The JAC Refine A3 Heavy Duty 375HP 8X4 8m Dump Truck is engineered to tackle the most demanding bulk hauling tasks in regional construction and logistics—whether you’re moving 25 tons of crushed limestone for a 10km highway expansion, transporting topsoil for a 500-acre agricultural development, or clearing debris from a downtown urban renewal site with multiple demolished buildings. Powered by a Weichai WP12.375E62 diesel engine, it delivers 375 horsepower and 1500 N·m of torque at 1200-1800 rpm—enough to climb 16° slopes (common on quarry access roads) with a full load, while maintaining steady power for 100+ km one-way hauls. Paired with a Fast 12JSD200TA 12-speed manual transmission, it shifts smoothly between 65km/h provincial highways (to meet daily bulk quotas) and slow, controlled movement on uneven construction site terrain. The 8X4 drive setup and 5.286 rear axle ratio distribute weight evenly across all rear wheels, preventing wheel spin on loose gravel or muddy earth—eliminating costly delays from stuck vehicles during high-volume operations.​

What sets this model apart for bulk hauling is its 8m×2.5m×1.6m dump body—one of the longest in its class—engineered for maximum volume without sacrificing maneuverability. Constructed from Q960 ultra-high-strength steel (with a 550HB wear resistance rating), the body withstands daily impacts from sharp aggregates and heavy debris without warping, while its extended length reduces round trips by 30% compared to 6m dump trucks. The hydraulic lifting system uses a dual-cylinder, high-pressure setup to raise the 8m-long body evenly—critical for preventing cargo shift when hauling loose materials like sand or topsoil—and lifts a full load in 28 seconds, fast enough to keep up with continuous quarry-to-job-site rotations. Underneath, a heavy-duty double-layer frame (320×90×(16+14)mm) and 14/14/18-leaf spring suspension absorb shocks from rough regional roads, protecting both the cargo and the truck’s chassis during years of heavy use. It also includes a reinforced front bumper and skid plates for the engine and fuel tank, adding extra protection against debris on construction sites.​

For large fleet managers focused on bulk efficiency and long-term ROI, the Refine A3 delivers tangible value. Its 500L fuel tank covers 400+ km per fill—enough for 2-3 round trips between a quarry and a 80km-distant highway project—while the Weichai engine’s intelligent fuel injection system keeps average consumption at 34-36L per 100km, 5% lower than comparable 375HP 8X4 dump trucks. Maintenance is streamlined for high-volume use: the engine uses 20,000km long-life oil, the transmission requires service only every 35,000km, and brake pads are coated with a ceramic wear-resistant material (lasting 90,000km even in dusty quarry conditions). Inside the cab, driver comfort supports 10+ hour bulk haul shifts: an air-suspended seat with heating and cooling (for extreme regional temperatures), a 12-inch touchscreen with offline navigation (for remote construction areas) and 360° surround-view camera (for tight quarry loading bays), plus ample storage for tools and personal items. It’s the rugged, high-capacity workhorse that keeps large-scale regional bulk hauling efficient and profitable—without compromising on power or durability.​
