Subject: Executive Overview: XCMG XE750G Tractor Excavator Deployment in Target Markets

---

EXECUTIVE OVERVIEW

The XCMG XE750G Tractor Excavator (65-75 ton class) represents a critical asset for high-intensity material handling and earthmoving operations across mining, logistics terminal development, and large-scale infrastructure construction. Its design prioritizes operational resilience under extreme site conditions, directly addressing the core challenges faced by fleet managers in Africa, Russia, and Southeast Asia (SEA). Unlike conventional excavators, the XE750G integrates heavy-duty undercarriage geometry, reinforced structural joints, and a modular powertrain optimized for fuel efficiency with low-grade fuels—key factors driving its regional preference.

Regional Preference Drivers:
Africa: High ambient dust loads, variable fuel quality (ISO 8217:2017 RMG/RMK), and remote site logistics necessitate exceptional filtration (ISO 4406:18/16/13 compliance) and simplified maintenance access. The XE750G’s dual-stage air filtration and centralized lubrication points reduce unscheduled downtime by 22% in Sahel Basin mining operations (2025 field data).
Russia: Operation at -40°C requires specialized hydraulic fluid stability (ISO 11158 HVLP) and structural steel toughness (ASTM A572 Gr. 50). The model’s engine pre-heating system (integrated coolant/oil heaters) and cryogenic-grade seals ensure >95% cold-start reliability in Siberian logistics hubs, outperforming standard models by 37 operational hours/month.
Southeast Asia:* High humidity (80-95% RH), monsoon exposure, and corrosive saline environments demand advanced corrosion protection (ISO 12944 C5-M rating). The XE750G’s galvanized undercarriage and sealed electrical connectors reduce component failure rates by 31% in Vietnamese port expansion projects versus regional benchmarks.

Operational Advantage Summary:
The model’s dominance in these markets stems from validated performance under stress, not theoretical specs. SEA LION International’s 18-year export framework ensures consistent reliability through:
1. Pre-Deployment Refurbishment: All units undergo ISO 9001:2015-certified reconditioning, including hydraulic system flushing (NAS 1638 Class 5), structural weld inspection (AWS D1.1), and engine rebuilds using XCMG OEM parts.
2. Parts Availability: 98.7% spare parts fill rate within 14 days globally via SEA LION’s bonded logistics hubs (Johannesburg, Vladivostok, Singapore), mitigating supply chain volatility.
3. Logistics Optimization: RO-RO vessel deployment for complete units (reducing onsite reassembly time by 65%) or containerized critical components for remote sites.

Key Performance Metrics vs. Regional Competitors (2025 Field Data)

Parameter	XE750G (SEA LION Refurb)	Regional Competitor Avg.	Advantage
Mean Time Between Failures (hrs)	1,150	820	+40.2%
Fuel Consumption (L/hr @ 70% load)	42.7	48.9	-12.7%
Maintenance Interval (hrs)	500	350	+42.9%
Corrosion-Related Downtime	1.8%	6.2%	-71.0%

---

CONCLUSION

For fleet managers operating in Africa, Russia, or SEA, the XCMG XE750G—delivered via SEA LION’s certified refurbishment and logistics ecosystem—provides quantifiable reductions in total cost of ownership (TCO) through extended service life, lower fuel consumption, and minimized weather-related downtime. Its engineering alignment with regional environmental extremes, coupled with SEA LION’s commitment to parts transparency and technical support, establishes it as the preferred operational backbone for mission-critical earthmoving. Long-term partnership models, including performance-based maintenance contracts, further de-risk fleet deployment in volatile markets.

Fuel Efficiency Analysis

The Weichai WD615 engine is optimized for high-torque, low-RPM operation typical in excavation and haul cycles. Under mixed operational profiles (digging, loading, and short-haul transport), the tractor excavator achieves:

• Average Fuel Consumption: 28–32 L/100 km (loaded cycle)
• Idle Optimization: Engine auto-idle and shutdown reduce idle fuel burn by up to 18%
• Eco Mode Performance: In economy transmission mode (HW19710), fuel efficiency improves by 6–9% with minimal impact on cycle time

Fuel efficiency is further enhanced by:
– High-efficiency Bosch high-pressure common rail injection
– Integrated engine-transmission calibration for optimal gear utilization
– Low rolling resistance 12.00R20 radial tires

Note: Real-world performance may vary based on terrain, load distribution, and operator technique.

The front axle is designed with load-sensing suspension to handle dynamic digging forces, while the rear tandem axles include load-balancing beams to prevent overloading under uneven terrain.

---

Conclusion

The tractor excavator equipped with the Weichai WD615 engine, HW19710 transmission, and 12.00R20 tire package delivers a balanced solution for construction fleets requiring high productivity, fuel economy, and durability. With a GVW of 30,000 kg and optimized axle loading, it supports both excavation and short-haul tasks without requiring additional transport logistics. Fleet managers can expect reduced TCO (Total Cost of Ownership) through extended service intervals (1,000-hour oil change cycle) and proven Weichai engine reliability in harsh environments.

---

4. Method-Specific Analysis

4.1 RO-RO Shipping

• Advantages:
• Minimal handling reduces mechanical stress.
• Fast port turnaround; no cranes required for loading/unloading.
• Standardized lashing protocols per CTU Code.
• Limitations:
• Limited to ports with RO-RO facilities.
• Higher exposure to salt spray on open decks.
• Recommendation: Preferred for serial exports to Europe, Middle East, and Africa.

4.2 Bulk Cargo

• Advantages:
• Lower base cost for non-containerized freight.
• Accommodates irregular dimensions.
• Limitations:
• High risk of impact damage during loading.
• No environmental protection; direct seawater contact likely.
• Extended port dwell times.
• Recommendation: Not advised for high-value excavators unless cost is paramount and insurance coverage is comprehensive.

4.3 Flat Rack (FR) Containers

• Advantages:
• Full structural support; suitable for wide/long units.
• Stackable and ISO-compliant.
• Can be covered with tarpaulins (partial weather protection).
• Limitations:
• Requires specialized lifting equipment.
• Exposed sides increase corrosion risk.
• Higher freight surcharge due to non-standard dimensions.
• Recommendation: Optimal for oversized models or combined shipments with other heavy machinery.

5. Corrosion Protection: Wax Spraying Protocol

Tractor excavators are highly susceptible to salt-induced corrosion during marine transit, particularly in coastal and tropical zones. SEA LION International recommends the application of temporary anti-corrosion wax spray as a mandatory pre-shipment procedure.

5.1 Application Specifications

Parameter	Requirement
Wax Type	Solvent-based, hydrophobic polymer coating (e.g., Dinitrol AVA 25, Cosmoline C5)
Coverage Areas	Undercarriage, track links, hydraulic cylinders, exposed fasteners, cab underbody
Film Thickness	25–50 microns (uniform coat)
Drying Time	2–4 hours (20°C, 50% RH)
Removal Method	Biodegradable solvent wash or steam cleaning upon delivery
Shelf Life (in transit)	Up to 6 months in marine conditions

5.2 Benefits

• Forms a moisture-resistant barrier on ferrous components.
• Self-healing properties resist minor abrasion during handling.
• Non-toxic and compliant with IMO MARPOL Annex III.
• Reduces post-arrival reconditioning labor by up to 70%.

---

6. Recommended Export Protocol

1. Pre-shipment Preparation:
2. Drain hydraulic and cooling systems.
3. Secure boom and bucket in transport position.

4. Apply wax spray to all corrosion-prone zones.

5. Shipping Method Selection:

6. Standard Units: RO-RO (primary), Flat Rack (secondary).
7. Oversized/Custom Models: Flat Rack with tarpaulin cover.

8. Avoid: Bulk cargo unless no alternative exists.

9. In-Transit Monitoring:

10. Use IoT humidity/tilt sensors in container/vessel hold.

11. Track vessel route for exposure to high-salinity zones.

12. Post-Arrival:

13. Inspect for lashing integrity and coating condition.
14. Perform wax removal and functional check before deployment.

---

7. Conclusion

For the export of tractor excavators from China, RO-RO shipping offers the optimal balance of cost, safety, and efficiency for standard models. Flat Rack containers provide flexibility for non-standard units, while bulk cargo is discouraged due to high damage and corrosion risk. The consistent application of industrial wax spraying is critical to preserving equipment integrity across all methods. SEA LION International endorses RO-RO with wax protection as the benchmark for 2026 export operations.
