The Dongfeng Liuqi Chenglong H7 520HP 8X4 8.6m Dump Truck is built to tackle the toughest heavy-haul tasks—whether you’re pulling 25+ tons of iron ore up 20° mountain mine roads, delivering precast concrete segments for a 100km highway project, or hauling bulk aggregate for a hydropower dam. At its core is a Yuchai YC6K520-60 diesel engine, cranking out 520 horsepower and a massive 2500 N·m of torque at 1200-1800 rpm. This low-end torque is a game-changer for extreme conditions: it climbs steep mine grades without overheating and maintains steady power on 200+ km hauls, while pairing seamlessly with a Fast 12JSD240TA 12-speed manual transmission. The 12 gears let you fine-tune speed for everything from slow, controlled movement on loose mine gravel to efficient cruising at 70km/h on intercity highways, and the 8X4 drive setup + 5.92 rear axle ratio delivers unshakable traction—even when hauling wet ore or muddy construction materials.
What makes this model ideal for heavy-duty work is its 8.6m×2.45m×1.6m dump body—engineered for maximum capacity and durability. Constructed from Q960 ultra-high-strength steel (30% thicker than standard heavy-duty grades), the body resists deep scratches from sharp rock and corrosion from mine chemicals, while its reinforced hydraulic lifting system raises a full 24-ton load in just 25 seconds—critical for keeping mining or dam construction schedules on track. With a Gross Vehicle Weight (GVW) of 31 tons and a rated payload of 22.5 tons, it cuts down on round trips (often by 30% compared to smaller 7m trucks) when moving bulk materials. Underneath, a double-layer frame (300×85×(14+12)mm) and heavy-duty 13/13/16-leaf spring suspension with shock absorbers absorb impacts from uneven mine terrain, protecting both the cargo and the truck’s chassis during years of high-stress use.
For fleet managers focused on long-term reliability and cost-efficiency, the Chenglong H7 520HP delivers unmatched value. Its 550L fuel tank offers a 500+ km range—enough for round trips between remote mines and processing plants without refueling—and the Yuchai engine’s intelligent thermal management system keeps average fuel consumption at 35-38L per 100km, 5% lower than comparable 500+ HP mining trucks. Maintenance is streamlined for harsh environments too: the engine uses 20,000km long-life oil, the transmission requires service only every 30,000km, and brake pads are coated with wear-resistant alloy (lasting 80,000km even in dusty mine conditions). Inside the cab, driver comfort is prioritized for 10+ hour shifts: an air-suspended seat with heating/cooling (for extreme mine temperatures), a 12-inch touchscreen with offline navigation (for remote areas), and a 360° surround-view camera + tire pressure monitoring (TPMS) (critical for safety on narrow mine roads). It’s the industrial-grade workhorse that keeps heavy mining and mega-infrastructure projects moving.
