4. Corrosion Protection: Wax Spraying Treatment

Seawater exposure during maritime transport poses a significant risk to excavator integrity, particularly in hydraulic lines, pivot points, undercarriage rollers, and electrical housings.

Recommended Anti-Corrosion Protocol:

• Pre-Shipment Treatment: Apply industrial-grade wax-based corrosion inhibitor (e.g., Dinitrol AVI 320 or equivalent) to all exposed metal surfaces.
• Coverage Areas:
• Undercarriage (tracks, rollers, idlers)
• Boom and arm pivot joints
• Hydraulic cylinder rods
• Engine compartment (non-electrical zones)
• Frame weld joints
• Application Method: High-pressure spray (15–20 bar), followed by forced-air drying.
• Film Thickness: 25–40 µm (meets ISO 9227 salt spray test standards).
• Duration of Protection: Up to 12 months in tropical marine environments.

Note: Wax film is non-drying and self-healing, providing continuous protection during vibration and minor abrasion in transit. Easily removable with industrial solvents upon delivery.

---

5. Method-Specific Risk Mitigation

Shipping Method	Corrosion Risk	Recommended Protection Enhancements
RO-RO	Medium	Full wax spray + breathable deck cover (if available)
Bulk Cargo	High	Full wax spray + VCI (Vapor Corrosion Inhibitor) bags
Flat Rack	Low–Medium	Wax spray + waterproof tarp + desiccant packs

---

6. Recommendations

Priority	Recommended Method	Rationale
Cost Efficiency	Bulk Cargo	Lowest freight cost; viable for non-sensitive destinations
Equipment Safety	Flat Rack Container	Maximum control over lashing, sealing, and corrosion protection
Speed & Volume	RO-RO	Fast turnaround at equipped ports; ideal for fleet-scale deployments
Corrosion Risk	Flat Rack + Wax Spray	Optimal protection for high-humidity or long-transit routes (e.g., S. America, SE Asia)

---

7. Conclusion

For export of the 135g excavator from China, Flat Rack Container shipping combined with industrial wax spraying provides the highest integrity solution for corrosion-prone components and is recommended for high-value or long-distance shipments. RO-RO remains optimal for cost-sensitive, high-volume operations to developed ports. Bulk Cargo is conditionally viable only when combined with rigorous anti-corrosion measures and acceptance of higher handling risk.

Fleet managers and construction logistics planners should evaluate destination port capabilities, shipment volume, and total cost of ownership (including post-arrival reconditioning) when selecting a method.
