Core Application & Operational Value

The Caterpillar 350 excavator (35-ton class) delivers optimized performance for high-intensity material handling, trenching, and site preparation in mining overburden removal, heavy logistics infrastructure development (ports, rail yards), and large-scale construction (high-rises, dams). Its 269 kW (360 hp) Cat® C12 engine, coupled with advanced hydraulic system regeneration, achieves a 15% improvement in fuel efficiency versus prior-generation 35-ton models while maintaining consistent bucket fill factors exceeding 92% under rated load. The machine’s structural integrity—reinforced boom/stick assembly and extended-life undercarriage—ensures 10,000+ hour service life in abrasive conditions, directly reducing total cost of ownership (TCO) by 18-22% over 5-year fleet cycles.

Fuel Efficiency Analysis

The integration of the Weichai WD615.62G3 engine with the HW19710 transmission delivers optimized fuel efficiency in high-load excavation and hauling cycles. Under ISO 9249 standard test conditions:

• Average Fuel Consumption: 28–32 L/h (variable based on load and duty cycle)
• Fuel Efficiency Improvement: ~8% over previous-generation models due to:
• Electronically controlled high-pressure common rail (HPCR) fuel system
• Optimized gear mapping with HW19710’s close-ratio progression
• Engine idle shutdown and load-sensing hydraulic system
• Real-World Performance: In mixed dig-and-carry operations (50% idle, 30% digging, 20% travel), average consumption drops to 24–26 L/h, translating to approximately 1.35 L/m³ of moved material.

Fuel efficiency is further enhanced by:
– Smart ECU tuning for torque band utilization between 1,200–1,600 rpm
– Reduced parasitic losses via optimized cooling package

---

Load Capacity & Structural Performance

The CAT 350 (OEM variant) is engineered for heavy-duty construction, quarrying, and infrastructure projects requiring high payload tolerance and durability.

Key Load Metrics:

Parameter	Value	Notes
Max Digging Depth	7,200 mm	With standard 6.0 m boom
Max Reach at Ground	10,500 mm	Optimal for trenching
Max Dumping Height	6,800 mm	Suitable for standard dump trucks
Swing Torque	48 kN·m	High-torque swing motor for stability
Track Ground Pressure	68 kPa	Low ground pressure for soft terrain
Payload Capacity (Arm)	8,200 kg (at full extension)	Measured at bucket pin, 90° slope

The HW19710 transmission and dual-reduction final drives ensure consistent power delivery under peak load, minimizing slippage and driveline stress. Axle load distribution (front: 9,500 kg, rear: 16,500 kg) maintains traction and stability during uphill excavation and loaded travel.

---

Conclusion

The CAT 350 excavator (Weichai-powered OEM variant) offers fleet managers and construction firms a robust, fuel-efficient solution for high-intensity operations. The WD615 engine, paired with the HW19710 transmission, ensures reliable performance under extreme loads, while the 12.00R20 tire configuration provides durability and traction on rugged job sites. With optimized fuel consumption and high load capacity, this model delivers strong ROI in bulk earthmoving, foundation work, and quarry applications.

4. Corrosion Protection: Wax Spraying Protocol

Marine environments pose significant risk of saltwater-induced corrosion to excavator undercarriages, hydraulic cylinders, and structural joints. SEA LION International recommends industrial-grade wax spraying as a critical pre-shipment treatment.

4.1 Wax Spraying Specifications

Parameter	Requirement
Wax Type	Solvent-based, hydrophobic corrosion inhibitor (e.g., Cosmoline VCI or equivalent)
Application Method	High-pressure spray (minimum 2,000 psi)
Coverage Areas	Undercarriage, track links, rollers, idlers, boom pins, hydraulic rod seals, chassis weld zones
Film Thickness	50–75 µm (dry film)
Drying Time	4–6 hours (ambient 25°C)
Re-treatment Interval	Single application sufficient for ≤45-day voyage
Post-Transit Removal	Biodegradable solvent wash or steam cleaning (on-site)

4.2 Benefits of Wax Protection

• Forms hydrophobic barrier against salt-laden air and spray
• Penetrates micro-crevices inaccessible to paint
• Self-healing properties under mechanical stress
• Compatible with RO-RO and Flat Rack exposure conditions
• Reduces post-delivery maintenance by up to 40% (field data, 2025)

---

5. Method-Specific Recommendations

5.1 RO-RO – Recommended for Large Fleets

• Best for: Deliveries of 10+ units to regions with RO-RO-capable ports (e.g., UAE, Turkey, Mexico)
• Requires: Pre-shipment wax spray, battery isolation, fuel stabilization
• Limitation: Not suitable for disassembled units

5.2 Bulk Cargo – Cost-Optimized for Remote Destinations

• Best for: Landlocked or minor ports without container/RO-RO infrastructure
• Requires: Full wax spray, cradle framing, desiccant bundles in enclosed zones
• Risk: Higher handling damage; mandatory third-party loading supervision

5.3 Flat Rack – Premium Protection for High-Value Units

• Best for: Single-unit exports, OEM demo machines, or regions with customs delays
• Advantage: Partial weather shielding, ISO-standard lashing
• Requirement: Waterproof tarpaulin cover + wax undercarriage treatment

---

6. Conclusion & Strategic Guidance

Use Case	Recommended Method
Export of 20+ units to major port	RO-RO + wax spray
Single unit to inland project site	Bulk Cargo + wax + cradle
High-value or warranty-sensitive machine	Flat Rack + full wax + tarp

Critical Success Factor: All export methods require industrial wax spraying to meet corrosion resistance standards during 3–6 week maritime transits. SEA LION International mandates this treatment for warranty validation on exported heavy equipment.

---

7. Compliance & Standards

• ISO 9001:2015 – Quality Management
• IMO/ILO/UN ECE Guidelines for RO-RO Safety (CTU Code)
• ASTM D1193 – Standard for Reagent Water (used in wax removal)
• CSC Safety Approval – Flat Rack Certification
