Fuel Efficiency Performance

The CAT 320 GC small excavator, equipped with the Weichai WD615 engine, is engineered for optimal fuel efficiency in continuous-cycle operations. Under standard ISO 9249 test conditions and mixed load profiles (digging, swinging, loading), the machine achieves an average fuel consumption of 18.7 L/h (4.94 gal/h).

Advanced engine calibration and hydraulic pump modulation reduce idle fuel burn by up to 15% compared to previous-generation models. Real-world fleet data from 2025 field trials indicate fuel savings of 12–18% when operating in ECO mode with load-sensing hydraulics engaged.

For a typical 8-hour shift, projected fuel usage is 150 L (39.6 gal), making it a cost-effective solution for high-utilization construction environments.

---

Load Capacity & Structural Performance

The CAT 320 GC delivers robust load handling across diverse terrains and operational cycles:

• Maximum Digging Depth: 6,450 mm (21.16 ft)
• Reach at Ground Level: 9,850 mm (32.3 ft)
• Swing Torque: 42 kN·m (30,980 lb·ft)
• Drawbar Pull: 210 kN (47,200 lbf)

The HW19710 transmission ensures smooth gear shifts under load, maintaining tractive effort during uphill travel or heavy towing. The balanced axle load distribution (front: 55%, rear: 45% under standard operating weight) enhances stability during swing and lift operations.

Equipped with 12.00R20 radial tires, the machine supports high ground pressure tolerance (125 psi max) and extended service life in abrasive quarry and urban construction zones. These tires provide superior cut/chip resistance and heat dissipation, critical for 24/7 fleet operations.

---

Summary for Fleet Deployment

• Ideal for: Medium-scale excavation, pipeline work, foundation digging, and site preparation
• Fuel Efficiency Rating: ★★★★☆ (4.2/5 based on fleet telemetry)
• Maintenance Interval: 500-hour oil and filter service cycle; extended-life coolant (6,000-hour interval)
• Recommended Duty Cycle: High-intensity, multi-shift operations with scheduled downtime for inspections

This specification profile confirms the CAT 320 GC as a durable, fuel-efficient asset for construction fleets seeking reliability and low cost-per-hour performance in 2026 and beyond.

---

1. EXECUTIVE SUMMARY

This report details the manufacturing quality control protocols and Pre-Delivery Inspection (PDI) standards for the SEA LION SX-25 CAT Small Excavator (rated operating capacity: 2.5 metric tons). Specifications are validated against ISO 10979:2023 (Earth-Moving Machinery – Structural Integrity) and SAE J1090 (Durability Testing). Focus is placed on chassis structural resilience for extreme terrain operation and engine system longevity under sustained high-load conditions. Data confirms compliance with Tier 5 emissions standards while exceeding industry durability benchmarks by 18%.

4. PRE-DELIVERY INSPECTION (PDI) PROTOCOLS

All SX-25 units undergo a 127-point PDI at final assembly. Critical checks for fleet readiness:

4.1 Chassis & Undercarriage Verification

• Frame Alignment: Laser measurement of track frame parallelism (max. deviation: 1.5mm/m).
• Track Tension: Hydraulic pressure test at 35°C ambient (spec: 3.2–3.8 MPa).
• Swing Bearing Play: Dial indicator measurement (<0.3mm axial movement).

4.2 Powertrain & Hydraulic Validation

• Engine Burn-In: 72-hour continuous run at 85% load (data logged for torque curve analysis).
• Hydraulic Pressure Test: System held at 1.5x rated pressure (34.5 MPa) for 15 minutes.
• Leak Detection: Fluorescent dye test under UV light (all joints, hoses, cylinder seals).

4.3 Terrain-Specific Calibration

• Swing Brake Torque: Adjusted for 30° slope holding (min. 18 kN·m).
• Pilot Pressure Tuning: Optimized for low-grip surfaces (response time <0.3 sec).
• Counterweight Verification: Mass confirmed within ±0.5% of design spec.

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose excavators to chloride-laden air and condensation, accelerating corrosion on hydraulic cylinders, undercarriages, and electrical housings.

Recommended Anti-Corrosion Treatment:

• Method: Electrostatic wax spraying (oil-based, hydrophobic formulation)
• Application Points:
• Undercarriage (track links, rollers, idlers)
• Hydraulic cylinder rods
• Electrical connectors and battery terminals
• Exposed metal joints and pivot points
• Product Standard: Meets ISO 9227 (salt spray resistance), 500+ hours neutral salt fog test
• Thickness: 25–35 µm dry film
• Removal: Biodegradable citrus-based solvent post-delivery

Efficacy by Shipping Method:

Shipping Method	Wax Protection Necessity	Expected Corrosion Risk (Without Wax)
RO-RO	Critical	High (direct salt spray)
Bulk Cargo	High	High (humidity, condensation)
Flat Rack	Moderate to High	Medium (partial exposure)

Note: SEA LION International mandates wax spraying for all excavator exports, regardless of method. Field data from Q4 2025 shows a 76% reduction in post-arrival corrosion claims when wax treatment is applied.

---

4. Operational Recommendations

Priority	Recommendation
Cost-Sensitive Shipments	Use bulk cargo with mandatory wax spray and desiccant bags in operator cab. Monitor port crane safety records.
Time-Sensitive Deliveries	RO-RO preferred; ensure excavators are test-operated pre-loading to prevent immobilization on ramp.
High-Value or Precision Units	Flat Rack with full lashing plan (DNV-GL compliant), wax spray, and sealed cab. Ideal for units with factory-installed telematics.
Fleet Shipments (>10 units)	Mixed-mode strategy: RO-RO for standard models, Flat Rack for equipped variants.

---

5. Compliance & Documentation

All shipments must include:
– Bill of Lading (B/L) with “Machinery – Handle with Care” notation
– Packing List specifying weight, dimensions, and protective treatments
– Certificate of Conformity (CE, CCC, and local import codes)
– Wax Application Report (timestamped, photo-documented)

---

6. Conclusion

For CAT small excavator exports from China, RO-RO offers optimal balance of speed and cost for standard units, while Flat Rack provides superior protection for high-spec configurations. Bulk Cargo remains viable only under strict handling and protection protocols. Wax-based anti-corrosion spraying is non-negotiable across all methods to ensure equipment integrity upon arrival.

SEA LION International recommends integrating wax treatment into pre-shipment preparation SOPs and selecting shipping mode based on destination port capabilities, fleet value, and delivery timelines.
