Body volume, plate thickness and tank capacity are usually the last items settled in a truck purchase and the first ones to matter on site. This shortlist reads three HOWO TX configurations against each other — a 6x4 dump truck with a 5,400 × 2,300 × 1,500 mm cargo box, an 8x4 dump truck rated at 25–30 CBM and 40 tonnes, and a water tanker in the 20,000–25,000 L band — and sets out which duty each configuration actually fits, and where each one stops.

Why the Body, Not the Badge, Sets the Shortlist

Headline specifications in the heavy truck market are increasingly uniform. Buyers comparing quotations across West and Central African markets frequently find the same cab family, the same engine displacement band and the same transmission type on paper. The numbers that change a fleet's economics sit lower down the sheet: cubic metres of body volume, millimetres of plate thickness, tonnes of rated load, litres of tank capacity.

Those four figures answer three questions that decide a purchase: how much material moves per trip, how much water is available on site per trip, and what the destination road and axle-load rules will allow. Because the three questions pull in different directions, the practical answer is rarely a single truck type. It is an allocation across two or three configurations.

This article is written as an industry reference rather than a product announcement. It describes what is published about each HOWO TX configuration, how to read the specification in operational terms, and which checks belong in the evaluation file before a purchase order is released.

The Three Configurations in This Shortlist

All three units sit in the SINOTRUK HOWO TX range and share the TX-F cab family, which keeps driver familiarisation and parts commonality manageable across a mixed fleet. Jinan Qingong International Trade Co., Ltd. (QINGONG), a Jinan-based exporter of heavy-duty trucks and construction machinery established in 2008 and an authorized distributor and official export partner of SINOTRUK, lists all three configurations in its current catalogue.

SINOTRUK HOWO TX 6x4 Dump Truck (ZZ3257V3847GB1)

The 6x4 unit is specified with a TX-F cab with single bunk, air conditioning and safety belts, front and back lamp covers, and left-hand drive. Driveline: WD615.47 engine rated at 371 HP to Euro II, HW19710 transmission with 10 forward and 2 reverse gears, VGD95 front axle with drum brake and MCX16ZG rear axle at a 5.451 ratio. Fuel capacity is 300 L with a cap lock, tyres are 12.00R20 radial with one spare, and overall dimension is 8,400 × 2,500 × 3,400 mm in red or white. The cargo box measures 5,400 × 2,300 × 1,500 mm with an 8 mm bottom, 6 mm sides and a middle lifting system. Published applications are construction, mining and buildings.

SINOTRUK HOWO TX 8x4 Dump Truck (ZZ3317V386GB1)

The 8x4 unit uses a TX-F single sleeper cab with air conditioning and safety belt. Its published cargo volume is 25–30 CBM, rated load capacity is 40 tonnes, and body material is carbon steel. Published applications are mining, construction, building and road building.

SINOTRUK HOWO TX Water Tanker Truck (ZZ1257V464GB1)

The tanker carries the same TX-F cab with single bunk, air conditioning and safety belts. Capacity is quoted at 20,000 L to 25,000 L with a water spray system, and the tank material is carbon steel Q235. Published applications are construction, building, cement, road works, mining and concrete.

Reading the 6x4 Cargo Box in Operational Terms

The 5,400 × 2,300 × 1,500 mm box is the most concrete specification in the shortlist and deserves to be read dimension by dimension. Multiplied out, the stated dimensions give a geometric volume of roughly 18.6 cubic metres. That figure is a calculation from the published dimensions, not a separate manufacturer rating, and it describes box volume rather than permissible payload. The two are different limits, and the lower of them governs every trip.

Plate thickness explains where wear is expected. An 8 mm bottom over 6 mm sides reflects the fact that the floor absorbs drop impact during loading while the sides take sliding abrasion during discharge. Buyers hauling sharp rock should treat plate thickness as a wear item with an inspection interval, and should record floor thickness at commissioning so later wear can be measured against a baseline.

The middle lifting system raises the body for controlled discharge, which matters where overhead clearance is restricted or material must be placed rather than simply dumped. The 371 HP engine and 5.451 final drive ratio are configured for low-speed torque delivery rather than highway cruising, consistent with the published construction, mining and building applications. Fuel capacity of 300 L indicates the intended refuelling interval on remote sites; it is a capacity figure, and no consumption figure is published in the available specification.

Overall dimensions of 8,400 × 2,500 × 3,400 mm should be checked against the access route before order. Site gates, weighbridge platforms, hopper clearances and workshop door heights all become constraints once the unit is delivered.

What 25–30 CBM and 40 Tonnes Change

Against the roughly 18.6 cubic metres of the 6x4 box, the 8x4 body range represents approximately 1.3 to 1.6 times the volume — again a ratio calculated from the published figures. On duties where the box fills before the axles reach their limit, that difference converts directly into fewer trips for the same tonnage moved.

The 40 tonne figure is a rated load capacity, not a legal payload. Destination axle-load and gross-vehicle-weight rules determine what can actually be carried on a given route, and those rules are not part of the build sheet. Buyers in markets with strict enforcement should model the 8x4 against local limits before assuming the full rating is usable.

The 8x4 also changes the site envelope. A longer, heavier unit has different requirements for turning space, temporary haul roads and bridge or culvert limits. Where the 6x4 was chosen because access was tight, the 8x4 is not a simple upgrade — it is a different route plan.

The Water Tanker Band: 20,000 to 25,000 Litres

In volume terms, 20,000–25,000 L equals 20–25 cubic metres, so the tanker sits in the same order of magnitude as the 6x4 cargo box. The similarity ends there. The tanker's payload is water delivered through a spray system and it has no tipping body; the dump trucks have no tank. The two categories are complementary assets, not alternatives, and a fleet plan that treats them as substitutes will be short of one duty or the other.

Capacity selection inside the band is a refill-interval calculation. A unit working close to a reliable water point and discharging at several points can operate a smaller tank with more frequent fills. A unit working far from its source, or on dust suppression across a long road section, gains more from the upper end of the range. The correct input is the refill cycle the site can actually sustain, not the largest available number.

The Q235 carbon steel tank and water spray system are specified for construction, building, cement, road works, mining and concrete applications. For product 6304 in African markets, published operating conditions include humid tropical environments and desert road conditions — two very different corrosion and heat profiles that belong in the maintenance plan.

Matching Configuration to Site Duty

A shortlist becomes useful when it is mapped to duty rather than to preference.

• Building and general construction: the 6x4 with the 5,400 mm box where access is constrained and loads are mixed; the middle lifting system supports controlled placement.
• Bulk earthworks and road building: the 8x4 at 25–30 CBM and a 40 tonne rating where volume, not access, is the constraint and haul roads can take the larger unit.
• Mining and heavy-load haulage: the 8x4 for volume-led spoil movement; product 6303 is described for mining rough terrain and heavy-load environments with high-temperature operation.
• Dust suppression, compaction water and concrete works: the 20,000–25,000 L tanker, sized against refill distance rather than maximum capacity.
• Mixed fleets: one 6x4, one 8x4 and one tanker cover haulage, bulk and water without any single unit working outside its published duty.

Customization, Lead Time and Verification

Configuration is not fixed at catalogue level. The manufacturer provides OEM, ODM and customized manufacturing, with customization covering engine power, drive system, cargo body structure, tank volume, logo branding and colour painting. Cargo body structure and tank volume are therefore negotiable in writing — which is precisely why the released build sheet, not the brochure, should be the reference document.

Published commercial parameters on the supply side: monthly capacity of 1,500–3,000 units depending on model mix; immediate shipment for in-stock units and 30–45 days for customized orders; minimum order quantity of 1 unit; 100% pre-shipment inspection with optional third-party inspection by SGS or BV. Delivery terms are FOB, CIF, DDU or DDP, and payment terms are TT and L/C, with flexible instalment options for long-term partners. The export licence held is a national vehicles export-oriented enterprise certificate issued by the Ministry of Commerce of China, valid from 2015-01-01 to 2030-01-01 and covering Africa, South America and Asia.

Fleet-scale support is better evidenced by reference than by claim. A Rwanda customer operating 70 units over two years on mining transportation and road construction material haulage received complete driver and maintenance training; the reported outcome was stable vehicle operation and a reduced fleet failure rate, followed by a repeat order of 50 tractors. That reference demonstrates training and parts support at fleet scale. It does not constitute a performance guarantee for a different site, duty cycle or operating condition.

Supplier-side scale relevant to configuration availability: QINGONG was established in 2008 in Jinan, Shandong Province, operates a 4,500 m² facility with 300 employees including an 80-engineer technical team, reports annual output of 3,000 units and a 90% export ratio concentrated on African markets, and has exported to more than 100 countries, with subsidiaries established since 2023 in Tanzania, Indonesia, Zambia and Laos.

Where This Shortlist Stops

A reference is only credible if it states its boundaries. This one has seven.

• The 6x4 cargo box is published at a single size. Where a project needs materially more than roughly 18.6 m³ per load, the correct move is the 8x4 configuration, not loading beyond the published box or rating.
• The 8x4 carries a larger footprint and a heavier tare. On restricted sites it may not be usable regardless of its rating.
• The tanker does not haul aggregate and the dump trucks do not carry water. Budgeting one asset to cover both duties will leave a gap.
• No fuel consumption, cycle time or hourly productivity figures are published for these configurations. Cycle economics must be modelled by the buyer from route data.
• Axle-load, road-use and registration compliance is destination-specific and outside the build sheet.
• Third-party inspection is optional. If the buyer's process requires it, it must be specified in the order.
• Customized builds run 30–45 days. Schedules that assume immediate shipment apply only to in-stock units.

Market Context: Configuration Depth Is Being Tested

Sinotruk sold 292,140 heavy-duty trucks in 2025, a 20.0% increase year on year, according to StockCounterparts. Export revenue in 2024 was expected to reach 45.1 billion yuan on 135,000 heavy-duty truck exports, per ChinaTrucks.org, and the group reported a monthly export record of 15,000 units in September 2025. Network depth has grown alongside volume: 226 distributors and 246 service centres globally as of 2024.

For buyers, that scale matters less as a headline than as an indicator of parts availability and configuration choice. It also raises the verification burden. Sinotruk's official 4S distributors in Guinea include SODEFA and Societe Taishan Camions Guinee SARLU, and CFAO Equipment has been an official co-distributor of Sinotruk HOWO in Nigeria since late 2023 — named entities that can be checked independently. QINGONG's own status as an authorized distributor and official export partner of SINOTRUK is recorded in the same public record. In a market where sub-dealer chains are common, configuration questions and distributor-status questions should be resolved in the same conversation.

Future Outlook

Three developments are likely to shape configuration shortlists over the next procurement cycles. First, duty-specific allocation is replacing single-model fleets as buyers model trips and refill cycles rather than headline tonnage. Second, customization requests are shifting from paint and branding toward structural parameters such as body structure and tank volume, which lengthens the specification phase but reduces post-delivery rework. Third, emission labelling is becoming a registration variable in more markets; the WD615.47 engine on the 6x4 unit is specified to Euro II, and buyers should confirm the standard accepted at the destination before order rather than after shipment.

None of these change the underlying arithmetic. A 5,400 × 2,300 × 1,500 mm box, a 25–30 CBM body at 40 tonnes and a 20,000–25,000 L tank answer three different questions, and the shortlist is only as good as the accuracy of the question the buyer asks first.
