Advantages of Howo NX 371HP 6X4 Tractor Head
Proven WD615 371HP Engine Core: Powered by the ultra-reliable, field-tested Sinotruk WD615 series turbocharged diesel engine. The 371HP output provides high low-end torque, simple mechanical maintenance, and exceptional tolerance to varying fuel qualities globally.
Classic HW transmission Matrix: Paired with a heavy-duty Sinotruk HW series 10-speed manual transmission, featuring a dual countershaft layout. This setup provides smooth gear shifting, high torque handling capability, and a long gear life under heavy payloads.
Reinforced Heavy-Duty Driving Axles: Equipped with military-grade HC16 or ST16 double-reduction rear axles engineered for high-load capacity. Built-in inter-wheel and inter-axle differential locks guarantee maximum traction on unpaved construction sites or slippery, muddy trails.
Upgraded NX Ergonomic Cabin Shell: The interior is built for operator stamina, featuring an air-ride suspension driver’s seat, a wrap-around multi-function dashboard, automatic climate control A/C, and an extra-wide integrated berth to minimize long-distance driving fatigue.
Lightweight High-Tensile Chassis Steel: The frame is constructed using advanced high-tensile steel pressings, reducing the chassis weight without compromising structural rigidity. This allows fleet managers to legally carry more cargo per trip.
Advanced Multi-Layer Electro-Phoretic Coating: The entire cabin structure undergoes automated multi-stage painting and protective primer dipping, protecting your truck from rust and structural corrosion in coastal ports or humid tropical environments.

Applications
The Howo NX 371HP 6X4 prime mover is a highly versatile workhorse across diverse industrial supply chains:
Heavy Aggregate & Mining Hauling: Routinely couples with 3-axle dump semi-trailers to transport sand, stones, minerals, and loose construction aggregates over harsh job site paths.
Liquid Fuel & Chemical Transport: The optimized chassis stability and reliable air brake networks make it the safest choice for pulling 40,000L to 45,000L carbon steel or stainless steel fuel tanker trailers.
Intermodal Container Shipping: Easily handles daily port shuttle duties, transferring heavy 20ft and 40ft shipping containers from ocean docks to inland logistics warehouses.
Equipment & Structural Moving: Provides the necessary low-gear torque to pull lowbed or drop-deck trailers loaded with small-to-medium excavators, wheel loaders, and manufacturing machinery components.

FAQ
Q1: What are the main benefits of choosing the Howo NX series over older Howo 7 models?
The Howo NX features an optimised lightweight frame design that lowers the chassis deadweight by several hundred kilograms, allowing you to load more payload while remaining under legal weight limits. Additionally, the cabin features improved aerodynamics, which can reduce highway fuel consumption by 3-5%, along with upgraded driver comfort structures.
Q2: Can this 371HP prime mover handle heavy dump semi-trailers in mining zones?
Yes, it is ideal for that application. When configured with the ST16 or HC16 16-ton double reduction rear axles and heavy-duty 12.00R20 steel wire tyres, the Howo NX 371HP delivers massive low-gear tractive force to pull fully loaded 30-to-40-ton dump trailers out of steep or muddy mining pits.
Q3: How do we get original spare parts if our company operates in remote construction sites?
We offer continuous, lifetime accessories support for every asset sold. We maintain a large inventory of original Sinotruk engine components, HW gearbox components, brake linings, and filters. Orders are packed and shipped via international air express directly to your regional base to ensure minimum fleet downtime.
