Finalizes Deal for Sinotruk HOWO 6x4 Tractor Trucks

AORUN | 2026-8-7

Technical Engineering for the Cotonou Inland Transit Corridor

Managing cross-border freight from coastal Cotonou through dusty interior trade roads demands low-maintenance mechanics, high GCW load capacity, and robust cab comfort. During the Yiwu business meeting, our sales engineering group outlined key features tailored for Beninese hauliers:

1. Robust Euro II Mechanical Fuel-Injection Powertrain

• Equipped with the heavy-duty WD615 series 371hp / 380hp mechanical engine, these HOWO 6x4 prime movers perform smoothly despite variable diesel fuel quality across inland border stops, eliminating costly ECU sensor failures.

• Paired with a heavy-duty HW19710 10-speed manual gearbox with PTO, providing low-rpm high torque output on unpaved detour roads and steep inclines.

2. JOST Heavy Fifth Wheel & Double Reinforced Frame

• Stable Coupling: Outfitted with a high-strength JOST 2.0-inch or 3.5-inch cast steel fifth wheel plate, engineered to securely pull high-cube container trailers, flatbeds, and fuel tankers.

• Double-Layer Steel Frame: Built on an 8+8mm cold-riveted ladder chassis frame designed to absorb intense bending forces during max-GCW long-distance transit.

3. Coastal Anti-Corrosion & Long-Distance Cab Comfort

• Marine-Grade Painting: Complete chassis receives shot-blasting, multi-layer zinc-epoxy anti-rust primer, and topcoat protection to withstand high-salinity air around Cotonou Port.

• Extended Sleeper Cab: Features an ergonomic HW76/HW79 wide cabin with double berths, high-capacity air conditioning, and reinforced suspension to minimize driver fatigue on multi-day cross-border trips.
