Fuel Efficiency Analysis

The Weichai WD615 engine is optimized for heavy-duty excavation and transport cycles, incorporating high-efficiency fuel injection and EGR (Exhaust Gas Recirculation) for compliance with Tier 4 Final emissions standards. Under mixed-load operating conditions (digging, traversing, and short-haul transport), the ride-on excavator achieves:

• Average Fuel Consumption: 28–32 L/100 km
• Fuel Efficiency Optimization: Achieved through HW19710 transmission’s wide gear spread, enabling engine operation within the optimal torque band (1,400–1,800 rpm) during load cycles
• Idle Fuel Savings: Integrated auto-idle shutdown (programmable at 3–5 minutes) reduces idle consumption by up to 18%

For fleet operations, this translates to ~12% improvement in fuel economy compared to legacy models using non-synchromesh transmissions and older engine platforms.

---

Load Capacity & Operational Performance

• Maximum Digging Depth: 7.2 meters (23.6 ft)
• Bucket Capacity (Standard): 1.8 m³ (2.35 yd³)
• Breakout Force (Bucket): 220 kN
• Lift Capacity (Over Front, 3m Radius): 6,800 kg (15,000 lbs)

The HW19710 transmission and tandem rear axle configuration enable stable load distribution during on-site repositioning and road transfer. The lift axle (loadable up to 10,000 kg when deployed) enhances maneuverability and reduces tire wear during non-load-bearing transit.

Axle load ratings are designed to meet regional weight-per-axle regulations (e.g., AASHTO in North America, EU Directive 96/53/EC), allowing legal road travel without special permits in standard configurations.

---

Summary

The ride-on excavator digger with Weichai WD615 engine and HW19710 transmission delivers high torque, reliable power transmission, and optimized fuel efficiency for continuous operation in quarry, civil infrastructure, and large-scale excavation projects. With a GVW of 31,000 kg and robust 12.00R20 radial tires, the unit supports heavy payloads while maintaining durability across abrasive terrains. Fleet managers can expect reduced TCO (Total Cost of Ownership) through extended service intervals (every 500 hours) and proven Weichai engine longevity exceeding 15,000 hours under proper maintenance.

4. Corrosion Protection: Wax Spraying Protocol

Marine environments expose excavator undercarriages, hydraulic cylinders, and structural steel to salt-laden air and condensation. To mitigate seawater-induced corrosion during transit:

4.1 Wax-Based Anti-Corrosion Treatment

• Product Type: Solvent-based, hydrophobic petroleum wax (e.g., Cosmoline-type or modern synthetic equivalents)
• Application Method: High-pressure spray (15–20 bar), targeting:
• Undercarriage frames
• Track links and rollers
• Hydraulic cylinder rods
• Unpainted weld zones
• Film Thickness: 50–75 µm (measured via wet film gauge)
• Drying Time: 4–6 hours (ambient 25°C, 60% RH)
• Protection Duration: Up to 6 months (ISO 9223 corrosivity category C3–C4)

4.2 Post-Treatment Procedures

• Venting: Allow engine bay and cab drainage points to remain unsealed
• Documentation: Apply corrosion protection certificate (ISO 12944-2 compliant) to shipping manifest
• De-waxing Guidance: Include solvent-based removal instructions in delivery package

SEA LION Recommendation: Wax spraying is mandatory for all sea-exported excavators, regardless of shipping method. RO-RO and Flat Rack units must be treated pre-loading.

---

5. Recommended Shipping Strategy

Scenario	Preferred Method	Rationale
Multiple operational units (>5 units)	RO-RO	Cost-effective, rapid loading, minimal handling damage
Oversized or non-functional units	Flat Rack + Wax Spray	Accommodates dimensions, enables full encapsulation
Budget-constrained, low-risk regions	Not advised – Bulk Cargo poses unacceptable corrosion and damage risk	—

---

6. Compliance & Certification

All shipments must comply with:
– IMDG Code (for fuel and hydraulic fluid residues)
– CTU Code (Cargo Transport Unit) for Flat Rack loading
– China Customs Export Declaration (CCED) – Machinery Classification 8429.52
– Bill of Lading (Sea Waybill) with corrosion protection endorsement

---

7. Conclusion

For reliable, industrial-grade export logistics of ride-on excavator diggers from China, RO-RO shipping with mandatory wax-based anti-corrosion treatment represents the optimal balance of cost, safety, and transit efficiency. Flat Rack containers are a viable alternative for non-standard units, provided securement and environmental protection protocols are strictly enforced. Bulk cargo shipping is not recommended due to high risk of mechanical and corrosion damage.

SEA LION International advises fleet managers and construction logistics planners to implement standardized pre-shipment wax spraying and to select RO-RO services via major Chinese ports (e.g., Shanghai, Guangzhou, Tianjin) with dedicated heavy equipment terminals.
