Fuel Efficiency Analysis

Fuel consumption for the Weichai WD615-powered compact excavator is measured under ISO 9249 standard test conditions and real-world mixed-load operations. Average performance metrics are as follows:

• Idle Consumption: 3.2 L/h
• Medium Load (50% RPM): 14.5 L/h
• Full Load (Rated RPM, continuous dig cycle): 22.8 L/h

Under typical 8-hour shift operations (40% idle, 50% medium load, 10% full load), average fuel efficiency is approximately 14.2 L/100 operating hours, translating to ~19.7 L/h peak operational draw. The high-compression, direct-injection design of the WD615 engine ensures stable combustion and reduced particulate emissions, meeting China IV / Tier 3 equivalent standards.

Note: Units retrofitted with fuel optimization modules show up to 8% improvement in fuel economy under repetitive trenching cycles.

2. Cleaning & Degreasing – High-pressure wash of undercarriage and chassis.
3. Wax Spraying – Full anti-corrosion treatment per ASTM standards.
4. Moisture Absorption – Silica gel packs placed in cab and engine compartment.
5. Loading & Securing – Method-specific lashing and documentation.
6. In-transit Monitoring – GPS tracking and humidity logging (Flat Rack only).
7. Destination De-rigging – Wax residue removal, post-transit inspection.

---

Conclusion

For the export of used compact excavators from China, RO-RO offers the best balance of cost and efficiency for operational units, while Flat Rack containers provide superior protection for premium or long-distance shipments. Bulk Cargo is discouraged due to high damage and corrosion risks. Wax-based anti-corrosion treatment is non-negotiable and must be applied uniformly across all units, regardless of shipping method, to ensure equipment integrity upon arrival.

SEA LION International recommends integrating wax spraying into the pre-shipment protocol and selecting RO-RO or Flat Rack based on destination, volume, and equipment value.
