• Precise Fuel Injection: High-pressure common rail system with electronic control ensures optimal combustion.
• Gear Mapping Efficiency: The HW19710’s close-ratio gears allow sustained operation within the engine’s peak torque band (1,400–1,600 rpm), reducing lugging and over-revving.
• Average Fuel Consumption:
• Loaded (67.5-ton payload): 38–42 L/100 km (on mixed terrain, 60% highway, 40% rural)
• Unloaded: 28–32 L/100 km
• Fuel Tank Capacity: 300 L (dual-side) – supports up to 700 km range under typical load.

Note: Fuel efficiency improves by up to 8% with trained drivers using RPM management protocols.

---

Load Capacity & Operational Performance

The trailer is engineered for maximum load security and distribution when transporting heavy excavators (e.g., Caterpillar 336, Komatsu PC360, Hitachi ZX350):

• Max Excavator Weight Supported: 35,000 kg (standard), up to 40,000 kg with reinforced deck option.
• Center of Gravity Management: Low deck height (950 mm from ground) enhances roll stability.
• Load Distribution: Adjustable axle spacing (1.3 m to 1.8 m) ensures legal axle load compliance across jurisdictions.
• Payload Margin: 67.5-ton net capacity allows transport of excavator + attachments (e.g., breaker, auger, plate compactor) without overload risk.

---

4. Method-Specific Analysis

4.1 RO-RO (Roll-on/Roll-off)

• Advantages:
• Rapid loading/unloading; reduced port demurrage.
• Minimal handling damage for functional units.
• Direct drive-on capability reduces rigging complexity.
• Limitations:
• Requires trailer to be operational or towable.
• Limited protection from salt spray and UV exposure.
• Higher exposure to deck moisture and condensation.

4.2 Bulk Cargo

• Advantages:
• Lower base freight cost for non-containerized loads.
• Suitable for oversized units exceeding container limits.
• Limitations:
• High risk of mechanical damage due to shifting.
• No standardized securing; moisture ingress in holds.
• Extended port handling increases downtime.
• Not recommended for high-value or corrosion-sensitive equipment.

4.3 Flat Rack Containers

• Advantages:
• Full structural containment with lashing points (ISO standard).
• Compatibility with container vessels and intermodal transport.
• Can accommodate non-operational or disassembled units.
• Enables full application of corrosion protection systems.
• Limitations:
• Higher freight cost due to container utilization.
• Requires crane access at both origin and destination.

5. Corrosion Protection: Wax Spraying System

5.1 Requirement

Excavator trailers are highly susceptible to marine atmospheric corrosion during ocean transit due to prolonged exposure to salt-laden air, humidity, and temperature fluctuations.

5.2 Recommended Solution: Industrial Wax Spraying

A solvent-free, hydrophobic wax emulsion is applied to all exposed metallic surfaces pre-shipment.

Feature	Specification
Product Type	Long-term rust preventive wax (VCI-enhanced optional)
Application Method	High-pressure spray (15–20 bar), full coverage
Coverage Areas	Frame rails, weld joints, undercarriage, hydraulic mounts, fasteners
Thickness	20–30 µm dry film
Protection Duration	Up to 12 months (ISO 9223 corrosivity class C5-M)
Removal	Biodegradable solvent or hot alkaline wash (post-delivery)

5.3 Process Workflow

1. Pre-treatment: Degrease and dry all metal surfaces.
2. Mask electrical enclosures and tires.
3. Apply wax spray in controlled environment (15–25°C, <70% RH).
4. Cure for 4 hours before containerization.
5. Document application with batch traceability.

Compliance: Meets ASTM D1745 and ISO 12944-6 standards for temporary corrosion protection.

---

6. Recommendations

Priority	Recommendation
1	Use Flat Rack containers for non-operational or high-value excavator trailers to ensure structural integrity and corrosion control.
2	Apply industrial wax spraying as mandatory pre-shipment treatment for all export units, regardless of shipping method.
3	RO-RO is viable only for fully operational units with immediate post-arrival deployment and access to Ro-Ro terminals.
4	Avoid Bulk Cargo due to unacceptably high risk of mechanical and environmental damage.

---

7. Conclusion

For reliable, damage-free delivery of excavator trailers from China, Flat Rack containerization combined with industrial wax-based corrosion protection represents the optimal logistics solution. While RO-RO offers speed, its environmental exposure risks necessitate rigorous surface protection. Bulk cargo is not advised due to poor controllability and high incident rates. SEA LION International recommends integrating wax spraying into OEM outbound protocols to ensure asset longevity and reduce warranty claims.
