The JAC Refine A3 Heavy Duty 245HP 8X4 6.8m Dump Truck is built for regional operators who need 8X4 stability for bulk loads—without paying for unused high horsepower. It excels at tasks like hauling 18 tons of construction sand to a suburban housing development’s foundation sites, delivering road base gravel for county road patching projects, or transporting agricultural mulch to large farm fields. Powered by a Yuchai YC6JA245-60 diesel engine, it delivers 245 horsepower and 950 N·m of torque at 1400-2000 rpm—enough to climb 12° rural slopes (common near sand quarries or farm access roads) with a full load, while avoiding the fuel waste of 300HP+ models. Paired with a Fast 10JSD140TA 10-speed manual transmission, it shifts smoothly between 58km/h regional roads (to meet daily delivery targets) and slow, controlled movement in small quarry yards or farm fields. The 8X4 drive setup and 5.73 rear axle ratio provide steady traction on loose gravel or wet farm soil, preventing wheel spin during loading/unloading—while its 6.2-meter turning radius keeps it agile enough for suburban neighborhood streets.​

What makes this model a cost-efficient choice is its 6.8m×2.4m×1.5m dump body and low-maintenance design, tailored for medium-bulk loads. Constructed from Q690 high-strength steel (durable enough for sand, gravel, or mulch, yet lighter than ultra-heavy Q960), the body balances capacity and weight to boost fuel efficiency—its 18-ton rated payload hits the sweet spot for small-to-mid contractors who don’t need 25-ton+ capacity. The hydraulic lifting system uses a single high-pressure pump (simpler and cheaper to maintain than dual-pump setups) to raise a full load in 25 seconds—fast enough for 5-6 daily runs, without the complexity of high-performance systems. Underneath, a reinforced single-layer frame (280×80×12mm) and 10/10/12-leaf spring suspension absorb shocks from rural roads and farm tracks, protecting the truck’s chassis during long-term use. It also features standard-size 11.00R20 tires and easily accessible engine components—local repair shops can service it without specialized tools, cutting maintenance wait times and costs.​

For budget-focused operators, the Refine A3 245HP delivers value at every step. Its 380L fuel tank covers 320+ km per fill—enough for 4-5 daily runs between a sand quarry and suburban job sites—while the Yuchai engine’s optimized combustion keeps average fuel consumption at 25-27L per 100km, 10% lower than the 375HP A3 variant. Maintenance costs are also reduced: the engine uses 15,000km long-life oil (longer intervals than entry-level models), and brake pads last 70,000km even with frequent farm/quarry use. Inside the cab, practicality meets comfort for all-day shifts: an air-suspended fabric seat (eases fatigue from rural road bumps), a 9-inch touchscreen with reverse camera (critical for backing into small quarry loading bays or farm gates), and basic climate control (simple to maintain and energy-efficient). It’s the no-frills, reliable workhorse that lets regional operators handle medium-bulk hauling—without overspending on power or features they don’t need.​
