– Thermal Shock Test: 50 cycles from -30°C to 110°C coolant temp. Zero seal failures or head gasket leaks.
– Oil Analysis (at 500 hrs): Ferrous wear < 50 ppm (spectrometric oil analysis program/SOAP threshold: 120 ppm).
3. PRE-DELIVERY INSPECTION (PDI) PROTOCOL
All units undergo SEA LION-certified PDI at distribution hubs. Non-compliant units are quarantined until rework. Critical checks for terrain/engine resilience:
| Inspection Phase | Key Parameters | Pass/Fail Threshold | Tool/Method |
|---|---|---|---|
| Chassis Integrity | Track frame alignment tolerance | ≤ ±1.5 mm | Laser theodolite |
| Slew ring backlash | ≤ 0.8 mm | Dial indicator | |

| Oil pressure @ 1,500 RPM | 4.2–5.0 bar | ISO 1585 Annex C | |
| Exhaust gas temperature (EGT) variance | ≤ ±15°C across cylinders | Thermocouple array | |
| Dynamic Test | Vibration amplitude (cab floor) | ≤ 2.5 m/s² RMS | ISO 2631-1 compliant |
| Hydraulic response lag (boom/dipper) | ≤ 0.35 sec | High-speed camera (120 fps) |
Note: All PDI data is digitally logged to Doosan Connect™ telematics; accessible via fleet management portal.
CONCLUSION FOR FLEET OPERATIONS
The DX300LC-5 series demonstrates quantifiable superiority in chassis resilience and engine longevity under validated severe-duty conditions. SEA LION International’s PDI protocol ensures only units meeting the above thresholds enter service, directly reducing unplanned downtime by 22% (per 2025 fleet data). For construction companies operating in high-abrasion, high-vibration environments, this represents a critical TCO advantage through extended service intervals and minimized structural repair costs. SEA LION recommends mandatory PDI compliance verification prior to fleet acceptance.

Shipping & Logistics Solutions
Industrial Specification Report 2026
Prepared for: Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Doosan Excavators from China
Date: January 2026
Prepared by: SEA LION International – Heavy Equipment Logistics Division
Executive Summary
This report outlines the optimal logistics solutions for the export of Doosan excavators from manufacturing hubs in China (e.g., Shandong, Jiangsu) to global construction markets. Three primary shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—are evaluated based on cost, transit time, equipment integrity, and environmental protection. Special emphasis is placed on corrosion prevention via industrial wax spraying, a critical measure for long-sea transport through high-humidity and saline environments.

| Transit Time | 25–35 days (direct routes) | 30–45 days (port congestion risk) | 28–40 days (standard container routing) |
| Cost (USD/unit) | $3,800 – $4,500 | $3,200 – $3,800 | $5,200 – $6,000 |
| Damage Risk | Medium (deck movement, salt spray) | High (shifting, moisture ingress) | Low (controlled environment, bracing) |
| Port Infrastructure | Requires RO-RO-capable terminals | Standard bulk terminals | Standard container terminals |
| Customs Clearance | Faster (pre-staged documentation) | Slower (inspection delays common) | Streamlined (ISO container compliance) |
| Best For | High-volume, time-sensitive shipments | Cost-sensitive, non-urgent consignments | High-value units, corrosion-prone regions |
3. Corrosion Protection: Wax Spraying Protocol
Marine environments pose a significant risk of saltwater-induced corrosion to hydraulic systems, undercarriages, and unpainted metal surfaces. SEA LION International implements an industrial-grade wax spraying process compliant with ISO 12944-6:2018 (Corrosion Protection of Steel Structures).
Wax Spraying Specifications:
| Parameter | Specification |
|---|---|
| Coating Type | Solvent-based synthetic rust-inhibitive wax |
| Application Method | High-pressure spray (12–15 bar) |
| Coverage Areas | Undercarriage, boom/pivot joints, track links, radiator fins, hydraulic cylinders |
| Film Thickness | 50–70 µm (microns) |
| Salt Spray Resistance | 1,000+ hours (ASTM B117 tested) |
| Removal Process | Biodegradable citrus-based solvent; no residue |
| Certification | SGS TÜV-certified; compliant with IMO A.754(18) |
Note: Wax application is mandatory for all units shipped via RO-RO and Bulk Cargo; recommended for Flat Rack in tropical maritime zones.
4. Risk Assessment & Mitigation
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack | Mitigation Strategy |
|---|---|---|---|---|
| Seawater Exposure | High | Very High | Medium | Wax spray + desiccant bags in cab |
| Mechanical Impact | Medium | High | Low | Steel bracing, anti-vibration mounts |
| Theft/Vandalism | Low | Medium | Low | GPS tracking, sealed load reports |
| Delayed Customs | Low | High | Medium | Pre-cleared documentation, bonded transit |
| Port Handling Damage | Medium | High | Low | Certified stevedores, load supervision |
5. Recommendations
-
For Time-Sensitive, High-Volume Fleets:
→ Utilize RO-RO shipping with mandatory wax spraying. Optimal for fleet rollouts in GCC or ASEAN markets. -
For Budget-Constrained Projects with Flexible Timelines:
→ Consider Bulk Cargo, but only with full disassembly, enclosed packaging, and enhanced wax coating. Not recommended for coastal sites with high humidity. -
For Premium Units or Corrosive Environments:
→ Flat Rack containers are the preferred method. Offers maximum protection, traceability, and compliance with international handling standards.
6. Conclusion
Exporting Doosan excavators from China demands a strategic alignment of shipping mode, environmental protection, and cost efficiency. While RO-RO offers speed and scalability, Flat Rack provides superior asset protection—especially when combined with industrial wax spraying. SEA LION International recommends a hybrid logistics model, tailoring the method to destination climate, project urgency, and fleet value.
All shipments are monitored via IoT-enabled tracking, with real-time humidity and shock sensors to ensure integrity throughout the supply chain.
