Key Benefits

What This Unit Does Well

  • HW19710 ten-speed gearbox provides usable ratios for loaded climbs and empty return runs
  • HF9 front and HC16 rear axles support 9000kg and 16000kg per axle respectively, ideal for 51-60 ton payloads
  • 12R22.5 tubeless tyres reduce downtime from punctures on rough terrain
  • 300L fuel tank supports long hauls between refuelling points in remote mining or construction zones
  • Air-suspended cab with four-point mounting reduces driver fatigue on extended off-road shifts
Application Scenarios

Where It Is Used

  • Coal transport from mine to rail transfer point on uneven, dusty terrain
  • Construction site material delivery where road conditions are poor and maintenance access is limited
  • Long-distance haulage between remote mining camps and processing plants with infrequent fuel stops
Fit

Who It Is For

  • Fleet owners replacing older dump trucks with a standardised engine and transmission across multiple units
  • Contractors needing a dump truck that shares parts with other HOWO A7 models already in use
  • Machinery dealers stocking dump trucks for resale in African and Middle Eastern markets
  • Government procurement teams sourcing heavy-duty vehicles for infrastructure projects with limited local support
Buyer Pain

Problems It Solves

  • Mixed fleets where every truck requires different clutch, axle, or filter part numbers
  • Downtime caused by parts that take weeks to arrive from Europe or North America
  • Trucks that lack sufficient axle capacity for heavy payloads, leading to overloading and safety risks
  • Cab vibration and driver fatigue on rough terrain due to rigid suspension systems
  • Fuel shortages on remote sites due to small tank capacity and inefficient engine performance
Engineering

Honest Comparison

How It Compares With the Alternatives

6x4 dump truckThe 8x4 provides better traction and load distribution on soft or uneven terrain but consumes more fuel when running empty
Smaller 300L fuel tank model300L tank supports longer hauls between refuelling points in remote operations, reducing downtime
Use Guide

Using It Well

  • Replace fuel and oil filters on the interval set for WD615 engines, not on a generic schedule
  • Keep the air dryer cartridge stocked, humid environments shorten its life
  • Order the clutch plate, injector set, and axle seals with the truck so the first service does not wait on shipping

Buyer Questions

Questions About This Unit

Is this unit new or used

New. All units are factory-new with zero hours and full warranty from the plant.

What is the lead time

Units in stock can be prepared and loaded within 10 days. A build to your specification depends on the plant schedule, so we confirm a date in writing with the proforma invoice.

Can you supply spare parts for this truck later

Yes. WD615 filters, injectors, clutch parts, axle components, and brake linings are the parts we ship most often and can be consolidated with the truck order.

Do you ship by container or RoRo

Dump trucks normally go RoRo. Container shipment is possible with the cab lowered, but RoRo is more cost-effective and safer for this model.

What documents do I get for customs

Commercial invoice, packing list, bill of lading, certificate of origin, and any pre-shipment inspection certificate your country requires.
