final engines (such as Kubota, Yanmar, and Cummins) equipped with DPF and DEF/AdBlue systems. Certificates are provided with shipment for customs clearance in EU/US ports.

Q: Can you configure auxiliary hydraulic circuits for specialized attachments like tiltrotators or breakers?

A: Yes. We install dual-way proportional auxiliary lines controlled via joystick thumbwheels. Pressure and flow rates are adjustable via the cab monitor to match breaker, auger, shear, or tiltrotator specifications.

Q: How do you handle spare parts supply for international maintenance?

A: Primary hydraulic components (Kawasaki pumps, Rexroth valves) and engines (Cummins, Yanmar) share standard global part numbers, allowing local sourcing. For machine-specific structural or wear parts, we maintain a dedicated spare parts warehouse and dispatch air shipments within 48 to 72 hours.

Q: What is the Minimum Order Quantity (MOQ) for custom OEM orders?

A: For standard models, the MOQ is 1 unit. For custom color matching, private-label branding, or specific hydraulic line configurations, the MOQ is 2 to 5 units depending on machine tonnage.

Q: What non-destructive testing (NDT) do you perform on heavy structural components?

A: All boom and arm welds undergo ultrasonic testing (UT) and magnetic particle testing (MT) at key stress points (pivot pin housings and cylinder mounting brackets) to ensure structural integrity under heavy fatigue cycles.

Q: What are the loading conditions and ocean freight options for medium and heavy models?

A: Units under 6 tonnes fit inside standard 40HQ containers (up to 4 units per container depending on arm geometry). Machines above 13 tonnes are disassembled (boom/counterweight detached if necessary) and transported via Flat Rack or Ro-Ro shipping to prevent saltwater corrosion
