Performance Overview
Fuel Efficiency
The Weichai WD615.62G engine is engineered for high torque output and optimized combustion efficiency. Integrated with electronic unit pump (EUP) fuel injection and a high-efficiency turbocharger, the SH460H-6 achieves an average fuel consumption of 28–32 L/h (7.4–8.5 gal/h) under standard excavation cycles (digging, swinging, loading). At continuous travel on haul roads, fuel usage drops to 22–25 L/h due to the HW19710 transmission’s wide gear ratio spread and reduced engine load in higher gears.
Advanced engine calibration and load-sensing hydraulic systems contribute to a 12–15% improvement in fuel economy compared to previous-generation models, making it ideal for long-duration operations in quarrying and large-scale civil projects.
Load Capacity & Structural Integrity
With a total operating weight of 46 tonnes and a balanced 6×4 axle configuration, the SH460H-6 is designed for maximum payload stability and reduced ground pressure. The lift axle (when deployed) allows dynamic load redistribution, enabling compliance with regional road weight regulations during transit.
- Maximum Digging Depth: 7,800 mm
- Maximum Reach at Ground Level: 11,200 mm
- Swing Torque: 68,500 Nm
- Drawbar Pull: 310 kN
The excavator’s reinforced undercarriage and heavy-duty swing bearing support sustained operation in high-impact environments, including rock excavation and heavy material handling.
The 12.00R20 tires are selected for their high load index (150/147), cut-resistant tread compound, and heat dispersion characteristics—critical for maintaining performance on rough terrain and extended haul routes. These tires support continuous loads up to 5,500 kg per tire under optimal pressure (85 psi).
Conclusion
The Sumitomo SH460H-6, powered by the Weichai WD615 engine and paired with the HW19710 transmission, delivers industrial-grade reliability, superior load management, and measurable fuel savings. Its axle and tire configuration ensures compliance with transport standards while maximizing on-site productivity. Recommended for large-scale earthmoving, mining support, and infrastructure development fleets requiring durability and operational efficiency.

1. Executive Summary
This report evaluates optimal maritime logistics methodologies for the export of Sumitomo excavators from manufacturing hubs in China (e.g., Shanghai, Qingdao, Nantong) to global construction markets. Three primary shipping modalities—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container transport—are analyzed based on cost, equipment integrity, transit time, and environmental protection. Special emphasis is placed on corrosion mitigation through wax-based anti-seawater coatings, a critical factor in ensuring long-term equipment performance post-transit.

Note: Dimensions and weight are representative; actual values may vary by model and configuration.
3. Shipping Method Comparison
The following table compares RO-RO, Bulk Cargo, and Flat Rack shipping methods across key operational and logistical parameters:
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Lo-Lo) | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Lifted by ship’s crane or port gantry | Secured via lashing on open platform container |
| Equipment Protection | Moderate (exposed decks; partial weather cover) | Low (exposed to salt, moisture, debris) | High (customizable lashing, full wax spray compatibility) |
| Corrosion Risk | High (direct seawater spray, humidity) | Very High (prolonged exposure) | Low (with wax protection + shrink-wrapping) |
| Transit Time | Fast (direct loading/unloading) | Moderate (port congestion common) | Moderate to Fast (containerized handling) |
| Port Infrastructure Required | RO-RO ramps and clear approach paths | Heavy-lift cranes, laydown areas | Standard container terminals |
| Cost (USD/unit, Shanghai → Rotterdam) | $4,800 – $5,500 | $3,900 – $4,300 | $6,200 – $7,000 |
| Insurance Complexity | Moderate | High (damage risk) | Low (standard container clauses apply) |
| Suitability for Multiple Units | High (fleet roll-on) | Medium (stacking not feasible) | Medium (limited by container availability) |
| Customs Clearance | Straightforward | Complex (break-bulk documentation) | Streamlined (containerized ISF, AMS) |
4. Corrosion Mitigation: Wax Spraying Protection Protocol
Marine transport exposes heavy machinery to high-salinity environments, accelerating oxidation of hydraulic components, undercarriages, and structural steel. SEA LION International recommends the Wax-Based Anti-Corrosion Spray System (WACS-2026) as a mandatory pre-shipment treatment.
4.1 WACS-2026 Application Process
| Step | Procedure | Duration | Coverage Target |
|---|---|---|---|
| 1 | Surface cleaning (degrease, dry) | 45 min | All metal surfaces, joints, undercarriage |
| 2 | Apply hydrophobic wax emulsion (solvent-free) | 30 min | 100 µm dry film thickness |
| 3 | Secondary coating on pivot points & seals | 15 min | Pin joints, track links, boom hinges |
| 4 | Shrink-wrap cabin and control panel | 20 min | Electronics, glass, seat assembly |
| 5 | Final inspection & certification | 10 min | QA/QC compliance log |
Wax formulation: Paraffin-based polymer blend with volatile corrosion inhibitors (VCI). Removable via standard degreaser upon delivery.
4.2 Performance Metrics (ASTM G1-03)
| Test Parameter | Result |
|---|---|
| Salt Spray Resistance (ASTM B117) | 500+ hours no red rust |
| Humidity Exposure (85% RH, 40°C) | 30 days protection |
| Adhesion (Cross-hatch test) | 5B (no peeling) |
| Temperature Range | -20°C to +80°C |
5. Recommended Shipping Method by Use Case
| Application | Recommended Method | Rationale |
|---|---|---|
| Large Fleet Export (10+ units) | RO-RO with WACS-2026 | Fast turnaround, cost/unit efficient, scalable |
| Single Unit to Non-RO-RO Port | Flat Rack + Wax Spray | Maximum protection, compatibility with standard ports |
| Budget-Constrained, Short Sea Route | Bulk Cargo (with WACS-2026 + tarpaulin) | Lowest cost; acceptable risk with mitigation |
| High-Value or Cold-Climate Destinations | Flat Rack + Full Enclosure | Prevents condensation and freeze-corrosion |
6. Operational Recommendations
- Pre-Shipment Protocol: All excavators must undergo WACS-2026 treatment prior to loading, regardless of shipping method.
- Lashing Standards: For Flat Rack, comply with CSS Code and ISO 1496-4. Use ≥ 4-point lashing with 8,000 kg SWL straps.
- Vessel Selection: Prioritize vessels with enclosed decks or climate-controlled holds where available.
- Tracking & Monitoring: Install IoT vibration/humidity loggers for units in transit (optional add-on).
7. Conclusion
For the reliable export of Sumitomo excavators from China, RO-RO shipping with wax-based corrosion protection offers the optimal balance of speed, scalability, and cost for fleet operators. Flat Rack transport is superior in equipment integrity and is recommended for high-value or remote deliveries. Bulk Cargo remains a cost-effective option only when paired with rigorous anti-corrosion measures.
SEA LION International advocates standardized implementation of the WACS-2026 protocol across all export shipments to minimize post-delivery maintenance and ensure operational readiness upon arrival.
