– Predictive cruise control (optional)
– Low-rolling-resistance radial tires (12.00R20 G-rated)
– Aerodynamic cab design (drag coefficient: 0.68 Cd)
Annual fuel savings of up to 12% are observed compared to legacy Euro IV platforms under identical operational profiles.
Load Capacity & Operational Suitability
These vehicles are engineered for integration into excavator-led workflows, particularly for:
- Hauling bulk materials (soil, rock, aggregate) from dig sites
- Transporting mini and mid-size excavators (up to 22-ton class) via low-bed trailers
- Supporting deep excavation dewatering and spoil removal cycles
Maximum Payload Capacity:
– 21,500 kg (47,400 lbs) on paved or compacted gravel roads

Shipping & Logistics Solutions
Industrial Specification Report 2026
Prepared for: Fleet Managers & Construction Companies
Subject: Export Logistics Solutions for Excavator Contractors from China
Issuing Authority: SEA LION International – Engineering & Logistics Division
Executive Summary
This report evaluates three primary maritime transport methods for exporting excavator contractors (tracked and wheeled) from manufacturing hubs in China to global project sites: Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (FR) Containers. Performance metrics include cost efficiency, transit integrity, handling speed, and corrosion mitigation. A standardized wax-based anti-corrosion treatment is recommended across all methods to mitigate seawater exposure during transit.
1. Transport Method Comparison
| Criterion | RO-RO Shipping | Bulk Cargo Shipping | Flat Rack (FR) Container |
|---|---|---|---|
| Equipment Compatibility | Tracked excavators, self-propelled | All types (disassembled) | All types (fully secured) |
| Loading Mechanism | Self-driven or towed onto vessel | Craned into open hold | Craned and lashed on flat rack |
| Transit Time (Asia → EU/ME/AF) | 28–35 days | 32–40 days | 30–38 days |
| Port Infrastructure Needs | RO-RO ramps, clear approach paths | Heavy-lift cranes, open storage | Container cranes, lash teams |
| Damage Risk (High/Med/Low) | Low (minimal handling) | High (crane handling, stacking) | Medium (lashing failure risk) |
| Cost per Unit (USD) | $2,800–$3,500 | $1,900–$2,600 | $3,400–$4,200 |
| Insurance Premiums | Lower (predictable loading) | Higher (handling exposure) | Moderate |
| Customs Clearance | Fast (pre-staged documentation) | Variable (depends on port) | Standard container protocols |
| Scalability (Fleet Export) | High (up to 50 units/vessel) | High (loose cargo capacity) | Moderate (container availability) |
Note: Costs are average estimates for standard 20–35 ton excavators from Shanghai/Ningbo to Rotterdam, Jebel Ali, or Durban (Q2 2026 rates).
2. Corrosion Protection: Wax Spraying Protocol
Marine environments expose metallic surfaces to salt-laden air and condensation, accelerating corrosion on excavator undercarriages, hydraulic cylinders, and structural joints.
Recommended Anti-Corrosion Solution:
- Treatment: Application of synthetic wax-based corrosion inhibitor (e.g., DINITROL 4490, COSMOL 2110) pre-shipment.
- Coverage Areas:
- Track links, rollers, idlers, and sprockets
- Boom/stick pivot points
- Exposed hydraulic rams
- Underframe and chassis cavities
- Application Method:
- Pressure spray (20–30 bar)
- Minimum 15 μm dry film thickness
- Ambient temperature >10°C during application
- Duration of Protection: Up to 6 months under sealed conditions
- Post-Transit Removal: Biodegradable solvent wash or steam cleaning (non-abrasive)
Compliance: Meets ISO 9227 (salt spray testing) and ASTM D1748 (humidity resistance).
3. Method-Specific Risk Assessment
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack |
|---|---|---|---|
| Seawater Exposure | Moderate (decks exposed) | High (hold condensation) | High (open-sided) |
| Physical Impact | Low | High (cargo shifting) | Medium (improper lashing) |
| Theft/Vandalism | Low (secured decks) | High (open holds) | Low (container seal integrity) |
| Weather Delays | Medium (vessel scheduling) | High (port congestion) | Medium |
| Reassembly Required | None | Yes (if disassembled) | None |
4. Recommendations by Use Case
| Client Profile | Recommended Method | Rationale |
|---|---|---|
| Large-scale fleet deployment (≥10 units) | RO-RO | Fast turnaround, low handling damage, cost-effective at scale |
| Remote site delivery, limited port access | Flat Rack | Intermodal compatibility (ship → rail → truck), ISO container handling |
| Budget-constrained projects, non-urgent | Bulk Cargo (disassembled) | Lowest cost; suitable for rebuild at destination |
5. SEA LION International Compliance & Certification
All export operations adhere to:
– IMDG Code (for hazardous materials, e.g., fuel/lubricants)
– CSS Code (Cargo Securing Manual compliance)
– China MOC Regulations (export of heavy machinery)
– ISO 1496-4 (Flat rack container standards)
Wax treatment applied at SEA LION-certified pre-shipment facilities in Ningbo, Qingdao, and Guangzhou.
Conclusion
For high-integrity, time-sensitive exports of excavator contractors from China, RO-RO shipping provides optimal balance of cost, safety, and speed. Flat Rack containers offer superior protection for high-value units destined for intermodal routes. Bulk cargo remains viable only for cost-driven, non-urgent shipments with on-site reassembly capacity. Universal application of wax-based corrosion protection is non-negotiable for all sea-exported equipment to ensure operational readiness upon arrival.
