| Application Method | Electrostatic spray + brush detailing |
| Coverage Areas | Undercarriage, boom/pin joints, radiator fins, hydraulic cylinders, track links, electrical junctions |
| Thickness | 50–75 µm (DFT) |
| Salt Spray Resistance | >1,000 hours (ASTM B117) |
| Removability | Biodegradable solvent-based remover (non-abrasive) |
| Application Point | Pre-shipment at OEM facility or certified CFS (Container Freight Station) |
Note: Wax film remains effective for up to 120 days at 85% RH and 35°C. Post-discharge removal is required before commissioning.
4. Method-Specific Recommendations
RO-RO
- Best for: High-value, operational machines requiring fast deployment.
- Advantage: Minimal handling, faster port turnaround.
- Constraint: Limited to ports with RO-RO infrastructure.
Bulk Cargo
- Best for: High-volume, non-operational units; cost-sensitive projects.
- Risk: Higher moisture retention in holds increases corrosion potential.
- Mitigation: Mandatory wax spray + silica gel desiccants in sealed cabs.
Flat Rack
- Best for: Oversized excavators (>3.2m width), custom configurations.
- Advantage: Full visibility and access for inspection during transit.
- Constraint: Requires tarpaulin cover; additional lashing certification.
5. Total Cost of Ownership (TCO) Analysis (5-Year Projection)
| Cost Factor | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Base Freight | $4,800 | $3,900 | $5,600 |
| Wax Protection | $320 | $320 | $320 |
| Insurance (5 yrs) | $2,100 | $2,730 | $2,310 |
| Expected Repair (Corrosion/Damage) | $1,400 | $3,200 | $1,800 |
| 5-Yr TCO | $8,620 | $10,150 | $10,030 |
Conclusion: RO-RO offers the lowest TCO despite higher base freight, due to reduced damage and maintenance.
6. Final Recommendations
- Primary Method: RO-RO for standard and high-utilization excavators.
- Secondary Option: Flat Rack for non-standard or oversized units.
- Avoid Bulk Cargo unless cost is overriding and units are stripped-down.
- Enforce Wax Spraying: Apply at origin; document conformance in shipping manifest.
- Audit Compliance: Conduct pre-shipment QA at Chinese CFS with third-party verification.
