Fuel Efficiency Analysis
The Weichai WD615 engine is calibrated for optimal combustion efficiency under variable load conditions. Integrated with a high-efficiency hydraulic system and smart power management, the CASE 320 GC achieves an average fuel consumption of:
- 18.5 L/h under heavy digging cycles (90–100% load)
- 13.2 L/h during moderate swing-and-travel operations
- 9.8 L/h in idle or low-demand scenarios
This represents a 12–15% improvement in fuel economy over previous-generation models, attributed to:
– Electronic Unit Pump (EUP) fuel injection
– Adaptive engine speed control (Auto-idle & Power Boost Mode)
– Reduced parasitic losses via optimized hydraulic circuit design
For a typical 8-hour shift in mixed-duty applications, total fuel usage averages 115–130 L, enhancing cost predictability for fleet operations.
Load Capacity & Structural Performance
The CASE 320 GC is engineered for high-cycle loading in quarry, trenching, and foundation work. Key load-bearing features include:
- Reinforced Undercarriage: Heavy-duty track frames with box-section side members
- Axle Rating: HW19710 transmission paired with Dana OER2000 axles (front and rear), rated for continuous 28-ton GVW
- Tire Performance: 12.00R20 tires with 3,600 kg per tire load rating (ISO 4250-1), 16-ply equivalent, designed for off-road durability and cut resistance
- Drawbar Pull: 220 kN maximum, enabling effective operation on 30° inclines with full load
The excavator maintains stability and traction under full bucket load (up to 1.8 m³ of dense material) due to balanced weight distribution and low center of gravity.
Operational Recommendations
- Maintenance Interval: 500-hour oil and filter changes (Weichai-recommended)
- Transmission Service: HW19710 requires GL-5 85W-90 gear oil; inspection every 1,000 hours
- Tire Monitoring: Regular tread depth and pressure checks (recommended: 5.5 bar / 80 psi) to prevent premature wear
Conclusion
The CASE 320 GC excavator, equipped with the Weichai WD615 engine and HW19710 transmission, delivers industrial-grade performance with measurable improvements in fuel efficiency and load-handling capability. Its compatibility with 12.00R20 radial tires ensures reliable ground contact across rough terrains, making it a cost-effective solution for construction fleets requiring durability and operational consistency.
This model is recommended for high-utilization environments where uptime, fuel economy, and structural resilience are mission-critical.

Shipping & Logistics Solutions

Industrial Specification Report 2026
Prepared by: SEA LION International – Senior Engineering Division
Subject: Logistics Solutions for Exporting Case Excavators from China
Target Audience: Fleet Managers & Construction Equipment Procurement Teams
Executive Summary
This report evaluates three primary maritime logistics methods for exporting case excavators from manufacturing hubs in China (e.g., Qingdao, Shanghai, Xiamen) to global project sites: RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping. Each method is assessed for suitability, cost-efficiency, equipment protection, and operational integration. A standardized wax-based anti-corrosion treatment is recommended for all export units to mitigate seawater exposure during transit.
1. Equipment Profile: Case Excavator (Typical Export Unit)
| Parameter | Specification |
|---|---|
| Model Class | 15–35 Ton Crawler Excavator |
| Dimensions (L×W×H) | 9.8 m × 3.0 m × 3.2 m |
| Operating Weight | 18,500–32,000 kg |
| Undercarriage Type | Steel Track, Hydraulic Swing |
| Export Condition | New, Factory-Tested, CE/ISO Compliant |
| Special Handling Required | Yes (Corrosion Protection, Securing) |
2. Comparative Shipping Methods
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo Shipping | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Crane-lifted into open hold | Crane-lifted onto open-top frame |
| Securing Method | Wheel chocks, lashing points | Wooden cradles, steel strapping | Twist locks, lashing bridges |
| Vessel Type | Dedicated RO-RO carrier | Gearless or geared bulk carrier | Container vessel (specialized) |
| Transit Time (Shanghai → Rotterdam) | 28–35 days | 35–45 days | 30–40 days |
| Port Infrastructure | Requires RO-RO ramp facility | Requires heavy-lift crane | Requires container terminal |
| Cost (USD/unit) | $2,200–$2,800 | $1,900–$2,400 | $3,100–$3,800 |
| Risk of Damage | Low (minimal handling) | Medium (rigging stress) | Low–Medium (exposure to elements) |
| Weather Exposure | Low (enclosed decks) | Medium (partially covered holds) | High (open-top, no cover) |
| Insurance Premium | Lower | Moderate | Higher |
| Best For | High-volume fleets, operational units | Budget-sensitive, inland delivery | Oversized units, non-operational |
3. Corrosion Protection: Wax Spraying Treatment
Marine environments expose excavator undercarriages, hydraulic components, and metal joints to salt-laden air and condensation. To ensure operational integrity upon delivery, SEA LION International mandates the following protective protocol:
Wax-Based Anti-Corrosion System (Specification: ASTM D130 / ISO 9227)
| Component Protected | Treatment Method | Coating Thickness | Duration of Protection |
|---|---|---|---|
| Undercarriage (Tracks, Rollers) | High-pressure wax spray (petroleum-based, pH-neutral) | 25–35 µm | Up to 120 days |
| Hydraulic Cylinders & Pins | Brush-on wax sealant + vapor phase inhibitor (VCI) wrap | 15–20 µm | 90 days |
| Engine Compartment | Fogging with corrosion-inhibiting wax emulsion | 10–15 µm | 60 days |
| External Steel Surfaces | Electrostatic wax coating (oven-cured) | 30–40 µm | 120+ days |
Application Process:
1. Pre-treatment: Degrease and dry all surfaces.
2. Automated spray booth application at Chinese OEM facility.
3. Post-application inspection (adhesion, coverage).
4. Documentation: Certificate of Protection (CoP) issued per unit.
4. Method Recommendation Matrix
| Use Case | Recommended Method | Rationale |
|---|---|---|
| Export of 10+ operational units to EU | RO-RO | Fast turnaround, low handling risk, ideal for running gear |
| Single unit to remote inland site (e.g., Kazakhstan) | Bulk Cargo | Cost-effective; integrates with rail/truck transshipment |
| Excavator with attachments (breaker, auger) | Flat Rack | Accommodates extended dimensions; secure lash points |
| Projects with strict delivery timelines | RO-RO | Shortest transit; predictable scheduling |
| High-humidity destination ports (e.g., Southeast Asia) | RO-RO or Flat Rack (with full wax + shrink wrap) | Minimize salt exposure during port layover |
5. Compliance & Documentation
All export shipments must include:
– Bill of Lading (B/L)
– Certificate of Origin (China CO)
– Packing List (with serial numbers)
– Certificate of Corrosion Protection (CoP)
– CE/ISO Compliance Declaration
– Fumigation Certificate (if wooden dunnage used)
6. Conclusion
For fleet managers and construction firms sourcing case excavators from China, RO-RO shipping offers the optimal balance of speed, safety, and cost for operational units. Bulk cargo remains viable for budget-driven, single-unit exports, while Flat Rack is essential for non-standard configurations. Universal application of wax-based anti-corrosion treatment is non-negotiable to preserve equipment integrity across all methods.
SEA LION International recommends pre-qualifying logistics partners based on RO-RO availability, corrosion protection compliance, and terminal handling certifications.
