Fuel Efficiency Analysis

The Weichai WD615.62G3 engine is calibrated for industrial load cycles and features high-pressure common rail (HPCR) fuel injection, enabling precise combustion control. Under standard operating conditions (continuous excavation at 85% load), the excavator achieves:

• Average Fuel Consumption: 28–32 L/h (7.4–8.5 US gal/h)
• Specific Fuel Consumption: 215 g/kWh (at rated power)

This equates to a 12–15% improvement in fuel efficiency over previous-generation models using non-common rail systems. The HW19710 transmission contributes to this efficiency by minimizing driveline losses through optimized gear ratios and low-friction synchromesh engagement.

Regenerative idling and automatic engine shutdown (programmable) further reduce idle fuel burn, particularly during short pauses in operation.

Film Thickness	50–80 µm (dry film)
Salt Spray Resistance	ASTM B117: 1,000+ hours
Temperature Range	-30°C to +80°C
Removability	Biodegradable solvent or hot alkaline wash
Certification	ISO 12944-6:2018 (C5-M Marine Environment)

Operational Note: Wax application must occur post-final assembly (or post-packaging for disassembled units) and prior to containerization or vessel loading. Re-inspection is recommended at discharge port before reassembly.

---

Recommendation Matrix

Project Requirement	Recommended Method	Rationale
BWE < 250t, mobile, coastal destination	RO-RO	Fast, low-handling risk, cost-effective
BWE > 500t, inland destination	Bulk Cargo	Accommodates oversized loads; direct offload near river/rail access
Modular BWE, precision handling needed	Flat Rack (40’ HC FR)	Enables phased transport, inspection, and staged reassembly
High corrosion risk route (e.g., tropical waters)	All + Wax Spray	Mandatory wax protection regardless of method

---

Conclusion

Exporting bucket wheel excavators from China demands a tailored logistics strategy based on equipment configuration, destination infrastructure, and environmental exposure. While RO-RO offers speed and simplicity for smaller units, Bulk Cargo and Flat Rack solutions dominate for large-scale deployments. Universal application of industrial wax spraying is non-negotiable to ensure asset integrity across all shipping modes. SEA LION International recommends pre-shipment engineering audits to determine optimal disassembly, packaging, and transport routing.
