Fuel Efficiency Analysis

Fuel economy in WD615-powered units operating under mixed Michigan conditions (highway, rural roads, and construction site ingress/egress) averages:

• On-Highway (Loaded 80%): 3.8–4.2 km/L (9–10 MPG)
• Urban/Construction Cycle: 2.6–3.1 km/L (6–7.3 MPG)
• Idling Fuel Consumption: ~1.8 L/hr at 800 rpm

The Weichai WD615 engine features electronically controlled high-pressure common rail (HPCR) injection and optimized combustion chambers, contributing to improved fuel atomization and thermal efficiency. When paired with the HW19710’s close-ratio top gears, trucks achieve efficient cruise control at 65–70 mph with engine RPM maintained at ~1,600.

Note: Units with updated ECM calibrations (post-2022 rebuilds) show up to 6% better fuel efficiency due to optimized shift mapping and reduced parasitic losses.

---

Load Capacity & Structural Integrity

These trucks are engineered for high-cycle, heavy-load operations typical in Michigan’s aggregate, logging, and infrastructure sectors.

• Maximum Payload Capacity: 28,000–31,000 kg (61,700–68,300 lbs), depending on body configuration
• Dump Body Compatibility: Up to 20 m³ volumetric capacity (standard rigid dump bodies)
• Towing Capacity: 35,000 kg (77,160 lbs) with proper braking setup (SAE J2807 compliant)

The tandem rear axle system with 13T drop-center axles provides superior weight distribution and reduced ground pressure, critical for operation on soft or thaw-affected substrates common in Upper Peninsula and spring thaw zones.

Tire specification 12.00R20 18PR ensures durability under sustained 80,000 GVWR operation, with high resistance to cuts and heat buildup. These tires are interchangeable with major OEMs (Michelin XZE, Goodyear G288) and widely available across Michigan’s commercial tire network.

---

Operational Recommendations

• Maintenance Interval: Oil & filter every 15,000 km; fuel filter every 10,000 km
• Transmission Service: HW19710 requires GL-5 85W-90 gear oil; shift linkage inspection every 20,000 km
• Axle Lubrication: 8.0L per rear axle; check differential breather monthly in dusty environments
• Cold Weather Suitability: All units evaluated include engine block heaters and cold-rated lubricants (SAE 10W-30/15W-40)

---

Conclusion

Used trucks equipped with the Weichai WD615 engine and HW19710 transmission, featuring 12.00R20 tires and robust 26T rear axle load capacity, represent a cost-effective solution for Michigan-based fleets requiring high durability and ease of maintenance. With proven performance in regional haul and off-road construction logistics, these units deliver optimal balance between load capacity, fuel efficiency, and lifecycle cost. Pre-purchase inspection should include ECM diagnostics, clutch wear assessment, and axle seal integrity checks to ensure operational readiness.

Shipping & Logistics Solutions

Industrial Specification Report 2026

Prepared by: SEA LION International
Subject: Export Logistics Solutions for Used Trucks from China to Michigan, USA
Target Audience: Fleet Managers, Construction Equipment Procurement Officers

---

Executive Summary

This report evaluates industrial-grade maritime logistics solutions for the export of used trucks from Chinese ports to Michigan, USA. As demand grows for cost-effective, pre-owned heavy-duty vehicles in North American construction and transport sectors, optimizing export logistics is critical. SEA LION International presents a comparative analysis of three primary shipping methods—Roll-on/Roll-off (RO-RO), Bulk Cargo, and Flat Rack (Containerized)—with technical specifications, cost-efficiency metrics, and corrosion protection protocols, including wax-based anti-seawater coatings.

---

1. Export Origin & Destination Context

Parameter	Detail
Origin Ports (China)	Shanghai, Qingdao, Guangzhou, Ningbo
Destination (USA)	Detroit, MI (Inland via Great Lakes St. Lawrence Seaway)
Average Transit Time	28–36 days (Port-to-Port)
Cargo Type	Used Heavy-Duty Trucks (5–15 years old, 8–20 tons GVW)
Volume per Shipment	10–50 units per batch

---

2. Comparative Shipping Method Analysis

Criteria	RO-RO (Roll-on/Roll-off)	Bulk Cargo	Flat Rack Container
Loading Mechanism	Self-propelled or towed onto vessel	Loosely stowed in hold; secured with lashings	Secured on open-top flat rack (20′ or 40′)
Vehicle Integrity	High (minimal handling)	Medium (risk of shifting, abrasion)	High (controlled immobilization)
Space Utilization	High (optimized deck stacking)	Very High (maximized hold volume)	Low-Medium (limited by container availability)
Port Accessibility	Limited to RO-RO-capable terminals	Widely accessible	Requires container-handling infrastructure
Transit Risk (Damage)	Low (controlled roll-in/out)	High (cargo movement, moisture)	Medium (exposure to elements)
Insurance Cost	Moderate	High	Moderate-High
Average Cost per Unit (USD)	$1,200–$1,600	$900–$1,300	$1,800–$2,400
Best For	Operational trucks, quick turnaround	Non-operational units, high volume	Oversized loads, custom configurations

Note: While Bulk Cargo offers lowest per-unit cost, it poses the highest risk of mechanical and cosmetic damage during transit.

---

3. Corrosion Protection: Wax Spraying Protocol

Marine environments expose metal surfaces to salt-laden air and condensation, accelerating oxidation. To mitigate seawater-induced corrosion during trans-Pacific and Great Lakes transit, SEA LION International mandates industrial-grade wax spraying as a standard preservation measure.

Wax Spraying Specifications:

Parameter	Specification
Coating Type	Solvent-based synthetic wax (non-drying, self-healing)
Application Method	Electrostatic spray + brush detailing
Coverage Areas	Undercarriage, frame rails, suspension components, wheel hubs, exhaust mounts
Thickness	15–25 µm (uniform film)
Salt Spray Resistance (ASTM B117)	>500 hours
Removal	Biodegradable citrus-based cleaner (post-delivery)
Compliance	ISO 9227, JIS Z 2371

Operational Benefit: Wax film prevents moisture penetration, reduces pitting on high-stress steel components, and maintains resale value.

---

4. Recommended Solution by Use Case

Client Profile	Recommended Method	Rationale
Fleet Managers (High Volume, Operational Trucks)	RO-RO + Wax Spray	Fast loading, minimal wear, rapid deployment upon arrival
Construction Firms (Oversized Equipment, Cranes, Mixers)	Flat Rack + Wax Spray	Accommodates non-standard dimensions, secure lashing
Budget-Focused Buyers (Non-Running Units)	Bulk Cargo + Wax Spray	Lowest cost; wax mitigates storage corrosion during extended transit

---

5. Compliance & Documentation

All shipments comply with:
– IMSBC Code (for Bulk)
– IMDG Code (if batteries/fuels present)
– US EPA & DOT Import Standards
– Chinese Customs Export Declarations (Form E)
– Certificate of Origin, Bill of Lading, Pre-shipment Inspection (PSI)

---

6. Conclusion

For used truck exports from China to Michigan, RO-RO shipping offers the optimal balance of cost, safety, and efficiency for operational fleets. Flat Rack remains indispensable for non-standard vehicles, while Bulk Cargo suits budget-restricted, non-running units—provided enhanced corrosion protection is applied.

SEA LION International mandates wax-based anti-corrosion treatment across all shipment types to ensure structural integrity and compliance with North American fleet maintenance standards.

Future logistics planning should integrate port-to-yard tracking, real-time humidity monitoring, and automated wax quality verification to further reduce total cost of ownership.
