• Average Fuel Consumption: 28–32 L/h under typical excavation and loading cycles.
• Fuel Efficiency Improvement: ~12% over prior-generation models due to intelligent load-sensing hydraulics and engine ECU tuning.
• Idle Fuel Savings: Auto-idle shutdown (configurable at 3–5 minutes) reduces idle consumption by up to 18% over an 8-hour shift.

Field data from 2025 pilot fleets indicates an average of 2.1 m³ of material moved per liter of diesel in mixed soil conditions (clay, loam, gravel), making it one of the most fuel-efficient models in its class.

---

Load Capacity & Structural Performance

The Power Wheels Excavator is engineered for maximum payload and durability in quarry, infrastructure, and large-scale civil projects.

• Bucket Capacity (Standard): 1.8 m³ (can be upgraded to 2.4 m³ for bulk material handling).

Corrosion Protection: Wax Spraying Technology

Overview

Power Wheels Excavators are vulnerable to galvanic and surface corrosion during extended sea voyages due to exposure to saltwater aerosols and high humidity. SEA LION International recommends anti-corrosion wax spraying as a standard protective measure.

Application Protocol

• Pre-Treatment: Degrease and dry all metallic surfaces
• Spray Type: Solvent-based, hydrophobic synthetic wax (e.g., DINITROL 4600L)
• Coverage Areas:
• Undercarriage and track links
• Hydraulic cylinder rods
• Electrical connectors (non-conductive variant)
• Frame weld joints and fasteners
• Thickness: 25–35 µm dry film
• Curing: 24 hours at 20°C prior to shipping

Benefits

• Forms moisture barrier resistant to salt spray (ASTM B117 compliant)
• Reduces maintenance downtime post-delivery by up to 60%
• Compatible with rubber and plastic components
• Removable via industrial degreaser upon arrival

Recommendation: Wax application mandatory for all units shipped via RO-RO and Bulk Cargo; optional but advised for Flat Rack.

Risk Assessment Matrix

Risk Factor	RO-RO	Bulk Cargo	Flat Rack
Saltwater Corrosion	High	Very High	Medium
Physical Impact Damage	Medium	High	Low
Moisture Ingress	Medium	High	Low
Theft/Vandalism	Medium	High	Low
Delayed Customs Clearance	Low	Medium	Low

---

Recommendations

1. For High-Volume Fleets (≥50 units/shipment):
2. Preferred Method: RO-RO with wax spraying

3. Rationale: Faster turnaround, reduced handling, scalable operations

4. For Budget-Constrained Projects:

5. Preferred Method: Bulk Cargo only if wax spraying and desiccant sealing applied

6. Risk Mitigation: Include post-arrival inspection and re-lubrication clause in contract

7. For Premium or Demo-Fleet Deliveries:

8. Preferred Method: Flat Rack container
9. Rationale: Maximum protection, traceability, and branding presentation

---

Conclusion

While RO-RO offers operational efficiency for serial exports, Flat Rack provides superior asset protection for corrosion-sensitive equipment. Bulk Cargo remains a cost-effective option only when paired with rigorous anti-corrosion protocols. Wax spraying is non-negotiable for long-haul maritime export from China’s coastal ports. SEA LION International advises integrating wax protection into OEM pre-shipment standards to ensure fleet readiness upon arrival.
