| Coverage Areas | Undercarriage, track links, rollers, idlers, boom pins, exposed welds |
| Film Thickness | 50–75 µm (uniform coat) |
| Drying Time (Ambient 25°C) | 4–6 hours |
| Salt Spray Resistance (ASTM B117) | >1,000 hours (no red rust) |
| Repeatability | Single application sufficient for 45-day voyage |
3.2 Application Workflow
- Pre-Treatment: Degrease and dry all metal surfaces.
- Spray Application: Full coverage using robotic arms in controlled environment.
- Inspection: UV tracer verification for complete coverage.
- Documentation: Certificate of Protection issued per unit (traceable via QR code).
Compliance: Meets ISO 9227 (Corrosion Tests in Artificial Atmospheres) and CIMC Heavy Equipment Export Guidelines.
4. Recommended Logistics Strategy
| Scenario | Recommended Method | Rationale |
|---|---|---|
| High-volume fleet deployment (≥20 units) | RO-RO | Fast turnaround, low damage rate, efficient port rotation |
| Oversized models (e.g., DX520LC-5) | Flat Rack + Wax Protection | Only viable for units exceeding container dimensions |
| Budget-constrained project, non-urgent | Bulk Cargo | Lowest cost; acceptable if paired with post-arrival refurbishment |
| High-humidity or extended transit routes | RO-RO + Double Wax Coat | Enhanced corrosion defense for tropical/trans-equatorial zones |
5. Conclusion
For optimal equipment integrity, transit efficiency, and lifecycle preservation, RO-RO shipping with industrial-grade wax spraying is the preferred solution for exporting Develon excavators from China. While Bulk Cargo offers marginal cost savings, its elevated risk profile renders it unsuitable for premium machinery. Flat Rack remains a niche option for non-standard configurations but requires rigorous environmental protection protocols.
SEA LION International recommends integrating wax-based corrosion barriers into standard export SOPs across all modal choices to ensure compliance with global durability benchmarks.
