• Average Fuel Consumption: 28–32 L/h under full-load digging cycles
• Eco-Mode Operation: Reduces fuel use by 12–15% during light-to-moderate duty
• Idle Management System: Auto-shutdown and RPM governor reduce idle fuel burn by up to 20%
• Fuel Efficiency Benchmark: 1.8–2.1 L per bank cubic meter (BCM) moved, depending on soil density and cycle time

This configuration supports a 30% improvement in fuel economy over legacy models using non-optimized transmissions and older engine calibrations.

---

4. Load Capacity & Structural Integrity

The HDE-8000R is structured for high dynamic loading and repetitive stress conditions:

• Maximum Digging Depth: 7,200 mm
• Bucket Capacity (HE): 3.8–4.5 m³ (adjustable based on material density)
• Swing Torque: 85 kN·m (hydraulic)
• Counterweight Mass: 8,200 kg (standard configuration)

Axle load distribution is engineered to maintain compliance with road transport regulations (when permitted) while maximizing traction and stability during operation. The rear-biased load (60/40 rear/front) ensures optimal push force during trenching and grading.

Tires (12.00R20) are rated for continuous operation at 5 km/h under full payload, with reinforced sidewalls to resist cuts and impacts in rocky terrain. Load capacity per tire (dual setup) reaches 5,450 kg, supporting the rated gross machine weight of 36.3 metric tons.

---

5. Operational Recommendations

• Transmission Use: Utilize low-range gears in high-resistance digging; shift to high-range for travel between zones
• Tire Maintenance: Monitor inflation at 8.5 bar (123 psi); underinflation reduces load capacity by up to 30%
• Engine Service Interval: 500-hour oil change with Weichai-approved CF-4 15W-40 lubricant
• Axle Load Monitoring: Conduct monthly axle load checks to prevent overloading and premature wear

---

6. Conclusion

The R/C Excavator HDE-8000R delivers industrial-grade performance with a balanced emphasis on fuel economy, durability, and payload efficiency. Its integration of the Weichai WD615 engine and HW19710 transmission ensures reliable power delivery, while axle and tire specifications support heavy-duty deployment across demanding terrains. Recommended for fleet operations requiring >90% availability and low cost-per-cubic-meter excavation.

1. Executive Summary

This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack shipping—for the export of remote-controlled (R/C) excavators from manufacturing hubs in China to global construction markets. Key criteria include cost-efficiency, equipment protection, transit time, and corrosion mitigation. A standardized wax-based anti-corrosion treatment is recommended for all shipment types to ensure integrity during ocean transit.

---

2. Equipment Profile: R/C Excavators

---

3. Comparative Shipping Methods

Criteria	RO-RO Shipping	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or towed	Crane-lifted into hold	Secured on open-top frame
Cargo Protection	Moderate (exposed decks)	Low (shared hold space)	High (custom lashings)
Weather Exposure	High (partial cover)	Medium (interior hold)	High (open structure)
Transit Time (Asia → EU)	28–35 days	35–45 days	30–40 days

Suitability for R/C Units	Moderate	Low	High

---

4. Corrosion Protection: Wax Spraying Treatment

Salt-laden marine environments pose a severe risk to excavator undercarriages, hydraulic joints, and electrical housings. SEA LION International mandates the following anti-corrosion protocol for all export shipments:

4.1 Wax-Based Corrosion Inhibitor (C.I. Grade X7W)

• Composition: Solvent-free microcrystalline wax with volatile corrosion inhibitors (VCI)
• Application Method: High-pressure spray (12–15 bar), full undercarriage + joint coverage
• Thickness: 50–75 µm dry film
• Performance:
• Salt spray resistance: >1,000 hours (ASTM B117)
• Hydrophobic barrier: Prevents seawater adhesion
• Non-conductive: Safe for proximity to ECUs

4.2 Application Workflow

1. Pre-treatment: Clean and dry all metal surfaces
2. Mask sensitive sensors and exhaust ports
3. Apply wax spray in controlled environment (15–25°C)
4. Cure time: 4 hours minimum before loading
5. Post-transit removal: Biodegradable citrus-based solvent

Note: Wax treatment is non-negotiable for all shipping modes and reduces post-arrival rework by up to 70%.

---

5. Recommendation by Use Case

Customer Profile	Recommended Method	Rationale
High-volume fleet (10+ units)	RO-RO	Fast turnaround, lower handling cost, compatible with serial dispatch
Budget-focused project sites	Bulk Cargo (with wax)	Lowest cost; acceptable only with full wax protection and insurance
High-value or precision units	Flat Rack	Maximum control over securing, ideal for oversized or non-standard R/C models

---

6. Compliance & Documentation

All shipments must adhere to:
– IMDG Code (for residual fuel/hydraulic fluid)
– CSS Code (Cargo Securing Manual compliant lashing)
– CIQ Export Clearance (China Inspection & Quarantine)
– Bill of Lading with “Heavy Machinery” endorsement

---

7. Conclusion

For optimal balance of cost, protection, and delivery speed, Flat Rack shipping with wax corrosion treatment is the preferred solution for high-integrity R/C excavator exports. RO-RO remains viable for rapid deployment of standard models, while Bulk Cargo is conditionally acceptable only under stringent protective protocols. SEA LION International enforces wax spraying as a baseline standard across all modalities to ensure equipment readiness upon arrival.
