Performance Analysis
Fuel Efficiency
The WD615 Weichai engine is calibrated for optimal fuel economy under variable load conditions. Under mixed operating cycles (digging, traveling, floating), the average fuel consumption is 22.5 L/h at 75% load. At idle, consumption drops to 7.8 L/h, enhancing efficiency during transition or positioning phases. Advanced high-pressure common rail (HPCR) injection and ECU-based load sensing result in 12–15% improvement in fuel efficiency compared to previous-generation models.
Field data from 2025 pilot deployments in Jiangsu and Louisiana wetland projects confirmed an average fuel efficiency of 0.98 L per ton-meter moved, making it suitable for cost-sensitive, high-utilization environments.
Load Capacity & Structural Integrity
The SL-AEX750 is engineered for maximum payload stability in both terrestrial and aquatic conditions:
– Digging Force (Bucket): 185 kN
– Swing Torque: 112 kN·m
– Max Lift Capacity (at Ground Level, 5m radius): 6,200 kg
– Buoyant Displacement: 28,000 kg (enables stable operation in water depths up to 1.8 m)
The reinforced floating undercarriage, constructed from high-tensile S460ML steel, supports full operational loads with a safety factor of 2.3:1 under ISO 10977-1 compliance. Axle load distribution is optimized to prevent ground pressure exceedance, with maximum ground pressure of 0.48 kg/cm², minimizing subsidence in soft terrain.
Operational Advantages for Fleet Deployment
- Transmission Reliability: The HW19710 gearbox offers proven durability in extreme-duty applications, with over 10,000-hour MTBF (Mean Time Between Failures) in comparative fleet studies.
- Tire Performance: 12.00R20 radial tires provide extended tread life (avg. 3,200 hrs on mixed terrain), reduced rolling resistance, and enhanced puncture resistance due to cut-proof sidewall compound.
- Maintenance Intervals: 500-hour oil change cycles (engine & transmission), centralized greasing system, and modular component layout reduce downtime by up to 30%.
Conclusion
The SL-AEX750 amphibious excavator delivers a balanced combination of high horsepower, efficient fuel use, and superior load-handling capability, making it ideal for infrastructure, environmental remediation, and flood control operations. Its standardized Weichai powertrain and HW19710 transmission ensure parts availability and service compatibility across global markets.
Recommended for fleet integration where multi-environment adaptability and operational cost control are critical.

Shipping & Logistics Solutions
Industrial Specification Report 2026
Prepared for: Fleet Managers & Construction Companies
Subject: Logistics Solutions for Exporting Amphibious Excavators from China
Document ID: ISR-2026-LOG-EXC-001
Date: 2026-04-05
1. Executive Summary
This report evaluates three primary maritime transport methods—RO-RO (Roll-on/Roll-off), Bulk Cargo, and Flat Rack container shipping—for the export of amphibious excavators from manufacturing hubs in China (e.g., Shanghai, Qingdao, Xiamen) to global construction and infrastructure project sites. The analysis focuses on cost efficiency, equipment integrity, transit time, and corrosion protection protocols, with specific emphasis on long-term exposure to marine environments during transit.
Amphibious excavators, due to their specialized undercarriage, sealed hydraulic systems, and corrosion-prone metallic components, require stringent handling and environmental protection during shipping. This report recommends optimal logistics strategies based on operational scale, destination port infrastructure, and equipment value.
2. Equipment Overview
| Parameter | Specification |
|---|---|
| Equipment Type | Amphibious Excavator |
| Operating Weight Range | 8,000 – 22,000 kg |
| Dimensions (L×W×H) | 9.5m × 3.2m × 3.0m (avg.) |
| Undercarriage Type | Pontoon-based, sealed flotation chambers |
| Hydraulic System | Marine-grade corrosion-resistant seals |
| Export Origin | Major Chinese ports (Shanghai, Qingdao, Nansha) |
| Typical Destinations | Southeast Asia, Middle East, Africa, Latin America |
3. Comparative Shipping Methods
| Criteria | RO-RO (Roll-on/Roll-off) | Bulk Cargo (Lo-Lo) | Flat Rack Container |
|---|---|---|---|
| Loading Mechanism | Self-propelled or towed onto vessel | Lifted by port crane (Lo-Lo) | Secured on open-top flat rack, crane-lifted |
| Cargo Protection | Moderate (exposed deck; weather risk) | Low (exposed to salt spray, humidity) | High (enclosed or tarp-covered; customizable) |
| Corrosion Risk | High (direct seawater exposure) | Very High (prolonged open-deck storage) | Low to Moderate (with wax spray protection) |
| Lashing & Securing | Standard marine chains, wheel chocks | Minimal; relies on onboard crane stability | Engineered lashing points, twist locks |
| Transit Time (Asia → ME) | 10–14 days | 18–25 days | 14–18 days |
| Port Infrastructure Req. | RO-RO-capable terminal (ramp access) | General cargo crane availability | Container crane + flat rack handling |
| Cost (per unit, USD) | $1,800 – $2,500 | $1,200 – $1,800 | $3,000 – $4,200 |
| Best For | High-volume, time-sensitive shipments | Low-value, non-sensitive equipment | High-value, corrosion-sensitive units |
4. Corrosion Protection: Wax Spraying Protocol
Due to prolonged exposure to saline maritime environments, amphibious excavators are highly susceptible to galvanic and crevice corrosion, particularly on undercarriage pontoons, track links, and hydraulic cylinder rods.
Recommended Protection: Industrial Wax Spraying (ISO 8501-1:2007 Compliant)
| Parameter | Specification |
|---|---|
| Coating Type | Solvent-based anti-corrosion wax (e.g., Cosmoline VCI, Henkel Techniclean) |
| Application Method | Pressurized spray + brush touch-up on joints |
| Coverage Areas | Undercarriage, track rollers, hydraulic joints, unpainted steel surfaces |
| Thickness | 50–75 µm (dry film) |
| Salt Spray Resistance | 500+ hours (ASTM B117) |
| Removal Process | Biodegradable degreaser + high-pressure wash |
| Reapplication Interval | Pre-shipment only (single application) |
Note: Wax spraying is mandatory for all Flat Rack and RO-RO shipments exceeding 10 days at sea. Bulk cargo units must receive double-coating due to higher exposure risk.
5. Risk Assessment & Mitigation
| Risk Factor | RO-RO | Bulk Cargo | Flat Rack | Mitigation Strategy |
|---|---|---|---|---|
| Seawater Ingress | Medium | High | Low | Wax spray + sealed hydraulic caps |
| Structural Damage | Low | Medium | Low | Reinforced lashing, load distribution mats |
| Theft/Vandalism | Medium | High | Low | GPS tracking, sealed container locks |
| Delay at Port | Low | High | Medium | Pre-booked terminal slots, customs pre-clearance |
| Insurance Claims Frequency | 3.2% | 6.8% | 1.9% | Full documentation, condition reports pre-load |
6. Recommendations
-
For High-Value Fleets (≥5 units): Use Flat Rack containers with wax spraying. Ensures maximum protection, traceability, and compliance with international construction equipment import standards (e.g., GCC, CE, EPA).
-
For Rapid Deployment Projects: RO-RO is optimal if destination port supports roll-on/off operations. Apply wax spray and conduct post-arrival inspection for corrosion.
-
Avoid Bulk Cargo unless cost is the overriding factor and equipment is intended for short-term use with immediate refurbishment.
-
Mandatory Pre-Shipment Protocol: All units must undergo:
- Full wax spray corrosion protection
- Hydraulic system pressure test
- Battery isolation and fuel stabilization
- GPS-enabled telematics installation
7. Conclusion
Exporting amphibious excavators from China demands a balanced approach between cost, transit efficiency, and long-term equipment integrity. While RO-RO offers speed and operational simplicity, Flat Rack shipping—combined with industrial wax spraying—provides superior protection against seawater corrosion and is recommended for premium equipment destined for harsh environments. Bulk Cargo remains a high-risk, low-cost alternative unsuitable for modern, high-specification machinery.
Logistics planning must integrate corrosion control as a core component of asset preservation, ensuring operational readiness upon delivery.
