• Emission Compliance: Meets Tier 4 Final / China V standards via integrated DOC + SCR aftertreatment.
• Smart Power Management: The HW19710 transmission synchronizes with engine load sensing to reduce parasitic losses, enhancing fuel economy during repetitive cycle operations.

---

Load Capacity & Structural Performance

The 470 excavator is engineered for high-capacity earthmoving and heavy-duty quarry applications. Its load distribution and structural integrity are validated under maximum breakout force conditions:

• Maximum Digging Force: 305 kN (bucket), 265 kN (arm)
• Payload Capacity (Bucket): 3.8 m³ (standard bucket), up to 5.2 m³ (heavy-duty rock bucket)
• Axle Load Distribution: Balanced front-to-rear ratio (52:48) ensures stability on uneven terrain and reduces tire wear.
• Tire Performance: The 12.00R20 radial tires offer high load-carrying capacity (3,650 kg per tire at 85 psi), cut/chip resistance, and extended tread life under abrasive site conditions.

Note: Continuous operation at >90% of rated load reduces component service life by up to 25%. Recommended duty cycles include 10-minute cooldown intervals after 90 minutes of peak loading.

---

Operational Recommendations

• Transmission Use: HW19710 provides smooth gear engagement; avoid abrupt shifting under load to maximize clutch life.
• Tire Maintenance: Maintain inflation pressure at 85 psi; inspect monthly for uneven wear or casing damage.
• Fuel Strategy: Use ultra-low sulfur diesel (ULSD) with cetane ≥ 50 for optimal combustion and aftertreatment protection.

---

Conclusion: The 470 excavator delivers high power density, robust load handling, and improved fuel economy, making it suitable for large-scale infrastructure and mining operations. Its Weichai WD615 engine and HW19710 transmission provide reliable performance in continuous heavy-duty service.

Executive Summary

This report provides a comparative analysis of three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of the ‘470 Excavator’ from manufacturing hubs in China to international construction markets. The evaluation focuses on cost efficiency, transit reliability, equipment integrity, and corrosion protection, with specific emphasis on wax-based anti-corrosion treatments for seawater exposure.

The ‘470 Excavator’, a high-capacity heavy-duty machine (approx. 47 metric tons, dimensions: 12.1 m L × 3.5 m W × 3.8 m H), presents unique logistical challenges due to its weight, operational sensitivity, and exposure risk during ocean transit. This report evaluates the optimal shipping method based on operational and technical criteria.

---

1. Shipping Method Overview

Method	Description	Suitability for 470 Excavator
RO-RO	Vessels with ramps allowing self-propelled or towed equipment roll-on/roll-off	High – if machine is operational
Bulk Cargo	Loose stowage in hold; secured with lashing; no containerization	Moderate – risk of surface damage
Flat Rack	Open-top, collapsible-side containers; secured on deck or in hold	High – optimal for oversized machinery

---

2. Comparative Analysis

Criteria	RO-RO Shipping	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or winch-assisted	Crane-lifted into hold	Crane-lifted onto flat rack
Equipment Protection	Moderate (exposed decks)	Low (direct hold exposure)	High (weatherproofed, secured)
Transit Time (avg.)	28–35 days (direct routes)	30–40 days	28–38 days
Port Infrastructure	Requires RO-RO terminal	Standard bulk terminal	Standard container terminal
Damage Risk	Medium (deck movement)	High (chafing, moisture)	Low (reinforced lashing points)
Cost (USD/unit)	$14,500 – $17,000	$11,000 – $13,500	$18,000 – $21,000
Insurance Premium	Moderate	High	Low to Moderate
Customs Clearance	Straightforward	Complex (bulk manifests)	Standard container process
Environmental Exposure	High (salt spray, humidity)	Very High	Controlled (with sealing)

Note: Cost estimates based on Shanghai to Rotterdam route, Q1 2026 freight indices.

3. Corrosion Protection: Wax Spraying Treatment

Marine environments expose heavy equipment to salt-laden air and condensation, accelerating corrosion on hydraulic components, undercarriages, and unpainted metal surfaces.

Recommended Protection Protocol:

• Pre-Shipment Treatment: Full-machine application of hydrophobic, solvent-based corrosion-inhibiting wax (e.g., lanolin-derived or synthetic polymers).
• Application Method: Electrostatic or pressurized spray ensuring coverage of joints, tracks, boom hinges, and recessed areas.
• Thickness: 25–50 µm dry film thickness.
• Duration: Effective protection for up to 6 months under maritime conditions.
• Post-Transit: Wax is non-drying and removable with industrial degreasers; does not interfere with commissioning.

Benefits:

• Prevents chloride-induced pitting on steel components.
• Reduces maintenance downtime post-delivery.
• Complies with ISO 9223 Corrosivity Category C4 (industrial/marine zones).

Best Practice: Apply wax treatment within 48 hours of final assembly and prior to transport staging.

---

4. Method Recommendation

Method	Recommended Use Case
RO-RO	For operational units destined to ports with RO-RO infrastructure; cost-sensitive, time-critical shipments.
Bulk Cargo	Not recommended for 470 Excavator due to high damage and corrosion risk. Avoid unless cost is overriding.
Flat Rack	Preferred method – maximizes protection, enables full corrosion treatment sealing, and simplifies handling. Ideal for sensitive or high-value units.

---

5. Conclusion

For fleet managers and construction enterprises importing the ‘470 Excavator’ from China, Flat Rack container shipping is the optimal logistics solution, balancing equipment safety, corrosion control, and long-term cost of ownership. RO-RO remains a viable alternative for operational units moving to compatible ports, provided wax-based anti-corrosion treatment is rigorously applied. Bulk cargo transport is discouraged due to unacceptable exposure and handling risks.

SEA LION International recommends integrating wax spraying protocols into OEM pre-shipment procedures and selecting Flat Rack logistics for critical deliveries to ensure machine readiness upon arrival.
