Two months ago, a Cameroonian municipal engineering contractor contacted our business team through our official website, requesting the purchase of three SINOTRUK HOWO 6X4 371HP Dump Trucks for the expansion of the Yaoundé-Douala Highway Phase II and the municipal network along the route. To meet their heavy-duty earthmoving needs, we discussed and customized a configuration plan with the client. The client quickly signed the contract and completed the payment smoothly, and the trucks were immediately put into production.
In this project, the trucks faced three major challenges posed by extremely demanding operating conditions. The first was the challenge to the air intake system: construction during the dry season generated vast quantities of fine red dust, which posed a severe risk of accelerated engine wear. Secondly, the driving environment is harsh, with scorching sun and high temperatures on bumpy dirt roads, which can easily cause driver fatigue during long hours of operation. Finally, there was the challenge of violent loading and unloading impacts; heavy-duty excavators on-site frequently dumped large rocks and heavy aggregates from significant heights, subjecting the upper edges and side panels of conventional cargo boxes to devastating physical blows.
Our customized HOWO TX demonstrates exceptional adaptability. To contend with pervasive red dust, the vehicle is equipped with an optional “engineering-grade” oil-bath air filter; this system efficiently captures impurities and, when paired with a highly robust 371-horsepower mechanical-pump engine, completely eliminates the wear-and-tear issues typically caused by dust ingress. To address the challenges of high temperatures and rough terrain, the upgraded TX cab features air-suspension seats and a high-efficiency air conditioning system, providing the driver with a comfortable working environment and significantly reducing operational fatigue.
To withstand the rigors of aggressive excavator loading and the impact of heavy cargo, we have implemented heavy-duty reinforcements across both the chassis and the superstructure. The vehicle features an 8+8 double-layer frame and 16-ton dual rear axles, delivering unparalleled load-bearing capacity. The manganese steel cargo box is specifically fitted with “anti-impact reinforcement strips” along the upper edges of its side panels. It can absorb the impact of falling boulders and more effectively prevent “box expansion” deformation under heavy loads, ensuring the vehicle is sturdy and durable.
