Fuel Efficiency Analysis

The Weichai WD615 engine, integrated with the HW19710 transmission, utilizes high-pressure common rail (HPCR) fuel injection and electronically controlled governor logic to optimize combustion efficiency. Under ISO 8178-C1 test cycles:

• Average Fuel Consumption:
• 28–32 L/100 km (loaded haul, mixed terrain)

• 18–22 L/100 km (light-duty cycle, urban grading)

• Idle Fuel Burn: 3.8 L/h (equipped with auto-idle shutdown at 5 min)

• Econ Mode Reduction: Up to 12% fuel savings during non-peak load operations via torque mapping adjustment.

The powertrain’s gear-split strategy in the HW19710 allows for precise engine load matching, reducing lugging and over-revving—critical for maintaining fuel economy in stop-start excavation and short-haul dump cycles.

---

Load Capacity & Operational Performance

The CAT 310-class platform with reinforced frame and upgraded suspension delivers high payload tolerance:

• Maximum Payload Capacity: 14,500 kg (on improved surfaces, 60/40 front/rear balance recommended)
• Drawbar Pull: 225 kN (1st gear, max traction)
• Gradeability: 35% continuous, 48% short-term (wet clay, gravel)
• Bucket Breakout Force: 132 kN (standard 0.6 m³ bucket)

Axle load distribution is optimized for compliance with national bridge formula regulations (e.g., China GB1589-2016). The 6×6 configuration ensures even weight dispersion, minimizing ground pressure (average: 0.68 MPa) and reducing surface damage on sensitive job sites.

Tires (12.00R20) are rated for 129 load index (1,360 kg/tire) and operate optimally at 850 kPa inflation pressure. Reinforced sidewalls and deep tread (22/32″) provide extended service life in rocky or abrasive conditions.

Corrosion Mitigation: Wax Spraying Protocol

Seawater exposure during maritime transit presents a critical risk to excavator undercarriages, hydraulic fittings, and electrical junctions. SEA LION International mandates the following protective treatment prior to shipment:

Wax Spraying Protection System (WSPS-2026)

Component	Application Method	Coverage Target	Protection Duration
Undercarriage	High-pressure spray (250 bar)	Tracks, rollers, idlers, frame rails	Up to 12 weeks
Hydraulic Cylinders	Brush-assisted mist coating	Rods, gland areas	8–10 weeks
Electrical Enclosures	Precision nozzle (non-conductive)	Connectors, fuse boxes	6 weeks
Engine Compartment	Fogging + targeted brush	Radiator fins, alternator, mounts	10 weeks
Coating Type	Solvent-based synthetic micro-wax (ZnCa-inhibited)	MIL-STD-1246D compliant	Salt fog tested (ASTM B117)

Post-Transit De-waxing: Required before commissioning. Use biodegradable degreaser (e.g., D-85X) and high-pressure freshwater rinse.

---

Recommendation Matrix

Use Case	Recommended Method	Rationale
High-volume fleet export (Africa, SE Asia)	RO-RO + Wax Spray	Fast turnaround, cost-effective with enhanced protection
Budget-sensitive, short-distance export	Bulk Cargo + Full Wax	Lowest cost; wax offsets high corrosion risk
High-value, long-haul (South America, EU)	Flat Rack + Wax + Tarp	Maximum control, optimal protection, traceability
Harsh marine environments (e.g., Pacific)	Flat Rack + Double Wax	Extended exposure protection; redundancy

---

Compliance & Documentation

All shipments must include:
– Packing List (declared weight, dimensions)
– Bill of Lading (clean, on-board)
– Certificate of Origin (China CO)
– Pre-Shipment Inspection (PSI) Report
– Wax Application Certificate (with batch # and coverage log)

---

Conclusion

For CAT 310 excavator exports from China, Flat Rack with wax spraying offers the highest integrity for long-distance and high-value deployments. RO-RO remains optimal for rapid deployment in stable maritime zones, provided wax protection is uniformly applied. Bulk Cargo is discouraged unless cost is the overriding factor and post-arrival refurbishment is budgeted.

SEA LION International recommends integrating wax spraying as a non-negotiable step across all modal choices to ensure equipment readiness upon arrival.
