The JAC Refine K5W Heavy Duty 350HP 8X4 6.8m Dump Truck is engineered to tackle the most demanding regional heavy-haul tasks—whether you’re moving 18 tons of gravel for a highway subgrade project, transporting iron ore from a small mine to a nearby processing plant, or hauling excavated rock for an industrial park’s foundation excavation. Powered by a Weichai WP10H350E62 diesel engine, it delivers 350 horsepower and 1400 N·m of torque at 1200-1800 rpm—enough to climb 16° slopes (common on mine access roads) with a full load, while maintaining steady power for 80+ km one-way hauls. Paired with a Fast 12JSD160TA 12-speed manual transmission, it shifts smoothly between 65km/h provincial highways (to meet daily payload quotas) and slow, controlled movement on loose mine gravel. The 8X4 drive setup and 5.92 rear axle ratio are critical for traction: they distribute weight evenly across all rear wheels, preventing spin even when hauling wet ore or muddy earth—eliminating costly delays from stuck vehicles.​

What sets this heavy-duty model apart is its 6.8m×2.4m×1.5m dump body and industrial-grade design. The body is constructed from Q960 ultra-high-strength steel—40% more wear-resistant than Q690 steel—so it withstands daily impacts from sharp rocks and heavy aggregates without denting or cracking. Its reinforced tailgate features a double-locking mechanism to prevent leaks when hauling wet materials, and the hydraulic lifting system (powered by a high-pressure dual-pump setup) raises a full 18-ton load in just 20 seconds—fast enough to keep up with continuous mine-to-plant or quarry-to-job-site rotations. Underneath, a heavy-duty double-layer frame (300×85×(14+12)mm) and 13/13/16-leaf spring suspension absorb shocks from uneven mining roads or construction site terrain, protecting both the cargo and the truck’s chassis during years of heavy use. It also includes a skid plate for the engine and fuel tank, plus reinforced mud guards to shield critical components from debris.​

For large fleet managers focused on ROI and minimal downtime, the Refine K5W delivers unmatched value. Its 450L fuel tank covers 380+ km per fill—enough for 3-4 round trips between a mine and a 60km-distant processing plant—while the Weichai engine’s intelligent thermal management system keeps average fuel consumption at 32-34L per 100km, 6% lower than comparable 350HP 8X4 dump trucks. Maintenance is streamlined for heavy use: the engine uses 20,000km long-life oil, the transmission requires service only every 30,000km, and brake pads are coated with a wear-resistant alloy (lasting 80,000km even in dusty mine conditions). Inside the cab, driver comfort supports 10+ hour shifts: an air-suspended seat with heating and cooling (for extreme mine or highway temperatures), a 10-inch touchscreen with offline navigation (for remote mining areas) and 360° surround-view camera (for tight loading bays), plus ample storage for tools and personal items. It’s the rugged, high-capacity workhorse that keeps large-scale regional infrastructure and mining-adjacent projects on schedule—without compromising on power or durability.​
