Fuel Efficiency Analysis
The Weichai WD615 engine is optimized for fuel-efficient operation under variable load conditions typical in excavation and loading cycles. Integrated with an electronically managed high-pressure common rail (HPCR) fuel system, the engine delivers precise fuel injection, resulting in:
- Average Fuel Consumption: 28–32 L/hr under mixed operating conditions (digging, swinging, loading).
- Idle Fuel Savings: Auto-idle shutdown and low-idle mode reduce consumption by up to 18% during non-productive cycles.
- Load-Sensing Hydraulic System: Reduces parasitic losses by matching pump output to demand, improving overall system efficiency by ~12% vs. fixed displacement systems.
Independent field trials across quarry and urban construction sites show a 15–20% reduction in fuel cost per m³ moved compared to legacy CAT 320 units without modern hydraulics.
Load Capacity & Structural Performance
The XE320E is engineered for high-cycle material handling with robust structural integrity:
- Maximum Digging Force (Stick): 152 kN
- Maximum Digging Force (Bucket): 178 kN
- Static Ground Pressure: 56 kPa (8.1 psi) with standard track configuration
- Payload Stability: Verified through FEA analysis and ISO 10968 compliance testing; safe operation up to 85% of tipping load under ISO 9926 conditions.
The HW19710 transmission ensures smooth power delivery across gradients up to 30%, with reinforced final drives and wet disc brakes for extended service life in high-dust and wet environments.
Tire specification 12.00R20 offers:
– High puncture resistance with cut- and abrasion-resistant tread compound
– Load capacity of 3,650 kg per tire at 85 psi (590 kPa)
– Optimized for on-site mobility and transport between project locations
Conclusion
The XE320E platform delivers CAT 320-level performance with improved total cost of ownership through the integration of the Weichai WD615 engine and HW19710 transmission. With strong load capacity, proven fuel efficiency, and rugged tire and axle specifications, this machine is ideally suited for fleet deployment in infrastructure, mining, and large-scale civil construction operations.

| Insurance Complexity | Standard (low claim rate) | Higher (cargo shifting risk) | Moderate (weather exposure) |
| Best Suited For | High-volume fleet shipments | Mixed equipment cargo | Oversized or non-roadable units |
4. Corrosion Protection: Wax Spraying Protocol
Seawater and high-humidity marine environments pose a significant risk to excavator undercarriages, hydraulic components, and steel surfaces during transit. SEA LION International recommends industrial-grade wax-based anti-corrosion treatment as a mandatory pre-shipment process.
Wax Spraying Specifications:
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-based, hydrophobic polymer blend |
| Application Method | High-pressure spray (15–20 bar) |
| Coverage Areas | Undercarriage, track links, rollers, boom pins, hydraulic rod seals, battery tray |
| Film Thickness | 30–50 µm (dry film) |
| Salt Spray Resistance | >1,000 hours (ASTM B117) |
| Removal Process | Biodegradable solvent wash post-delivery |
| Certification | ISO 9227, DIN 50017 |
Note: Wax treatment must be applied within 72 hours of final inspection and prior to loading. Excavators must be cleaned of dust, moisture, and debris before application.
5. Recommendation by Use Case
| Client Profile | Recommended Method | Rationale |
|---|---|---|
| Large Construction Firm (10+ units) | RO-RO | Cost-effective, fast turnaround, minimal handling |
| Mixed Equipment Exporter | Bulk Cargo | Efficient for consolidated shipments with other machinery |
| Remote Site Delivery (non-roadable unit) | Flat Rack | Accommodates disassembled booms or damaged units |
6. Compliance & Documentation
All export shipments must comply with:
– IMDG Code (for fuel and hydraulic fluid residues)
– China Customs Export Declaration (Form C)
– Bill of Lading (Sea Waybill or Telex Release)
– Certificate of Origin (China CO)
– Pre-Shipment Inspection (PSI) if required by destination country
7. Conclusion
For fleet managers and construction enterprises sourcing CAT 320 excavators from China, RO-RO shipping offers the optimal balance of cost, speed, and equipment integrity for roadable units. Flat Rack is essential for non-operational or modified configurations, while Bulk Cargo remains viable for mixed-load scenarios. Wax-based anti-corrosion treatment is non-negotiable to ensure long-term asset integrity upon arrival.
SEA LION International implements end-to-end logistics protocols aligned with ISO 39001 and IACS standards, ensuring compliance, traceability, and protection across all shipment types.
