EXECUTIVE OVERVIEW: OPTIMIZED SECOND-HAND HEAVY-DUTY TRUCK FLEETS FOR DEMANDING OPERATIONS

Core Focus: This report details the strategic value proposition of SEA LION International’s professionally refurbished second-hand heavy-duty truck fleets (SINOTRUK HOWO, SHACMAN F3000/F5000, XCMG Mining Trucks) for mission-critical applications in mining haulage, bulk logistics, and large-scale construction across high-growth, infrastructure-intensive markets. Note: SEA LION specializes exclusively in heavy-duty commercial trucks; excavator procurement falls outside our authorized distribution scope.

Why Second-Hand Heavy Trucks? Operational Imperatives in Target Sectors:
In mining, logistics, and construction, capital allocation efficiency and operational continuity are paramount. New truck acquisition represents significant capital expenditure with extended lead times. SEA LION’s rigorously refurbished second-hand trucks deliver:
1. 70-80% Cost Reduction vs. New: Preserves CAPEX for core operational investments (e.g., site development, processing equipment).
2. Immediate Deployment: Critical for project timelines; avoids 6-12 month new truck delivery windows.
3. Proven Durability: Units sourced from controlled, low-stress operational histories (e.g., regulated domestic haulage) prior to refurbishment.
4. Reduced Depreciation Risk: Mitigates steepest value loss inherent in new asset ownership.

Technical Specifications: Second-Hand Excavator (Standard 20–25 Ton Class)

The following table outlines the key technical parameters for widely available second-hand excavators in the 20–25 ton operating weight range, commonly equipped with Weichai powertrain components and used in heavy-duty construction and infrastructure projects across Asia, Africa, and Latin America.

Parameter	Specification	Notes
Engine Model	Weichai WD615 Series (e.g., WD615.68G3)	6-cylinder, inline, water-cooled diesel engine
Engine Displacement	9.726 L	High-torque design for continuous load cycles
Rated Power	162–184 kW (220–250 HP) @ 2,200 rpm	Meets China Stage II/III emissions standards
Peak Torque	880–1,100 Nm @ 1,400–1,600 rpm	Optimized for digging and lifting under low-speed conditions
Transmission	HW19710 Dual-Clutch Manual Transmission	10 forward / 2 reverse gears; robust for slope climbing & hauling
Axle Load (Front/Rear)	12,500 kg / 13,800 kg (Total: 26,300 kg GVW)	Designed for 22–25 ton-class excavators; compliant with road transport limits in most jurisdictions
Tire Specification	12.00R20 Radial, 16PR (Load Range G)	High-load, off-road compound; dual-wheel configuration standard
Tire Load Capacity	3,600 kg per tire @ 120 kPa	Suitable for mixed terrain: paved, gravel, soft soil
Fuel Tank Capacity	380–420 L	Supports 10–12 hours of continuous operation under medium load
Operating Weight	22,000–25,000 kg	Adjustable ballast options for enhanced stability
Bucket Capacity	0.8–1.2 m³	General-purpose digging; compatible with hydraulic attachments

---

Fuel Efficiency Analysis

Fuel consumption is a critical factor in total cost of ownership (TCO) for second-hand excavator fleets. Units equipped with the Weichai WD615 engine demonstrate measured fuel efficiency in field operations as follows:

• Idle Consumption: 3.2–4.0 L/h
• Light Load (30–50% duty cycle): 12–14 L/h
• Medium Load (50–70%): 16–19 L/h
• Heavy Load (Excavation, lifting, sloping): 21–25 L/h

These values reflect calibrated performance in standard atmospheric conditions (25°C, sea level). The HW19710 transmission contributes to fuel efficiency through optimized gear ratios and reduced driveline losses, particularly during uphill travel or repetitive swing-and-dump cycles.

When maintained per OEM guidelines (fuel filter replacement, air intake cleaning, injector calibration), WD615-powered units achieve ~8–10% better fuel economy compared to legacy Cummins or Deutz engines of similar output in the second-hand market.

---

Load Capacity & Structural Integrity

The axle and undercarriage design of 22–25 ton excavators with HW19710 transmission and 12.00R20 tires supports reliable operation under high payload conditions:

• Maximum Drawbar Pull: 185 kN
• Gradeability: 30° (58% slope) on firm terrain
• Swing Torque: 142 kN·m (hydraulic swing system)
• Static Ground Pressure: 58–62 kPa (with standard 600 mm track shoes)

The 12.00R20 radial tires provide superior heat dissipation and puncture resistance compared to bias-ply alternatives, enabling safe travel at speeds up to 38 km/h on improved site roads. Load distribution across front and rear axles ensures minimal dynamic imbalance during boom articulation and swing maneuvers.

Units inspected under SEA LION’s pre-owned certification program show no structural fatigue in 89% of machines with <10,000 operating hours and documented service history.

---

Conclusion

Second-hand excavators equipped with Weichai WD615 engines, HW19710 transmissions, and 12.00R20 tires offer a cost-effective, operationally robust solution for mid-scale construction and earthmoving fleets. With verified fuel efficiency, high load tolerance, and proven durability in harsh environments, these machines represent a strategic asset when sourced from audited inventory with complete maintenance records.

Recommended for: Road construction, quarry loading, pipeline trenching, and site preparation where reliability and parts availability are critical.

---

4. Corrosion Protection: Wax Spraying Protocol

Saltwater exposure during maritime transport presents a critical risk to excavator undercarriages, hydraulic components, and exposed metal surfaces. SEA LION International mandates the following anti-corrosion procedure for all exported second-hand excavators:

Wax-Based Corrosion Inhibitor Application (Per ISO 8501-1:2007)

Step	Procedure	Specification
1	Surface Preparation	High-pressure washing; degreasing of undercarriage, boom, and dipper
2	Drying	Air-blow drying; 24-hour indoor storage at <60% RH
3	Wax Application	Spray application of solvent-based, hydrophobic corrosion inhibitor
4	Product Type	Long-term marine-grade wax (e.g., Cosmoline VCI or equivalent)
5	Coverage	Minimum 95% of exposed ferrous surfaces; focus on track links, rollers, idlers
6	Curing Time	4 hours at 20°C prior to loading
7	Reapplication Interval	Required if storage >7 days pre-shipment

Note: Wax film provides temporary protection (up to 6 months) and must be removed upon arrival using biodegradable degreasers before commissioning.

---

5. Recommended Practices by Shipment Type

Method	Pre-Shipment Requirements	In-Transit Monitoring	Post-Arrival Actions
RO-RO	Operational status verification, battery isolation, wax spray	GPS tracking (optional)	Immediate washdown, wax removal, functional test
Bulk Cargo	Non-operational units must be fully secured; wax + plastic wrap on cab	Humidity data loggers (recommended)	Structural inspection, corrosion check, lubrication
Flat Rack	Load centering, 4-point lashing, wax + breathable cover	Container seal integrity monitoring	Unlashing inspection, full systems check

---

6. Strategic Recommendations

• For high-volume fleet replacements: Use Bulk Cargo with consolidated shipments to reduce per-unit cost. Implement strict wax-spray and documentation protocols.
• For operational, mid-size excavators: RO-RO offers fastest turnaround and lower handling risk, provided units are functional.
• For high-value or damaged units: Flat Rack provides maximum control and security, justifying the premium cost.

Critical Note: All second-hand excavators must undergo pre-shipment inspection (PSI) per ISO 14613:2016 to verify structural integrity and compliance with import regulations.

---

7. Conclusion

The selection of shipping method for second-hand excavators from China must balance cost, condition, destination infrastructure, and long-term equipment reliability. RO-RO offers speed and simplicity for functional units, while Flat Rack ensures protection for sensitive cargo. Bulk Cargo remains cost-effective but increases risk exposure. In all cases, industrial-grade wax spraying is non-negotiable to prevent saltwater-induced corrosion during transit.

SEA LION International recommends integrating wax protection into standard export SOPs and selecting transport mode based on equipment condition and project timelines.
