The Dongfeng Liuqi Chenglong H7 400HP 8X4 7.6m LNG Dump Truck is a game-changer for operators needing heavy hauling power without diesel emissions—perfect for natural gas-mandated industrial parks, intercity road widening projects with strict carbon rules, or hauling gravel to large "green" residential developments. Powered by a Weichai WP13NG400E62 LNG engine, it delivers 400 horsepower and a robust 1900 N·m of torque at 1200-1800 rpm—enough to pull 20-ton loads up 17° slopes (common on intercity bypasses) without lag, while emitting 30% less CO₂ than comparable diesel trucks. Paired with a Fast 12JSD200TA 12-speed manual transmission, it shifts smoothly between 65km/h highway cruising and slow, precise movement on construction site gravel paths. The 8X4 drive setup and 5.73 rear axle ratio ensure steady traction, even when hauling wet sand or concrete—critical for avoiding delays in unpredictable weather.​

What makes this LNG model stand out for regional work is its 7.6m×2.4m×1.55m dump body, engineered to balance capacity and eco-efficiency. Built from Q690 high-strength wear-resistant steel, the body resists dents from sharp construction debris and features a lightweight design that offsets the LNG tank’s weight—keeping overall fuel efficiency high. With a Gross Vehicle Weight (GVW) of 31 tons and a rated payload of 19.2 tons, it can haul enough asphalt for 300 meters of highway repair in one trip, cutting down on round trips (and emissions) compared to smaller trucks. The hydraulic lifting system raises a full load in 27 seconds, while a reinforced double-layer frame (290×82×(13+11)mm) and 12/12/14-leaf spring suspension absorb bumps from uneven rural roads—protecting both the cargo and the LNG system during daily use.​

For fleet managers focused on sustainability and long-term cost savings, the Chenglong H7 LNG model delivers unmatched value. Its 1,000L LNG tank offers a 450+ km range—enough for round trips between neighboring cities without refueling—and LNG costs 20-25% less than diesel in most regions, slashing monthly fuel bills. Maintenance is simpler too: LNG engines have fewer moving parts than diesel counterparts, requiring oil changes only every 15,000km and reducing repair costs by 15%. Inside the cab, driver comfort supports long regional shifts: an air-suspended seat with heating/cooling, a 10-inch touchscreen with LNG level monitoring and reverse camera (for tight construction yards), and Bluetooth connectivity for hands-free calls. It’s the eco-friendly, cost-effective solution for heavy regional infrastructure—without sacrificing power or reliability.
