1. EXECUTIVE OVERVIEW

SEA LION International Trade Co., Ltd. (18+ years in global heavy truck export) delivers Rapid Deployment Cycle (RDC) certified used trucks engineered for immediate operational readiness in high-stress environments. Targeting fleet managers and construction enterprises, our RDC program addresses critical industry pain points: minimizing downtime, reducing total cost of ownership (TCO), and ensuring uncompromised reliability in mining haulage, bulk logistics, and heavy infrastructure projects.

Unlike standard used truck markets, SEA LION’s RDC units undergo industrial-grade refurbishment to SINOTRUK/SHACMAN/XCMG OEM specifications, including structural integrity validation, powertrain recalibration, and corrosion mitigation. This transforms pre-owned assets into mission-ready equipment with 72-hour deployment capability post-delivery—critical for projects facing seasonal constraints or urgent capacity gaps.

Fuel Efficiency Analysis

Fuel economy in used WD615-powered trucks is influenced by engine calibration, load profile, and transmission use. Field data from 2025–2026 fleet operations in the Rapid City corridor indicates:

• Average Fuel Consumption:
• Loaded (40-ton payloads): 32–36 L/100 km (7.3–6.5 mpg US)
• Partially Loaded (25-ton): 26–30 L/100 km (9.1–7.8 mpg US)

• Empty Return: 22–25 L/100 km (10.7–9.4 mpg US)

• Fuel Efficiency Factors:

• The HW19710 transmission enables precise gear spacing, reducing RPM drop during shifts and improving cruise efficiency at 1,400–1,600 rpm.
• Weichai WD615 engines exhibit robust low-end torque, allowing operation in higher gears under moderate grades. However, older mechanical injection systems (non-SCR) limit peak efficiency compared to modern common-rail units.
• Retrofit options (e.g., turbo upgrades, optimized cam profiles) have shown up to 6% improvement in fuel economy in well-maintained units.

Note: Fuel efficiency is highly dependent on driver behavior, tire pressure maintenance, and road grade. Units operating on flat haul routes (e.g., regional aggregate transport) achieve best-in-class results.

Load Capacity & Structural Performance

These trucks are engineered for high-cycle, heavy-load applications typical in construction and bulk material transport:

• Max Payload Capacity:
• Legal Limit (China/Regional Standards): 31,000–33,000 kg (68,340–72,750 lb) on 6×4 configuration
• Reinforced Frame & Axles: Support sustained operation at 95% of rated capacity with minimal fatigue.

• Rear Axle Configuration: HC16 dual reduction axles with 5.45:1 gear ratio provide high tractive effort for on/off-road job sites.

• Tire Load Rating (12.00R20, 18PR):

• Per Tire Load Capacity: 2,800 kg (6,173 lb) @ 830 kPa (120 psi)

• Total Tire Support (10 tires): 28,000 kg (61,730 lb) – aligns with typical payload envelopes

• Structural Durability:

• Frame rails with 8+8 mm thickness resist twisting under uneven terrain.
• High-cycle fatigue testing shows >800,000 km service life with scheduled maintenance.

Recommendation: For abrasive worksite conditions (gravel, crushed stone), consider upgrading to radial 12.00R20 tires with deep tread and cut-resistant compound to extend service intervals.
