Performance Analysis

Fuel Efficiency

• Average Fuel Consumption: 28–33 L/100 km (8.5–7.1 mpg) under mixed load conditions (Denver to Front Range hauls).
• Fuel Efficiency Factors:
• Engine calibration optimized for torque over peak horsepower improves low-RPM efficiency.
• HW19710 transmission enables precise gear matching, reducing lugging and over-revving.
• At steady 55 mph on I-70 (elev. 5,000–7,500 ft), consumption stabilizes at ~30 L/100 km with 25-ton payloads.
• Use of aftermarket engine tuning (not recommended) may reduce efficiency by 8–12% due to improper air-fuel ratios.

Note: At Denver’s average elevation (~5,280 ft), naturally aspirated engines suffer derating, but the turbocharged WD615 maintains >92% of rated output due to forced induction.

Load Capacity & Structural Suitability

• Maximum Payload Capacity: 22–24 metric tons (48,500–52,900 lbs), depending on body configuration.
• Frame & Axle Durability: Designed for repetitive heavy-load cycles; common in aggregate, sand, and demolition debris transport.
• Tire Performance: 12.00R20 radial tires provide optimal balance of load-bearing (1,800 kg/tire), cut resistance, and heat dissipation for prolonged on/off-road use.
• Gradeability: Capable of maintaining 35 mph on 6% sustained grades (e.g., I-70 uphill to Eisenhower Tunnel) with full load.

---

Operational Recommendations

• Fleet Integration: Suitable for medium-duty construction logistics, short-haul dump, and aggregate transport. Not recommended for high-speed long-haul without transmission and cooling upgrades.
• Maintenance Protocol: Inspect turbocharger and EGR system (if equipped) every 20,000 miles. HW19710 requires gear oil change every 40,000 miles using SAE 80W-90 GL-5.
• Tire Management: Rotate every 15,000 miles; monitor for shoulder wear due to tight urban maneuvering.

---

Conclusion

Used trucks equipped with the Weichai WD615 engine and HW19710 transmission, fitted with 12.00R20 tires, represent a cost-effective solution for construction fleets in the Denver region. With verified load capacity up to 24 tons and acceptable fuel efficiency in high-altitude operations, these units offer strong ROI for non-CDL7 or secondary fleet roles. Structural robustness and parts availability (via third-party suppliers) further enhance operational sustainability.

Future procurement should prioritize units with documented service history and recent clutch or transmission overhauls to minimize downtime.
