Equipment Model: XCMG 310-Class Hydraulic Excavator (Model Designation: XE310)
Prepared For: Fleet Managers & Construction Operations Leadership
Issuing Authority: SEA LION International Trade Co., Ltd. (Authorized XCMG Distributor)
1. CORE APPLICATION & PERFORMANCE
The XCMG XE310 excavator (31.5-tonne operating weight class) is engineered for high-intensity material handling, trenching, and loading operations in mining overburden removal, heavy civil construction, and bulk logistics terminals. Its design prioritizes fuel efficiency under sustained load, hydraulic responsiveness for repetitive cycles, and structural durability in abrasive environments. Key technical differentiators include:
| Parameter | Specification | Operational Impact |
|---|---|---|
| Engine | Cummins QSB7 Tier 3 | 180 kW @ 1,800 rpm; optimized for low-octane diesel |
| Digging Force (BCM) | 225 kN | Efficient in cohesive soils & fragmented rock |
| Hydraulic System | Dual-pump variable | 320 L/min flow; reduces cycle time by 8-12% vs. peers |
| Undercarriage | XCMG Heavy-Duty | 700mm triple-sealed track; 15% longer life in rocky terrain |
| Fuel Consumption | 28-32 L/hr (avg.) | Validated in 500+ hr field tests @ 70% load factor |
2. REGIONAL MARKET PREFERENCE: AFRICA, RUSSIA, SOUTHEAST ASIA
The XE310 demonstrates superior operational economics in target regions due to climate-specific engineering adaptations and service ecosystem compatibility. SEA LION’s 18-year export experience validates consistent preference over competing platforms:
| Region | Critical Requirement | XE310 Implementation | SEA LION Value-Add |
|---|---|---|---|
| Africa | Dust ingress resistance | IP68-rated hydraulic filters; sealed cab (99.9% particulate retention) | Refurbishment protocol includes desert-spec undercarriage rebuilds |
| Russia (Siberia) | Extreme cold operation | -40°C cold-start system; arctic-grade hydraulics; heated operator station | Pre-winterization kits & localized spare parts hubs in Novosibirsk |
| Southeast Asia | High humidity/corrosion | Marine-grade undercarriage plating; non-ferrous hydraulic fittings | Corrosion-resistant refurbishment standard for all used units |
Why Preferred?
– Africa: Tolerates low-cetane diesel (min. 40 cetane) without derating; modular design simplifies field repairs with limited tools.
– Russia: Proven reliability at -35°C ambient (SAE J2267 validated); track tension auto-adjust compensates for frozen ground.
– Southeast Asia: Compact tail swing (3,250mm) enables operation in dense urban sites; corrosion mitigation extends service life by 22% vs. standard models.
3. SEA LION INTEGRATED SUPPORT ECOSYSTEM
As an authorized XCMG distributor with ISO 9001-certified refurbishment facilities, SEA LION addresses regional operational constraints through:
- Refurbishment Standard: All used XE310 units undergo 120-point inspection, including crack-tested booms, reconditioned main pumps, and replaced slewing bearings – extending residual life to 8,000+ hours.
- Parts Assurance: Direct OEM supply chain for genuine XCMG components; 98.5% in-stock rate for critical wear parts (bucket pins, track links).
- Logistics Optimization: RO-RO vessel deployment for Africa/Russia; containerized shipping for SE Asia with climate-controlled humidity control (<45% RH).
CONCLUSION
The XCMG XE310 delivers quantifiable TCO reduction in mining, logistics, and construction applications across Africa, Russia, and Southeast Asia through climate-hardened engineering, fuel-resilient powertrain design, and serviceability in remote conditions. SEA LION’s integrated model – combining certified refurbishment, OEM parts integrity, and region-optimized logistics – ensures 92%+ operational availability for fleet operators.

Subject: Export Logistics Solutions for ‘310 Excavator’ from China
Document ID: ISR-LOG-310EX-2026
Revision: 1.0
Date: 2026-04-05
Executive Summary
This report evaluates three primary maritime logistics methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack container shipping—for the export of the ‘310 Excavator’ from manufacturing hubs in China (e.g., Shanghai, Qingdao, Xiamen) to global project sites. The analysis focuses on cost efficiency, transit time, equipment integrity, and corrosion protection, with specific attention to wax-based anti-corrosion treatments to mitigate seawater exposure during ocean transit.
Equipment Overview: 310 Excavator
| Parameter | Specification |
|---|---|
| Model | 310 Excavator (Generic Class) |
| Operating Weight | 29,500 – 31,500 kg |
| Length | ~9.8 m |
| Width | ~3.1 m |
| Height | ~3.3 m (transport configuration) |
| Undercarriage Type | Tracked |
| Engine Power | 195 – 210 kW |
| Transport Preparation | Drained fluids, secured boom/stick |
Shipping Method Comparison
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Loose Stowage) | Flat Rack Container (20’/40′) |
|---|---|---|---|
| Loading Method | Self-propelled or towed on/off | Craned into hold, secured in place | Craned onto open-frame container |
| Suitability for 310 EX | High (if operational) | Medium (risk of shifting) | High (optimal for non-operational) |
| Cargo Protection | Moderate (exposed to hold environment) | Low (high exposure to moisture, salt) | High (with tarpaulin + wax coating) |
| Transit Time | Fast (direct port-to-port) | Moderate to Slow | Moderate (subject to container availability) |
| Port Infrastructure | Requires RO-RO terminal | General cargo terminal | Container terminal with heavy lift |
| Cost (USD, per unit) | $3,800 – $5,200 | $3,000 – $4,500 | $5,500 – $7,000 |
| Insurance Complexity | Low (standard RO-RO coverage) | High (custom stowage plans) | Medium (containerized, but open) |
| Risk of Damage | Low (controlled movement) | High (collision, moisture) | Low to Moderate (if properly secured) |
| Best For | Operational machines, speed | Cost-sensitive, non-urgent loads | High-value, non-operational units |
Note: Flat Rack offers best balance between protection and handling for non-operational 310 excavators. RO-RO is optimal if machine is functional and time-sensitive.
Corrosion Protection: Wax Spraying Protocol
Seawater exposure during transit (average 20–35 days) poses significant corrosion risk to hydraulic components, undercarriage rollers, and exposed metal surfaces.
Recommended Anti-Corrosion Procedure:
- Pre-Treatment Cleaning:
- Remove dirt, grease, and moisture from undercarriage and boom assemblies.
-
Dry all cavities using compressed air.
-
Wax-Based Coating Application:
-
Apply industrial-grade oil-wax displacement spray (e.g., Lanocote, Corrosion-X, or equivalent) to:
- Track links, rollers, idlers, and sprockets
- Boom/stick pins and bushings
- Hydraulic cylinder rods (after retraction)
- Exposed fasteners and weld joints
-
Coating Specifications:
- Penetration depth: ≥ 0.05 mm
- Salt spray resistance: > 500 hours (ASTM B117)
-
Temperature range: -30°C to +80°C
-
Post-Transit Removal:
- Wax is non-drying and removable with solvent or degreaser prior to commissioning.
- No residue damage to paint or seals when compliant products are used.
Compliance: Meets ISO 12944-2:2017 (Corrosion protection of steel structures) for temporary preservation during marine transport.
Recommendations
| Priority | Recommended Method | Rationale |
|---|---|---|
| Cost Efficiency | Bulk Cargo | Lowest base cost; suitable for inland delivery with local rigging |
| Speed & Simplicity | RO-RO | Fast loading/unloading; minimal port handling |
| Maximum Protection | Flat Rack + Wax Spraying | Superior environmental shielding; ideal for coastal/high-humidity destinations |
| Fleet-Wide Export | Mixed-mode (RO-RO + Flat Rack) | Balance cost, speed, and protection across large orders |
Conclusion
For the export of the 310 excavator from China, Flat Rack shipping combined with industrial wax spraying provides the highest level of corrosion protection and structural security, particularly for non-operational units. RO-RO remains the preferred method for operational machines where rapid deployment is critical. Bulk cargo is viable only when cost is the primary constraint and receiving port has adequate lifting and drying facilities.
All shipments should include mandatory wax-based corrosion inhibition as a standard preservation step, regardless of shipping mode, to ensure equipment integrity upon arrival.
