HOWO TX 6x4 Dump Truck — 440HP MC11 Engine, LHD/RHD, CIF Export

What Makes the HOWO TX Different from a Standard HOWO Dump

Most buyers already know the standard howo dump truck — typically a 371HP WD615-powered unit that has proven itself on construction sites across Africa and the Middle East for over a decade. The TX is a step above that.

Two things set it apart:

• Premium TX cab. Wider, better insulated, more driver-friendly than the older A7 or T7H cab. On long hauls from a mine to a port — Lusaka to Dar es Salaam, or Kampala to Mombasa — driver fatigue matters. The TX cab reduces it.
• MC11.44-50 engine (440HP). This is not the WD615. The MC11 is a MAN-licensed six-cylinder in-line engine with higher displacement and a 440HP output. It produces more torque at lower RPM, which translates directly into pulling power on loaded climbs. Routes through Ethiopia, the DRC highlands, or mountainous terrain in Iraq and Oman reward this kind of engine.

If your routes are flat and short, the standard 371HP unit may do the job at lower cost. If your routes are long, loaded, and involve altitude or gradient — the HOWO TX 6x4 dump truck is the correct choice.

MC11 440HP Engine — Why It Matters for Heavy Haulage

The MC11.44-50 is built under MAN licence and shares engineering DNA with European truck engines. Key points for buyers:

• 440HP continuous output — not a peak figure that drops under load. The engine sustains power through long climbs.
• High torque at low RPM — keeps the truck moving without excessive downshifting on gradient roads, which reduces drivetrain wear.
• Parts supply growing. MC11 parts are now stocked by distributors in Nairobi, Lagos, Dubai, and Kampala. This is not a niche engine — it is used across HOWO's premium line and parts pipelines have matured accordingly.
• Euro III rated — accepted for import in most African and Middle East markets without additional emissions modification.

Compare this to the WD615 (371HP): the WD615 is reliable and parts are everywhere, but it was not designed for 440HP output. The MC11 is a larger, purpose-built unit at this power level. When you are running 40+ tonne payloads on a 6x4 platform, those 70 extra horsepower and the torque curve behind them make a real difference on gradient roads.

6x4 Platform and Transmission — Built for Loaded Conditions

The 6x4 dump truck configuration gives you two driven rear axles. On soft ground — quarry floors, unpaved mine access roads, laterite tracks in the wet season — the 6x4 keeps the truck moving where a 4x2 would spin out. It is the standard choice for heavy tipper work in sub-Saharan Africa and across the Gulf.

The HW25712XSJ 12-speed gearbox pairs well with the MC11's power band. Twelve ratios mean the driver can keep the engine in its torque range on descents as well as climbs — important for load control on mountain roads and for reducing brake wear over time. Tyre size is 12R22.5, a common fitment in the region. Replacements are available from importers in South Africa, Kenya, Nigeria, and the UAE without special ordering.

Refurbishment and Inspection — What We Do Before Export

Every unit we ship goes through a defined refurbishment process before it leaves China. This is not a wash-and-photograph operation.

• Engine inspection and service — oil, filters, belts, injectors checked and replaced to schedule.
• Drivetrain check — gearbox, differentials, prop shafts, hubs inspected for wear.
• Hydraulic system — the tipper ram, pump, and lines tested under load before sign-off.
• Brake system — air brake components, drums or discs, slack adjusters all checked.
• Cab and electrics — lights, gauges, wiring inspected; cab repaired where needed.
• Cargo box — floor plate thickness and side walls checked; welding repaired where required.

We provide a pre-shipment inspection report and photos for each unit. Third-party inspection (SGS, BV) can be arranged on request before loading.

LHD and RHD — Export to Africa and the Middle East

We convert in-house. Whether you need left-hand drive for markets like Nigeria, Ghana, DRC, Iraq, and the UAE — or right-hand drive for South Africa, Kenya, Uganda, Tanzania, and Zambia — we handle the conversion before shipment.

Shipping is CIF to your port of destination. We have shipped to Mombasa, Dar es Salaam, Durban, Lagos, Tema, Beira, Aqaba, and Jebel Ali, among others. We handle the export paperwork, bill of lading, and insurance. Your clearing agent receives the documentation package needed for customs at the destination port. If you are importing a used dump truck for the first time, or need to understand duty classification in your country, we can walk you through the HS codes and documentation that typically apply.

Buyer Checklist — What to Confirm Before You Order

Before committing to a unit, go through this list with us:

1. Year and mileage. We will provide the exact year of manufacture and odometer reading for the unit on offer. These vary — contact us for current stock.
2. Engine hours and service history. Where records exist, we share them. Where they do not, we document our own pre-export inspection findings.
3. Cargo box condition. Floor plate thickness and side wall integrity matter for quarry work. Ask for specific photos of the box interior.
4. LHD or RHD. Confirm your country's requirement before we quote conversion cost.
5. Port of destination. CIF pricing depends on the port. Give us your port and we quote CIF to that point.
6. Duty and import rules in your country. Age restrictions and emission standards vary. Confirm with your clearing agent before purchase.
7. Parts plan. Ask us or your local HOWO distributor about MC11 parts availability in your city before you commit. In most major markets it is not an issue, but confirm it for your specific location.
