Shipping & Logistics Solutions

Industrial Specification Report 2026
Prepared for: Fleet Managers & Construction Companies
Subject: Export Logistics Solutions for CAT 320C Excavator from China
Issuing Authority: SEA LION International – Engineering & Logistics Division
Date: January 2026
Executive Summary
This report evaluates industrial-grade logistics methodologies for the export of used Caterpillar 320C Hydraulic Excavators from manufacturing and consolidation hubs in China to global construction markets. Three primary shipping modalities—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack (Containerized)—are analyzed based on cost, security, transit time, equipment integrity, and environmental protection. Special emphasis is placed on anti-corrosion measures, particularly wax-based protective coatings, to mitigate seawater exposure during marine transit.
1. Equipment Profile: CAT 320C Excavator
| Parameter | Specification |
|---|---|
| Operating Weight | 20,300 kg (44,750 lb) |
| Length (with bucket) | 9.7 m (31.8 ft) |
| Width | 2.9 m (9.5 ft) |
| Height (transport) | 3.0 m (9.8 ft) |
| Undercarriage Condition | Track tension, shoe wear, roller state |
| Fluid Reservoirs | Drained (fuel, hydraulic oil, coolant) |
| Corrosion Risk Zones | Undercarriage, boom/pin joints, cab base |
Note: Excavators are classified as heavy construction equipment (HCE) with high susceptibility to saltwater-induced corrosion, especially in coastal shipping zones.
2. Comparative Shipping Modalities
| Criteria | RO-RO Shipping | Bulk Cargo | Flat Rack (20′ or 40′) |
|---|---|---|---|
| Loading Method | Self-propelled or towed on deck | Lifted via crane into hold | Secured on open-top flat rack container |
| Equipment Protection | Moderate (exposed to weather/spray) | Low (confined but humid environment) | High (controlled lashings, visibility) |
| Transit Time (China → MENA/EU/SEA) | 14–21 days | 21–30 days | 16–24 days |
| Average Cost (per unit) | $2,800 – $3,500 | $2,200 – $3,000 | $3,800 – $4,600 |
| Security & Monitoring | Limited visibility; shared deck space | High risk of shifting; no real-time access | Full visibility; ISO lashing standards |
| Damage Risk | Medium (vibration, moisture) | High (condensation, handling impact) | Low (if properly secured) |
| Port Infrastructure Needs | RO-RO ramp-equipped terminals only | General cargo cranes required | Standard container handling |
| Best Suited For | Operational units, low-cost priority | Non-operational, stripped units | High-value, corrosion-sensitive units |
Key Insight: While Bulk Cargo offers the lowest cost, it presents the highest risk of structural and cosmetic degradation. Flat Rack provides superior control over securing and inspection but at a 30–40% cost premium over RO-RO.
3. Anti-Corrosion Protocol: Wax Spraying Protection
Marine environments expose ferrous components to chloride-laden aerosols, accelerating oxidation. SEA LION International mandates industrial-grade wax spraying for all excavators shipped from coastal Chinese ports (e.g., Shanghai, Ningbo, Qingdao).
Wax Protection Specifications:
| Parameter | Requirement |
|---|---|
| Coating Type | Solvent-based, hydrophobic microcrystalline wax |
| Application Method | High-pressure spray (20–30 bar) |
| Coverage Areas | Undercarriage, track links, rollers, idlers, boom hinge pins, cab underside |
| Thickness | 50–70 µm (measured via DFT gauge) |
| Drying Time | 4–6 hours (ambient 25°C) |
| Salt Spray Resistance | 500+ hours (ASTM B117 compliance) |
| Removal Process | Biodegradable citrus-based solvent; no residue |
Process Flow:
1. Pre-treatment: High-pressure freshwater rinse + degreasing
2. Drying: Compressed air blow-off + ambient drying
3. Wax application: Robotic or manual spray in climate-controlled bay
4. Final inspection: Coating thickness and coverage auditEffectiveness: Reduces post-transit rust incidence by ≥85% in 40-day voyages across the South China Sea and Indian Ocean.
4. Recommended Logistics Strategy
| Scenario | Recommended Method | Rationale |
|---|---|---|
| Multiple operational units, cost-sensitive | RO-RO + Wax Protection | Balanced cost, faster turnaround, moderate protection with wax mitigation |
| Non-operational or salvage units | Bulk Cargo | Lowest cost; acceptable for rebuild markets |
| High-value, corrosion-prone units (humid destinations) | Flat Rack + Wax Spray | Maximum protection, full visibility, ISO-compliant securing |
Compliance Note: All shipments must adhere to IMDG Code (Class 9 – Machinery) and CTU (Cargo Transport Unit) Code for securement.
5. Conclusion
For export of CAT 320C excavators from China, Flat Rack shipping combined with industrial wax spraying delivers optimal protection for long-haul logistics to tropical and coastal construction zones. RO-RO remains viable for operational units where cost efficiency is prioritized, provided wax protection is uniformly applied. Bulk Cargo is discouraged except for non-functional units destined for immediate refurbishment.
SEA LION International recommends implementing mandatory pre-shipment wax encapsulation across all modalities to ensure equipment integrity and reduce post-delivery reconditioning costs.
