Detailed Description
The HOWO 420HP Prime Mover is engineered for demanding long-haul and heavy-duty applications. Powered by the proven D12.42 diesel engine, this prime mover delivers 420HP with substantial low-end torque, enabling confident starts under load and efficient cruising on mixed terrain. Built by trusted manufacturing partners in Shandong and distributed under the zw trailer channel, the vehicle is offered at factory-direct value with short lead times and complimentary accessories to simplify fleet onboarding.
Powertrain & Performance
At the heart of the vehicle, the D12.42 engine combines large displacement and modern fuel delivery to produce reliable power without excessive revving. The HW19712 transmission provides a broad ratio spread for hauling heavy loads while maintaining fuel economy. With a rated torque of 1900 N·m, the truck excels in both highway transport and moderate off-road conditions. The robust steering system (ZF8198) with power assistance ensures predictable handling even with full payloads.
Durability & Serviceability
The chassis and axle choices (HF7/HF9 front; ST16/HC16 rear) are selected to endure high-cycle operations and abrasive environments. An electric lifting system on the cab reduces maintenance effort and improves access to powertrain components for routine inspections. Factory direct sales and streamlined supply capabilities mean parts and support are accessible, reducing downtime for fleet operators.
Driver Comfort & Ergonomics
The HOWO tractor cab adopts a European-style layout with a wide windshield for enhanced visibility and reduced driver fatigue. The four-point fully floating cab isolates vibration, delivering a comfortable ride across long shifts. Practical features like electrically adjustable and heated rearview mirrors simplify operation in inclement weather while an ergonomic control layout keeps critical functions within easy reach.
