Under real-world field testing in mixed brush and light-woodland conditions (average payload 18 m³, 60% grade operation), the system averages 30.2 L/100 km.
Key efficiency factors:
– Turbo-Intercooling: Enhances combustion efficiency, reducing specific fuel consumption (SFC) to 198 g/kWh.
– Transmission Optimization: HW19710’s wide gear spread allows sustained operation in optimal RPM band, minimizing lugging and over-revving.
– Idle Management: Standard auto-idle reduces fuel burn during mulching pauses by up to 18%.
Fleet operators report a 12–15% improvement in fuel economy compared to legacy Tier II platforms under similar duty cycles.
Load Capacity & Operational Performance
The carrier’s axle load distribution and structural frame are engineered to support high-volume mulch transport without compromising stability. With a GAWR of 36,000 kg and reinforced tandem rear axles, the system safely carries up to 22 m³ of mulched biomass (avg. density: 280 kg/m³), equating to ~6,160 kg of payload.
Critical load considerations:
– Center of Gravity (CoG): Optimized for rear-weighted loads; mulch body design includes hydraulic tailgate retention.
– Tire Performance: 12.00R20 radial tires provide low ground pressure (1.4 MPa at rated load), reducing soil compaction on sensitive sites.
– On-Site Maneuverability: Turning radius of 7.8 m enables operation in confined forest corridors and urban redevelopment zones.
Conclusion
The excavator mulching head system, configured with the Weichai WD615 engine, HW19710 transmission, and 12.00R20 off-road tires, delivers a balanced solution for high-capacity, fuel-efficient land management. Designed for 20,000-hour service life with scheduled maintenance, this configuration meets the operational demands of large-scale construction and rights-of-way maintenance fleets. Integration with telematics for fuel monitoring and axle load feedback is recommended for maximum fleet optimization.

Executive Summary
This report provides a technical and operational comparison of three primary maritime shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container transport—for the export of excavator mulching heads (EMH) from manufacturing hubs in China (e.g., Qingdao, Shanghai, Nansha) to global construction project sites. Key evaluation criteria include cargo protection, handling efficiency, cost structure, transit reliability, and corrosion mitigation. Special emphasis is placed on the implementation of wax-based anti-corrosion coatings to protect high-value steel components during ocean transit.
1. Product Overview: Excavator Mulching Head (EMH)
| Parameter | Specification |
|---|---|
| Weight Range | 1,800 – 4,200 kg |
| Dimensions (L×W×H) | 2.1 m × 1.4 m × 1.6 m (avg.) |
| Material Composition | High-strength alloy steel (hardfaced cutting blades) |
| Corrosion Sensitivity | High (exposed gearboxes, pivot joints, hydraulic ports) |
| Handling Requirements | Forklift or crane lift points; no self-propulsion |
Note: EMHs are precision-engineered attachments used in land clearing and forestry operations. Surface integrity and mechanical alignment are critical for post-shipment performance.
2. Shipping Method Comparison
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo | Flat Rack Container |
|---|---|---|---|
| Cargo Compatibility | Suitable if EMH is mounted on tracked carrier (e.g., excavator). Not ideal for standalone heads. | Accepts irregular loads; requires dunnage and lashing. Risk of shifting. | Optimal for oversized, non-wheeled machinery. Full structural support. |
| Loading/Unloading Speed | Fast (driven or towed on/off vessel) | Slow (requires crane and rigging at both ends) | Moderate (requires crane but standardized lashing points) |
| Transit Protection | Moderate. Exposed decks increase salt spray exposure. Limited weather shielding. | Low. Cargo stowed in hold but subject to condensation and moisture ingress. | High. Can be wrapped and sealed; optional tarping or container enclosure. |
| Security & Vandalism Risk | Medium (open decks, multi-client cargo) | High (commingled stowage) | Low (dedicated unit, lockable lashings) |
| Cost (USD/unit, Shanghai → Rotterdam) | $1,100 – $1,600 | $900 – $1,300 | $1,800 – $2,400 |
| Transit Time Reliability | High (scheduled services) | Variable (dependent on charter and port congestion) | High (containerized, fixed schedules) |
| Port Infrastructure Requirements | RO-RO ramps and certified tow vehicles | Heavy-lift cranes, laydown area | Container cranes, flat rack availability |
| Best Use Case | EMH shipped pre-installed on excavator | Low-cost, non-urgent bulk shipments with other machinery | High-value, corrosion-sensitive standalone units |
3. Corrosion Protection: Wax Spraying Protocol
Saltwater exposure during ocean transport poses a significant risk to the metallurgical integrity of EMH components, particularly gearboxes, pivot pins, and hydraulic interfaces.
Recommended Anti-Corrosion Treatment:
- Method: Automated electrostatic wax spraying (synthetic hydrophobic compound)
- Product Type: Solvent-free, biodegradable corrosion inhibitor (e.g., Lanocote®-equivalent)
- Coating Thickness: 25–50 µm (uniform coverage)
- Application Points:
- Cutting drum assembly
- Gearbox housing vents and seals
- Hydraulic quick-connect fittings
- Pivot shafts and bearing housings
- Post-Treatment: Air-dry for 2 hours; wrap critical zones with VCI (Vapor Corrosion Inhibitor) film before loading
Performance Data: Wax coating reduces salt spray-induced oxidation by ≥92% over 45-day ocean voyage (per ASTM B117 accelerated testing).
4. Method-Specific Recommendations
RO-RO
- Applicable only when EMH is part of a complete excavator unit.
- Apply wax spray and seal hydraulic lines with caps and VCI plugs.
- Use deck-side moisture barriers if available.
- Not recommended for standalone EMH due to inadequate securing and exposure.
Bulk Cargo
- High risk of corrosion and physical damage.
- Mandatory: Full wax spray + shrink-wrapping on wooden skid.
- Dunnage must elevate unit ≥30 cm from bilge moisture.
- Lashing to ISO standard (DNVGL-ST-0378).
- Suitable only for cost-driven projects with acceptable risk tolerance.
Flat Rack Container
- Recommended method for standalone EMH exports.
- Enables full environmental encapsulation.
- Wax spraying + tarping + desiccant packs inside frame enclosure.
- Lashing points aligned with DNV 2.7-1 standards.
- Enables tracking via container GPS/temperature/humidity sensors.
5. Cost-Benefit Analysis (Per Unit, Shanghai → West Mediterranean)
| Metric | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Base Freight Cost | $1,350 | $1,100 | $2,100 |
| Protection & Prep Cost | $180 | $250 | $320 |
| Risk-Adjusted Downtime Cost (est.) | $400 | $900 | $150 |
| Total Effective Cost | $1,930 | $2,250 | $2,570 |
| Recommended Use | Conditional | Limited | Preferred |
Note: Risk-adjusted downtime includes rework, replacement parts, and project delays due to corrosion or damage.
6. Conclusion & Recommendation
For the export of standalone excavator mulching heads from China, Flat Rack container shipping combined with industrial-grade wax spraying provides the optimal balance of protection, reliability, and long-term cost efficiency. While initial freight costs are higher, the reduction in corrosion-related failures and warranty claims results in lower total cost of ownership.
SEA LION International recommends:
- Adopt Flat Rack transport for all high-value, corrosion-sensitive EMH shipments.
- Implement standardized wax spraying at point of origin using ISO 9001-certified facilities.
- Require VCI film encapsulation and lashing certification for all ocean movements.
- Avoid Bulk Cargo unless under strict cost mandates with accepted risk provisioning.
