HD-MT Series Heavy Duty Mining Truck
Prepared for Fleet Managers & Construction Operations Leadership

---

EXECUTIVE OVERVIEW

SEA LION International presents the HD-MT Series – a purpose-engineered heavy-duty mining truck platform designed for extreme-duty cycles in open-pit mining, bulk material logistics, and large-scale civil construction. This specification report details the operational and technical rationale for the HD-MT Series’ dominance in high-abrasion, remote, and climatically aggressive environments across Africa, Russia, and Southeast Asia (SEA).

The HD-MT Series (based on SINOTRUK HOWO TX/SHACMAN X3000/XCMG mining derivatives) delivers unmatched Total Cost of Ownership (TCO) optimization through three core pillars:
1. Payload Maximization: 105-120 tonne GVWR with reinforced chassis frames (yield strength ≥ 800 MPa) and multi-axle configurations (6×4, 8×4) for unstable terrain.
2. Environmental Resilience: Validated operation in ambient ranges from -45°C (Russia) to +55°C (Africa/SEA) with integrated thermal management systems.
3. Maintenance Sustainability: 50,000 km service intervals and modular component design enabling field repairs with minimal tooling – critical for remote sites.

Regional Market Preference Drivers

Market	Key Operational Challenge	HD-MT Series Solution	TCO Impact Factor
Africa	Unpaved haul roads; 45°C+ ambient; limited service infrastructure	Heavy-duty suspension (parabolic leaf springs); desert-grade air filtration (99.9% efficiency); simplified electrical architecture	22% lower downtime vs. competitors
Russia	Permafrost instability; -40°C operation; short daylight cycles	Arctic-spec engine block heater (-50°C start); reinforced cab insulation; low-temperature hydraulic fluid	30% faster cycle times in winter
SEA	Monsoon conditions; high humidity; corrosive soils	Zinc-nickel coated undercarriage; IP67-rated electronics; corrosion-resistant hydraulic seals	40% reduction in body corrosion failures

SEA LION International Value Integration

As an authorized distributor for SINOTRUK, SHACMAN, and XCMG with 18+ years in global heavy truck deployment, SEA LION eliminates critical supply chain risks for these markets:

• Refurbishment Assurance: All HD-MT units undergo ISO 9001-certified refurbishment at SEA LION hubs (Jingzhou, Qingdao), including engine/transmission rebuilds to OEM tolerances and structural integrity validation via ultrasonic testing.
• Spare Parts Continuity: Direct access to 120,000+ OEM part SKUs with 98.5% availability; strategic warehousing in Durban, Vladivostok, and Singapore enabling <72-hour critical part delivery.
• Logistics Execution: Dedicated RO-RO vessel slots and containerized component shipping (ISO tank containers for fluids) ensuring on-time site arrival – reducing project ramp-up delays by 15-20 days.

Conclusion

The HD-MT Series is not merely a transport asset but a production-critical system engineered for the specific geomechanical and climatic extremes defining African, Russian, and Southeast Asian resource projects. SEA LION International’s integrated model – combining OEM-grade refurbishment, parts sovereignty, and industrial logistics – transforms truck procurement from a capital expense into a predictable operational enabler. For fleet managers prioritizing uptime in volatile environments, the HD-MT Series delivers verifiable TCO leadership validated across 2,300+ deployed units in target regions (2023-2025 field data).

This specification supersedes all prior documentation. Technical appendix (Section 4.1) contains full test protocols and regional adaptation schematics.

Performance Analysis

Load Capacity

The HD-MT350 is rated for a maximum payload of 35 metric tons (77,162 lbs) under standard operating conditions. The tandem rear axle configuration (2×18,000 kg) ensures even load distribution and reduced ground pressure, critical for maintaining traction and minimizing tire wear on rough haul roads. The high GVW rating and robust frame design support extended service life in 24/7 operations.

Payload optimization is further enhanced by a low-tare weight of 18,500 kg, delivering a payload-to-tare ratio of 1.89:1, which exceeds industry benchmarks for rigid dump alternatives in the same class.

---

Fuel Efficiency

Fuel economy is optimized through calibrated engine mapping and transmission gearing:

• Average Fuel Consumption: 38–42 L/100 km (6.2–5.6 US mpg) under mixed load conditions (25–32 ton payload, 10% grade).
• Best-in-Class Efficiency: Achieved via Weichai WD615’s high-efficiency combustion system and HW19710’s close-ratio gear spacing, minimizing RPM drop between shifts.
• Idle Reduction: Integrated engine auto-shutdown (configurable) reduces idle fuel burn by up to 18% in queuing operations.

Fleet telemetry integration (optional) enables real-time fuel monitoring and driver behavior analysis, supporting long-term cost control.

---

Operational Recommendations

• Tire Maintenance: Inspect 12.00R20 tires weekly for cuts, tread depth (<4 mm requires replacement), and inflation (10 bar / 145 psi recommended).
• Transmission Use: Utilize full 10-speed range; avoid skip-shifting to reduce clutch and synchro wear.
• Engine Service: Follow Weichai-recommended intervals (10,000 km oil change, 20,000 km fuel filter) with low-ash CK-4 lubricants.
• Duty Cycle Suitability: Ideal for haul distances ≤ 5 km and grades ≤ 12%. Not recommended for continuous high-speed highway transit.

---

Conclusion

The HD-MT350 Heavy Duty Mining Truck delivers a balanced combination of high payload capacity, proven mechanical reliability, and competitive fuel efficiency. With the Weichai WD615 engine and HW19710 transmission, it offers low total cost of ownership for medium-scale mining and heavy construction fleets operating in demanding environments. Its standardized componentry ensures global serviceability and reduced downtime.

---

4. Corrosion Protection: Wax Spraying System

4.1 Requirement

Extended exposure to salt-laden marine atmospheres during transit poses a high risk of corrosion to exposed metal surfaces, hydraulic components, and undercarriage assemblies.

4.2 Recommended Solution: Industrial Wax Encapsulation

A solvent-based, hydrophobic corrosion-inhibiting wax is applied via automated spray system prior to shipment.

Property	Specification
Application Method	High-pressure electrostatic spray
Coating Thickness	50–75 µm (uniform coverage)
Salt Spray Resistance (ASTM B117)	>1,000 hours
Temperature Range	-40°C to +90°C
Removal Process	Biodegradable solvent washdown
Coverage Areas	Frame rails, suspension joints, radiator core, exhaust manifolds, electrical connectors (sealed)

4.3 Advantages

• Forms moisture barrier without affecting mechanical tolerances
• Self-healing properties under vibration
• Compatible with painted and bare metal substrates
• Reduces post-delivery rework by up to 60% (based on 2025 field data)

---

5. Recommendations

Use Case	Preferred Method	Rationale
Single-unit delivery, operational readiness	RO-RO	Fast deployment, minimal handling, lower labor cost on arrival
Multi-unit tender, budget-constrained	Bulk Cargo	Lowest freight cost; requires local assembly capability
Prototype or high-value unit, precision load	Flat Rack	Maximum control over securing, visibility, and reduced point-load stress

Mandatory: All units must undergo wax spraying treatment regardless of shipping method. SEA LION-certified application centers are available in Shanghai, Qingdao, and Guangzhou.

---

6. Compliance & Documentation

• ISM Code and IMDG Code adherence enforced
• CIQS (China Inspection and Quarantine) certification required for export
• Bill of Lading, Packing List, and Wax Treatment Certificate to accompany shipment

---

7. Conclusion

For fleet managers and construction logistics planners, the selection of shipping method must balance cost, delivery timeline, and equipment integrity. While RO-RO offers optimal balance for most HDMT exports, Flat Rack ensures maximum protection for sensitive units. Bulk Cargo remains viable only when local reassembly infrastructure is confirmed. In all cases, industrial wax spraying is non-negotiable for corrosion mitigation and long-term asset preservation.
