| Application Method | High-pressure spray (15–20 bar) |
| Coverage Areas | Undercarriage, track links, boom pins, exposed welds, radiator fins |
| Film Thickness | 50–75 µm (dry) |
| Salt Spray Resistance | >500 hours (ASTM B117) |
| Residual Protection | Up to 6 months post-discharge |
| Removal Process | Biodegradable solvent wash at destination |
4.2 Application Workflow
- Pre-Treatment: Clean all surfaces with degreaser; dry with compressed air.
- Masking: Protect air intakes, sensors, and exhaust ports.
- Spraying: Apply uniform coat; focus on crevices and joints.
- Curing: Allow 4–6 hours at 25°C before loading.
- Verification: Conduct coating thickness audit (per ISO 2808).
Note: Wax spraying is mandatory for all Sunward Excavators shipped via sea routes. RO-RO and Flat Rack units require full undercarriage coverage due to deck exposure.
5. Recommendations
| Shipping Method | Recommended Use Case | Conditions for Selection |
|---|---|---|
| RO-RO | Preferred for destinations with RO-RO terminals | High volume, time-sensitive, premium service |
| Bulk Cargo | Only if cost is primary driver and port lacks alternatives | Accept higher risk of corrosion and damage |
| Flat Rack | For non-standard dimensions or inland delivery via rail | When RO-RO unavailable; budget allows premium |
6. Conclusion
For optimal protection, cost-efficiency, and operational reliability, RO-RO shipping is the recommended method for exporting the Sunward Excavator from China. It offers superior handling control, reduced mechanical risk, and streamlined logistics. Flat Rack is viable for oversized configurations, while Bulk Cargo is discouraged due to elevated corrosion and damage exposure.
Mandatory wax spraying must be implemented across all shipping modes to ensure equipment integrity upon arrival. SEA LION International enforces compliance with ISO 9001 and IMO CSC standards in all export operations.
