It integrates cargo loading, long-distance haulage and hydraulic automatic unloading functions, realizing one-stop engineering material transportation.
Equipped with industrial-grade reinforced chassis and professional mining-grade rear axles, the whole vehicle owns outstanding off-road performance. Matched with classic mechanical pump powertrain, it has strong fuel adaptability, perfectly fitting areas with low-quality diesel supply. With universal global spare parts supply and full-set export certifications, it becomes the most cost-effective engineering vehicle for emerging markets.
Product Core Functions & Advantages
1. Superior Load-bearing & High Transport Efficiency
The 6×4 dual rear drive axles structure delivers far stronger load-bearing capacity than 4×2 single rear axle. Its 25000kg GVW and large rated payload greatly improve transport efficiency for mine ore, earthwork and aggregate haulage.
2. Excellent Off-road Trafficability for Harsh Roads
Equipped with 16T wheel-reduction rear axles & inter-axle plus inter-wheel double differential locks, the rear eight-wheel tipper owns superior off-road trafficability. It easily passes muddy, bumpy mine roads where single axle trucks get stuck frequently.
3. Large-capacity Wear-resistant Cargo Body
The large-volume wear-resistant manganese steel tipper body with front hydraulic lifting cylinder realizes one-time high-volume unloading, cutting delivery times remarkably compared to small cargo box of single axle dump truck.
4. Low Long-term Operating Cost & Global Adaptability
With huge global market stock, universal spare parts and mature service network, the HOWO rear eight-wheel model maintains lower long-term operation cost. It is the mainstream heavy transport vehicle for Africa, Central Asia and Southeast Asia infrastructure projects, while single axle trucks only fit light-duty short-distance tasks.
5. Mature Powertrain & Easy Maintenance
This classic HOWO
6×4 Dump Truck is equipped with Weichai 371HP Euro II mechanical pump engine, delivering stronger low-speed torque than 340HP version for heavy climbing and tipping.

2. Working Principle
The whole operating system of HOWO 371HP 6×4 dump truck consists of five core linkage modules: chassis driving system, Weichai powertrain system, dual rear axle driving system, hydraulic unloading system and PTO power output system.
During material transportation, the Weichai 371HP mechanical pump engine outputs steady torque, matches with 10-speed heavy transmission to transmit power to 16T dual rear drive axles. Benefiting from inter-axle and inter-wheel double differential locks, driving torque can be evenly distributed to eight rear tires. When passing muddy or bumpy roads, the differential lock locks slipping wheels to enhance tire adhesion, preventing vehicle stalling and trapping.
After arriving at the unloading site, the driver activates the PTO device to transmit engine power to the front hydraulic lifting cylinder. The hydraulic system pushes the manganese steel cargo box to tilt upward stably, realizing gravity automatic unloading of ore, soil and aggregate. After unloading completes, the hydraulic cylinder resets the cargo box, and the whole vehicle returns to transportation status.
Different from electronic fuel-controlled engines, the pure mechanical fuel supply structure cuts electronic control components, avoiding shutdown failure caused by poor diesel quality. The balanced suspension buffers road vibration during full-load driving, protecting chassis and axle components and extending vehicle service life.
3. Daily Application Scenarios
Mining Resource Transportation: Open-pit mine ore haulage, coal yard bulk material transportation, quarry aggregate and gravel delivery
Civil Engineering Construction: Urban earthwork backfilling, road foundation construction, construction waste outward transportation
Infrastructure Projects: Highway embankment paving, water conservancy engineering, bridge foundation material transportation
Harbor & Logistics Haulage: Port bulk cargo transfer, yard gravel turnover, heavy building materials short-distance transit
Overseas Emerging Market Projects: Large-scale engineering bidding projects in Africa, Central Asia, Southeast Asia, adapting to local fuel and road conditions
4. Comparison with Traditional Vehicles
Vs 4×2 Single Rear Axle Dump Trucks: 4×2
Light Tippers own limited bearing capacity, weak off-road ability and small cargo volume, easy to be stuck on muddy mine roads. This 6×4 dual rear axle model has stronger load-bearing and anti-slip performance, larger single-shipment capacity, greatly boosting daily transportation output.
Vs 340HP Low-power HOWO Dumpers: The 340HP version has insufficient low-speed torque, difficult for heavy-load climbing and hydraulic unloading. This 371HP upgraded engine delivers stronger explosive torque, more suitable for heavy-load uphill and frequent unloading working conditions.
Vs Electronic Fuel-control Engineering Trucks: Electronic engine requires high-quality diesel and professional electronic maintenance, vulnerable to fuel impurity failure. This mechanical pump engine has simple structure, high fuel tolerance, no complicated electronic parts, lowering overseas maintenance difficulty.
Vs Refitted Assembled Dump Trucks: Modified tippers have mismatched axles and hydraulic systems, easy to cause cargo box rollover and oil leakage. This original factory HOWO vehicle adopts integrated matched assembly, coordinated overall performance, higher driving and unloading safety.
