Corrosion Risk Assessment
All three methods expose equipment to salt-laden marine atmospheres. Critical risk zones include:
- Steel undercarriage and track links
- Unpainted weld joints
- Hydraulic cylinder rods
- Electrical connectors and control boxes
Observed Corrosion Onset:
Without protection, visible oxidation occurs within 72 hours of seawater exposure. After 14 days, pitting corrosion can compromise structural integrity.
Wax Spraying Protection Protocol
To mitigate seawater-induced corrosion during transit, industrial-grade wax spraying is strongly recommended as a preventive measure prior to shipment.
Specification: Wax Coating System
| Parameter | Requirement |
|---|---|
| Product Type | Solvent-based, hydrophobic corrosion-inhibiting wax |
| Application Method | High-pressure spray (2,000–3,000 psi) |
| Coverage Areas | Entire undercarriage, joints, hydraulic components, exposed metal surfaces |
| Film Thickness | 50–75 µm (dry) |
| Drying Time | 2–4 hours (ambient 25°C) |
| Salt Spray Resistance (ASTM B117) | >500 hours |
| Removal Method | Biodegradable degreaser or steam cleaning |
Application Timing: Within 24 hours of final assembly and prior to transport to port.
Certification: ISO 12944-2 compliant for C5-M (marine corrosive environment).
Method Recommendation by Use Case
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Multiple units, operational status | RO-RO | Fast loading, low handling risk, cost-effective for volume |
| Disassembled units, cost-sensitive | Bulk Cargo | Lowest cost; optimal for non-functional equipment |
| Oversized or non-movable units | Flat Rack | Only viable option for non-rollable, wide/heavy configurations |
Universal Recommendation: Apply wax spraying regardless of shipping method.
Conclusion
For the reliable export of excavator flail mowers from China, RO-RO shipping offers the best balance of cost, speed, and safety for operational units, while Flat Rack remains essential for non-roadworthy configurations. Bulk Cargo is viable only when cost is paramount and equipment is disassembled.
Critical Success Factor: Implementation of wax spraying corrosion protection is non-negotiable for all shipments. SEA LION International recommends integrating wax treatment into OEM pre-shipment protocols to ensure equipment arrives in commission-ready condition.
