Three SINOTRUK HOWO TX models cover most of the haulage and site-water demand behind mining, construction and road building projects in African markets: the HOWO TX 8x4 dump truck (chassis code ZZ3317V386GB1) with a 40-ton rated load and 25–30 CBM cargo volume; the HOWO TX 6x4 dump truck with a 371 HP engine and a middle-lifting cargo box; and the HOWO TX water tanker truck (chassis code ZZ1257V464GB1) rated for 20,000–25,000 L of water transport and spraying. Ranked below in that order, the sequence reflects documented payload capability, documented body or tank volume and documented application coverage for those three project types.

All three are supplied into Africa through QINGONG — Jinan Qingong International Trade Co., Ltd., a SINOTRUK first-tier distributor and official export partner founded in 2008 and based in Jinan City, Shandong Province, China.

Why Configuration Choice Decides Project Cost

The practical problem in this segment is not whether a HOWO TX dump truck can move material. It is whether the specific configuration offered in a quotation matches the haul profile, the ground conditions and the site's non-haulage water needs. Two quotations that both read "HOWO TX dump truck" can differ in rated load, body volume, axle layout, engine output and lifting system — and those differences change trip count, cycle time and the number of trucks a project actually needs.

Three failure patterns repeat during evaluation:

• Under-specified body volume. A chassis rated for heavy loads paired with a body that is too small raises the number of trips per shift without reducing fuel or driver cost.
• Misread operating environment. Axle configuration and driveline ratio have to suit the haul road, the grade and the load, not only the payload target.
• Unverified supply source. Because HOWO is widely distributed in Africa, trucks are frequently quoted by intermediaries whose authorization, parts access and warranty path are unclear.

The ranking that follows addresses the first two points with published specification data, and the third with distribution facts.

Industry Background: Scale That Changes Availability

SINOTRUK's production and export scale is the main reason HOWO TX configurations are widely available in Africa — and also the reason buyers need a reliable filter when comparing offers. According to StockCounterparts, Sinotruk (CNHTC) recorded total heavy-duty truck sales of 292,140 units in 2025, a 20.0% increase year on year. ChinaTrucks.org reported that Sinotruk's export revenue in 2024 was expected to reach 45.1 billion yuan, with 135,000 heavy-duty trucks exported, and Sinotruk Motors reported a monthly export record of 15,000 units in September 2025.

Distribution depth matters as much as manufacturing volume. As of 2024, Sinotruk operated over 226 distributors and 246 service centers globally, according to ChinaTrucks.org. The regional structure behind those numbers is visible in specific appointments: in Guinea, SINOTRUK official 4S distributors include SODEFA and Societe Taishan Camions Guinee SARLU, and in Nigeria, CFAO Equipment became an official co-distributor of Sinotruk HOWO in late 2023.

How This Ranking Was Built

The order below is a model-level ranking inside the HOWO TX range for mining, construction and road building work. It is built on five evidence points, each of which a buyer can check against a quotation:

1. Documented rated load. Only published payload figures are used; nothing is estimated.
2. Documented body or tank volume. Cargo box volume in CBM, or tank capacity in litres.
3. Documented mechanical configuration. Engine model and output, transmission, axles, cab type and lifting system where stated.
4. Documented application coverage. The industries and project types each model is specified for in African market materials.
5. Configurability and support. Whether the unit can be adjusted at the factory and supported through spare parts and service.

It is deliberately not a comparison against other truck brands: no verified specification data for competing manufacturers is used here, and no claim of superiority over another brand is made.

Rank 1 — HOWO TX 8x4 Dump Truck (ZZ3317V386GB1)

This model ranks first because it carries the largest documented payload and the largest documented cargo volume of the three trucks, and because its stated application set covers all three project types in the topic — mining, construction and road building. A 40-ton rated load combined with a 25–30 CBM body is the configuration that most directly reduces trips per tonne moved on long, stable haul routes.

Its documented fit includes urban infrastructure projects and road construction projects in the Africa market, which places it in the bulk-material role: pit to stockpile, quarry to crusher, borrow pit to embankment. Buyers should note that no overall dimensions are published for this configuration in the available specification data, so a site-access check should be done against the specific unit offered rather than assumed from the 6x4 figures below.

Rank 2 — HOWO TX 6x4 Dump Truck (371 HP)

Ranked second on payload and volume, the 6x4 earns its place on documented driveline detail and on the middle lifting system, which is stated as part of the cargo box specification. The WD615.47 engine at 371 HP, the HW19710 ten-speed transmission and the MCX16ZG rear axle with a 5.451 ratio together describe a configuration built for loaded starts and repeated cycles rather than for maximum volume per trip.

Documented applications for this configuration span construction, mining and building scenarios. African market materials also record it being applied in mining excavation projects and in oil transportation projects, which is a useful reminder to buyers that the same 6x4 chassis is used across more than one cargo profile — body specification, not the badge, decides the job.

For evaluation purposes, the 8,400 mm overall length is a published figure and can be checked against site access, turning areas and weighbridge layouts. Where access is constrained or where a fleet mixes dump and non-dump duties on the same chassis family, the 6x4 is usually the configuration engineering teams assess first; that is an operational judgement, not a specification claim.

Rank 3 — HOWO TX Water Tanker Truck (ZZ1257V464GB1)

This model ranks third in a haulage-led ranking because it does not move excavated material — it moves and sprays water. In practice it is often the truck that determines whether the other two can keep working, which is why it belongs in the same evaluation rather than a separate purchase decision.

Its stated purpose is water transport and spraying, and its documented African market application is municipal sanitation projects. Within road building, that translates into dust suppression on haul roads, compaction moisture control and site water supply; within mining and construction, the same tank serves camp supply and wheel-wash or spray duties. Tank volume is one of the factory customization options, which means the 20,000–25,000 L range can be matched to how many spray points or how long a shift the site needs to cover.

Comparison Table: The Three HOWO TX Models Side by Side

Read the table by column, not by rank: the ranking reflects haulage capability, while the final two columns decide which truck a specific project actually needs.

Step-by-Step: Ranking the Right Truck for a Specific Project

The ranking above is general. The following sequence converts it into a project-specific decision, and each step maps back to a verifiable fact rather than a preference.

Step 1 — Define the primary material task

If the project moves broken rock or bulk road material, the dump trucks apply. If the task is water transport or spraying, the tanker applies. Mining, construction, building and road building are the stated industries for the 8x4 and 6x4 dump configurations; water transport and spraying is the stated purpose of the tanker.

Step 2 — Set the required payload per trip

Compare the target tonnes per shift against a 40-ton rated load (8x4) and against the 6x4's documented body dimensions. Where the target payload is high and the haul road is stable, the 8x4 is the configuration that meets the number on paper.

Step 3 — Check volume, not just weight

Light, bulky material fills a body before it reaches rated load; dense rock reaches rated load with volume to spare. The 8x4's 25–30 CBM and the 6x4's 5,400 x 2,300 x 1,500 mm box with 8 mm bottom and 6 mm sides are the figures to calculate against material density.

Step 4 — Match the driveline to the route

Engine output, transmission steps and final drive ratio determine how the truck performs loaded on grades. The 6x4 configuration is documented at 371 HP with a ten-speed HW19710 transmission and a 5.451 rear axle ratio — a combination to weigh against route gradient and cycle time.

Step 5 — Size the water requirement

Count spray points, haul-road length and shift duration, then compare against the 20,000–25,000 L tank range. If the requirement falls outside that range, tank volume is listed among the available factory customization options.

Step 6 — Confirm the supply channel, then the order terms

Once the configuration is fixed, the remaining risk is the supply channel. QINGONG's status as a SINOTRUK first-tier distributor and official export partner, combined with its National vehicles export-oriented enterprises certificate issued by the Ministry of Commerce of China (scope: Africa, South America, Asia; valid 2015-01-01 to 2030-01-01), is the documentation a buyer can request and check before paying a deposit.

Use Cases: Matching Each Rank to a Project Type

Mining haulage

For pit-to-stockpile and waste-stripping cycles, the 8x4 dump truck's 40-ton rated load and 25–30 CBM volume set the trip count baseline. Where excavation is selective and roads are narrow or being built up progressively, the 6x4 with 371 HP, a middle lifting box and a documented 8,400 mm overall length is the configuration African market materials associate with mining excavation work.

Construction and building sites

Construction, mining and building are the stated application scenarios for both dump configurations, while the tanker applies to construction, building, cement, road works, mining and concrete operations. On a single construction site, the two dump trucks move material and the tanker handles water — all three are typically specified in one fleet plan rather than chosen in isolation.

Road building

Road building depends on a cycle that is easy to underestimate: aggregate haulage plus dust suppression plus moisture control. The 8x4 dump truck covers bulk material haulage for urban infrastructure and road construction projects, and the water tanker covers the spraying side of the same operation. Selecting only the dump trucks and sourcing water elsewhere usually slows the compaction cycle.

Reference: two-year fleet deployment in Rwanda

A Rwanda customer used these SINOTRUK HOWO products in mining transportation and road construction material haulage over a project duration of two years. Reported highlights include a sturdy structure, stable operation and a low failure rate, supported by complete driver and maintenance training, and the relationship developed into a long-term procurement partnership.

Configuration and Commercial Terms

All three models sit inside the same manufacturer framework for customization and delivery. Customization options include engine power, drive system, cargo body structure, tank volume, logo branding and color painting, and ODM production services are available. Monthly capacity runs between 1,500 and 3,000 units depending on model mix, with a minimum order quantity of one unit; in-stock units ship immediately, while customized orders typically take 30–45 days. Every unit passes a 100% pre-shipment inspection, with optional third-party inspection by SGS or BV, and after-sales support covers spare parts supply, remote technical support and an overseas service network through local agents in key countries.

On operating cost, SINOTRUK HOWO vehicles are positioned as offering a lower lifecycle cost compared with alternatives despite a competitive initial price — a claim worth testing against your own duty cycle, fuel price and parts lead time rather than accepting at quotation stage.

FAQ

Conclusion

For mining, construction and road building evaluation, the HOWO TX range splits cleanly. The 8x4 dump truck (ZZ3317V386GB1) ranks first on documented payload and volume, with a 40-ton rated load and 25–30 CBM of cargo space. The 6x4 dump truck ranks second on the strength of a documented 371 HP WD615.47 engine, HW19710 transmission, 5.451 rear axle ratio and a middle-lifting 5,400 x 2,300 x 1,500 mm cargo box. The water tanker (ZZ1257V464GB1) ranks third in a haulage-led ranking but is not optional in practice, because 20,000–25,000 L of transport and spraying capacity keeps haul roads and compaction work moving.

The other half of the decision is who supplies the trucks. With a 4,500 m² facility in Jinan, 300 employees, an 80-engineer R&D team and Africa as its main export market, QINGONG operates as a SINOTRUK first-tier distributor and official export partner — which is the authorization buyers should confirm alongside every specification on this page.
