Target Audience: Fleet Managers, Construction Equipment Procurement Officers, Infrastructure Contractors
1. Executive Summary
This report evaluates three primary maritime transport methods for the export of the CAT 210-class excavator from manufacturing hubs in China (e.g., Xuzhou, Shandong) to global project sites: Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack Container Shipping. Performance is assessed across cost efficiency, transit time, equipment integrity, environmental protection, and logistical scalability. Special emphasis is placed on anti-corrosion wax spraying treatment as a mandatory pre-shipment protocol against seawater exposure.
2. Equipment Overview: CAT 210 Excavator
| Parameter | Specification |
|---|---|
| Operating Weight | 21,000–22,500 kg |
| Dimensions (L×W×H) | 9.8 m × 3.0 m × 3.3 m |
| Undercarriage Configuration | Tracked, rubber or steel pads |
| ISO Container Compatibility | Non-stackable in standard 40′ HC; requires open-top or flat rack |
| Corrosion Risk Profile | High (exposed hydraulic lines, pivot joints, undercarriage) |
3. Comparative Shipping Methodology Analysis
| Criteria | RO-RO | Bulk Cargo | Flat Rack (40′ Open Top or OTFR) |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Lifted via crane into hold | Secured on open flat rack using lashing points |
| Stowage Location | Dedicated vehicle deck (climate-controlled options) | Unprotected cargo hold; shared space | Exposed deck; top-side exposure to elements |
| Transit Time (Shanghai → Rotterdam) | 28–32 days | 35–42 days | 30–36 days |
| Port Handling Risk | Low (minimal lifting) | High (multiple crane lifts) | Medium (rigging required) |
| Weather Exposure | Low (enclosed deck) | Medium (hold humidity) | High (direct salt spray, UV) |
| Security & Vandalism Risk | Low | Medium | High |
| Average Cost per Unit (USD) | $4,200–$4,800 | $3,500–$4,000 | $5,000–$6,200 |
| Scalability (Fleet Shipments) | High (up to 50 units/voyage) | Medium (space-dependent) | Low to Medium (limited by rack availability) |
| Customs Clearance Complexity | Low (standard vehicle codes) | Medium (general cargo classification) | Medium (special handling documentation) |
| Best For | Operational units, time-sensitive deliveries | Budget-constrained, non-urgent projects | Oversized attachments, disassembled configurations |
4. Corrosion Protection: Wax Spraying Protocol
All CAT 210 units must undergo industrial-grade anti-corrosion wax encapsulation prior to shipment, regardless of transport method. SEA LION International mandates the following treatment:
- Wax Type: Solvent-based, hydrophobic polymer blend (ASTM D130-22 compliant)
- Application Method: Electrostatic spray + brush detailing
- Coverage Areas:
- Undercarriage (track links, rollers, idlers)
- Hydraulic cylinder rods
- Electrical harness connectors
- Boom/pin joints
- Engine bay (non-sensitive zones)
- Drying Time: Minimum 4 hours at 25°C before loading
- Performance: 90-day saltwater exposure resistance (per ISO 9227 NSS testing)
Note: RO-RO and Bulk Cargo benefit from partial environmental shielding, but wax treatment remains non-negotiable. Flat Rack units require double-coat application due to direct marine aerosol exposure.
5. Risk Assessment & Recommendations
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Saltwater Corrosion | Low (with wax) | Medium (condensation in hold) | High (requires enhanced wax) |
| Physical Damage | Low | High (cargo shifting) | Medium (lashing failure risk) |
| Delay Risk | Low | Medium (weather, congestion) | Medium |
| Recommended Use Case | ✅ High-value, operational fleets | ✅ Budget export, remote inland ports | ✅ Units with attachments (e.g., breakers, augers) |
6. Conclusion
For fleet managers prioritizing equipment readiness and integrity, RO-RO shipping is the optimal method for CAT 210 excavators, offering speed, reduced handling, and superior environmental control. Bulk Cargo provides a cost-effective alternative for non-urgent, high-volume shipments where minor surface corrosion is acceptable post-delivery. Flat Rack is reserved for configurations exceeding standard dimensions, though it demands rigorous wax protection and vigilant lashing.
SEA LION International enforces mandatory wax spraying across all export consignments. Non-compliant units will not be accepted for loading.
