Used Sinotruk HOWO Nx / Shacman / FAW 371HP 400HP 6X4 Tractor Truck

The HOWO NX series is Sinotruk’s cost‑effective heavy‑duty tractor lineup, slotting between the premium TX7 and entry‑level N7 models. It offers robust powertrains from 380 hp to 400 hp, is available in both 6×4 and 4×2 drive configurations, and features standardized modular construction for improved reliability, comfort, and ease of maintenance.

Powertrain & Transmission

Equipped with Weichai’s WP12.400E201 six‑cylinder, 11.6 L diesel engine rated at 400 hp, the HOWO NX delivers strong low‑end torque and complies with Euro II emissions. A 10‑speed forward and 2‑speed reverse manual gearbox (model HW19710) ensures precise gear selection, while an optional 16‑speed automated transmission is offered on higher‑trim variants. ZF‑branded hydraulic power steering provides responsive handling, even under heavy loads.

Chassis, Axles & Suspension

Built on a ladder‑frame chassis with 300 × 80 × 8 mm parallel U‑profiles, the NX series features reinforced cold‑riveted cross members for enhanced rigidity. Front suspension uses ten‑leaf semi‑elliptic springs paired with hydraulic double‑action shock absorbers and a stabilizer bar; the rear employs twelve‑leaf springs and bogie‑style mounts for balanced load distribution. The front axle is rated at 9.5 t, while the rear tandem supports up to 16 t per axle, complete with hub‑reduction gearing and inter‑axle differential locks for traction in challenging terrain.

Cabin & Comfort

The H77L cab on the NX is a full‑floating design with dual berths, air suspension for the driver’s seat, and a rigid‑adjust co‑driver’s seat, all protected by safety belts. Standard amenities include air conditioning, a multi‑speed two‑arm windshield wiper system, an FM/AM/SW radio with four‑band reception, adjustable steering column, and ample overhead and side storage. The cabin’s modern dashboard features a large LCD instrument cluster and relay‑based controls for intuitive operation.

Brakes, Electrics & Supporting Systems

Braking is managed by a dual‑circuit air system with spring‑energized parking brakes on both axles and an exhaust‑type auxiliary brake for downhill control. The 24 V electrical system comprises a 5.4 kW starter, 28 V/1 500 W alternator, and two 12 V/165 Ah batteries. A single spare tyre (315/80 R22.5) is carried on‑board, and the 400 L fuel tank supports long‑distance hauls.

Dimensions & Capacity

With overall dimensions of approximately 6 850 mm in length, 2 496 mm in width, and 3 750 mm in height, the NX tractor accommodates a standard fifth‑wheel rated at 90 mm. Its wheelbase of 3 225 + 1 400 mm balances stability with maneuverability, while the vehicle’s kerb weight of around 8 000 kg allows for a gross combination mass suitable for most container and bulk haul applications.

Applications

Designed for long‑haul, container, and bulk transport, the HOWO NX tractor is popular in emerging markets across Africa, Southeast Asia, and Latin America. Its blend of power, simplicity, and low life‑cycle costs makes it an attractive choice for fleet operators seeking maximum uptime and return on investment.
