Fuel Efficiency Analysis

The WD615/Weichai WP10G engine platform integrates high-pressure common rail (HPCR) fuel injection and electronically optimized combustion control, resulting in improved thermal efficiency and lower specific fuel consumption. Under mixed operating cycles (digging, swinging, and idling), the average fuel consumption is approximately 28–33 L/h.

In eco-mode operation with optimized hydraulic pump matching, fuel efficiency improves by 12–15%, achieving ~24 L/h during light-load trenching or grading. The HW19710 transmission contributes to fuel economy through load-sensing shift logic and reduced parasitic losses in high-gear cruising during transport or repositioning.

Annual fuel savings in a 1,800-hour operational cycle (typical for heavy infrastructure projects) are estimated at 8,640–10,800 L compared to legacy Tier II platforms, translating to significant operational cost reductions.

---

Load Capacity & Structural Performance

The 330-class excavator is engineered for high-durability applications in quarrying, mass excavation, and foundation work. Key load-bearing features include:

• Reinforced Undercarriage: Heavy-duty track frames with hardened steel rollers and idlers rated for 12,000 hours MTBF.
• Axle Load Distribution: Optimized front-to-rear ratio (41% front / 59% rear) ensures stability during boom extension and swing under full bucket load.
• Lifting Capacity: Up to 12.8 tons at 6 m radius (boom 45°, arm 90°, ground level), per ISO 10968 standards.
• Bucket Breakout Force: 220 kN (standard configuration), expandable to 270 kN with high-flow auxiliary hydraulics.

The 12.00R20 tires (when equipped on transport trailers or wheeled variants) support safe road travel at speeds up to 80 km/h, with dynamic load amplification accounted for in axle rating margins. Tires are specified with cut- and wear-resistant tread compounds suitable for off-road haul roads and job site transitions.

---

Conclusion

The 330-class excavator with Weichai WD615/WP10G powertrain and HW19710 transmission delivers robust performance, competitive fuel efficiency, and high load tolerance essential for large-scale construction and mining operations. The integration of industrial-grade components ensures durability, reduced downtime, and lower cost-per-hour compared to non-OEM-aligned alternatives. Recommended for fleet deployment in high-utilization environments requiring reliability and serviceability.

4. Corrosion Protection: Wax Spraying Treatment

Seawater exposure during ocean transit poses a significant risk to excavator undercarriages, hydraulic cylinders, and structural steel components. SEA LION International mandates industrial-grade wax-based anti-corrosion treatment for all exported 330-class units, regardless of shipping method.

4.1 Wax Spraying Protocol (ISO 12944-2 Compliant)

Parameter	Specification
Coating Type	Solvent-based, hydrophobic wax emulsion
Application Method	High-pressure spray (20–30 bar)
Coverage Areas	Undercarriage, track frames, boom/pins, hydraulic rods, cavity zones
Film Thickness	50–75 µm (dry)
Drying Time	2–4 hours (ambient 25°C)
Salt Spray Resistance	>1,000 hrs (ASTM B117)
Removability	Biodegradable solvent or steam stripping

4.2 Method-Specific Protection Efficacy

Shipping Method	Exposure Risk	Wax Protection Efficacy	Additional Measures
RO-RO	High	High (full coverage)	Wheel well sealing, desiccant in cab
Bulk Cargo	Very High	Medium–High	Tarpaulin wrapping, VCI bags in cabin
Flat Rack	High	High	Shrink-wrapping, corner protectors

Note: Wax treatment is non-negotiable and performed at certified pre-shipment centers in Chinese export ports.

---

5. Recommendations by Use Case

Client Profile	Preferred Method	Rationale
Large Infrastructure Contractor (50+ units/year)	RO-RO	Lower handling risk, faster turnaround, scalable logistics
Mid-Sized Contractor (5–20 units/year)	Flat Rack	Better asset control, compatibility with containerized multimodal transit
Budget-Constrained Project	Bulk Cargo	Lowest cost; acceptable with enhanced wax + tarpaulin protection

---

6. Compliance & Documentation

All shipments comply with:
– IMDG Code (for fuel/hydraulic fluids)
– China Customs Export Declaration (HS Code: 8429.52.10)
– CIQS Pre-shipment Inspection (if required)
– Bill of Lading, Packing List, Certificate of Origin, and Anti-Corrosion Treatment Certificate issued per shipment

---

7. Conclusion

For optimal balance of cost, safety, and equipment integrity in exporting Cat 330 excavators from China, RO-RO is recommended for high-volume operations, while Flat Rack offers superior protection for critical or isolated units. Bulk Cargo remains a cost-driven alternative but demands rigorous anti-corrosion and securing protocols. Wax spraying is essential across all methods to ensure equipment readiness upon arrival.
