---

Fuel Efficiency Analysis

The Weichai WD615 engine, integrated with intelligent load-sensing hydraulic systems and an optimized HW19710 transmission, delivers a fuel efficiency of 18.5–22.0 L/h (4.9–5.8 US gal/h) under standard digging cycles. At 60% load factor (typical for mixed fleet operations), the machine averages 20.3 L/h. This represents a 12% improvement over previous-generation models due to:

• Variable-Speed Fan Drive reducing parasitic losses
• Auto-Idle & Engine Power Modes (Eco/Heavy/Boost)
• Regenerative Circuitry in swing and boom functions

Fuel consumption per cubic meter moved is approximately 6.7 L/m³ in cohesive soil under optimal conditions, making this model competitive in high-utilization scenarios.

---

Load Capacity & Structural Performance

The XE370G-class excavator is engineered for maximum breakout force and dump height, critical for loading articulated dump trucks (ADTs) and processing stockpiles.

Load Parameter	Value
Max Digging Depth	7,220 mm (23.7 ft)
Max Reach at Ground	10,150 mm (33.3 ft)
Max Dump Height	6,890 mm (22.6 ft)
Boom Lifting Capacity (at 6m radius)	6,200 kg (13,668 lbs)
Counterweight Clearance (Tail Swing)	2,980 mm (9.8 ft)

The HW19710 transmission provides robust torque transfer (max input torque: 1,970 N·m) with minimal slippage, supporting rapid repositioning on job sites. Coupled with high-flow hydraulic options (up to 230 L/min), the system enables use of heavy-duty attachments such as hydraulic hammers and multi-processors.

Axle loads are balanced to comply with on-road transport regulations when equipped with transport undercarriage (optional). The 12.00R20 tires offer high cut-and-abrasion resistance, with a rated load index of 2,650 kg per tire at 5 bar (72.5 psi), suitable for mixed terrain including crushed rock and wet clay.

---

Operational Recommendations

• Fleet Integration: Ideal for quarries, large civil projects, and heavy demolition due to high payload and durability.
• Maintenance Interval: Engine oil and filter changes every 500 hours; transmission fluid every 1,000 hours.
• Cold Climate Suitability: WD615 supports -25°C operation with appropriate coolant and fuel conditioning.

This specification set ensures maximum uptime, reduced cost-per-ton, and compatibility with standard support equipment across industrial environments.

Corrosion Protection Protocol: Wax Spraying System

Marine transit exposes heavy equipment to salt-laden air and condensation, accelerating corrosion on hydraulic cylinders, pivot joints, and undercarriage components. SEA LION International mandates the following anti-corrosion standard for all exported Bobcat excavators:

Wax-Based Protective Coating (Industrial Grade)

Parameter	Specification
Coating Type	Solvent-based hydrophobic wax emulsion
Application Method	High-pressure spray + brush detailing
Coverage Areas	Undercarriage, boom/linkage joints, radiator fins, battery tray, control valves
Thickness (Dry Film)	50–75 µm
Salt Spray Resistance	>1,000 hours (ASTM B117 compliant)
Service Life (Transit)	Up to 90 days
Removal Process	Biodegradable degreaser; no residue
OEM Compliance	Compatible with Bobcat paint and seals

Implementation Workflow:
1. Pre-treatment: Degrease and dry all surfaces.
2. Apply wax via automated spray booth at final staging yard (China).
3. Seal operator cabin vents and exhaust ports.
4. Document coating application in export compliance dossier.

Advantage: Wax layer self-heals minor scratches and remains effective in high-humidity holds or open decks.

---

Recommendations

Scenario	Recommended Method	Rationale
High-volume fleet deployment (≥10 units)	RO-RO	Fast turnaround, low damage risk, efficient roll-off at destination
Budget-constrained single unit	Bulk Cargo	Lowest freight cost; acceptable if corrosion protection is reinforced
Oversized configuration or non-standard load	Flat Rack	Accommodates width/height; secure lashing; ideal for inland port delivery
High-corrosion-risk routes (e.g., tropical)	RO-RO + Wax Spray	Enclosed transport + chemical barrier maximizes asset longevity

---

Conclusion

For the export of the largest Bobcat excavator models from China, RO-RO shipping combined with industrial wax spraying provides the optimal balance of protection, speed, and fleet scalability. While Bulk Cargo offers short-term cost savings, long-term maintenance costs due to corrosion may offset initial gains. Flat Rack remains a viable alternative for non-RO-RO-serviced ports, provided weatherproofing and lashing standards are rigorously enforced.

SEA LION International recommends integrating wax-based corrosion inhibition into all export workflows, regardless of shipping mode, to ensure equipment arrives in commission-ready condition.
