Nigerian Clients Inspect Haohan 8x4 U-Shaped Dump Truck

AORUN | 2026-6-2

At Aorun’s digitized final assembly workshop and outdoor high-inclination test track, customers witnessed firsthand the seamless integration of the Haohan chassis’s heavy-duty, rigid mechanical structure with Aorun’s specialized U-shaped cargo body craftsmanship. They highly praised the technical redundancy demonstrated by "Made in China" products in meeting the demands of complex transport conditions in West Africa.

The Hohan 8x4 heavy-duty U-shaped Truck--Tipper-Truck----The-Ultimate-Solution-for-Heavy-Duty-Engineering---Mining.html" >dump truck features an 8x4 drive configuration (dual steer axles at the front, dual drive axles at the rear), scientifically distributing the weight of tens of tons of bulk cargo across its 12 mining-grade steel-belted tires. This design not only perfectly complies with the Federal Roads Agency of Nigeria's axle-load regulations for inter-state and inter-provincial trunk roads, but also significantly enhances the vehicle's traction coefficient on soft, muddy terrain during the rainy season—thereby completely eliminating the risk of wheel slippage and vehicle entrapment.

The interior of the U-shaped cargo body features a large-radius, smooth-curved transition, eliminating the sharp corners and dead zones characteristic of traditional square-box designs. When transporting highly viscous laterite, wet sand, or slag, materials slide smoothly down the curved side panels, enabling zero-residue unloading and significantly boosting the ton-kilometer efficiency of multi-cycle operations.

The entire cargo body is constructed from high-quality, wear-resistant steel plates, utilizing advanced CNC bending technology to minimize the number of longitudinal welds. While fully maintaining the body's resistance to impact and deformation, this design significantly optimizes the weight of the superstructure, thereby creating greater legal payload capacity and profit margins for the customer.

Aorun Modernized Preparation and Delivery Quality Inspection:

Continuous High-Angle Lifting Test: The vehicle is loaded with simulated counterweights, and multiple on-site tests involving maximum-limit 50° high-angle tipping are conducted. During these tests, the hydraulic system's pressure-holding integrity, the leak-free performance of the hydraulic cylinders, and the alignment of the U-shaped dump body upon return to its resting position are rigorously monitored.

Three-Layer Polyurethane Anti-Corrosion Coating: To address the typical tropical marine climate—characterized by extreme heat, humidity, and high salt-spray levels—found in coastal cities such as Lagos, Nigeria, Aorun employs a comprehensive shot-blasting rust removal process and applies high-quality anti-corrosion topcoats to the entire vehicle.

Long-Distance Maritime Wax Protection: The Sales Manager demonstrated to the client the heavy-duty anti-corrosion wax coating applied to the vehicle's chassis, pneumatic brake lines, and main valve box prior to shipment to the port. This protective waxing ensures that the vehicle remains safeguarded against electrochemical corrosion caused by marine salt spray during its transoceanic voyage.
