Detailed Description 

Howo TX 6x4 Tractor Truck delivering 440 HP and a flat 1,900 Nm torque band between 1,200 and 1,500 rpm. This power curve provides strong, steady pulling force for off-the-line acceleration, sustained climbs and long-haul cruising. Paired with the HW19710 10-speed manual transmission and a robust 430 mm clutch, gear transitions are direct and durable under heavy loads. The 6x4 configuration ensures traction where it matters — offering optimized load distribution and driveability on uneven, wet or unpaved surfaces common to heavy haulage routes.

Chassis, Axles and Load Handling

Built around a high-strength steel ladder frame , the HOWO TX 6x4 Tractor Truck combines torsional rigidity with serviceability. Front HF9 forged steel axle rated at 9 tons and HC16 double reduction rear axles rated at 16 tons provide the mechanical backbone for stable handling and long-term durability. The reinforced rear axle and heavy-duty suspension system support GCWs up to 60 tons in practical operation, while the 16-ton fifth wheel load capacity enables heavy semitrailer pairings for containers and bulk carriers.

Advanced fuel injection technology and calibrated engine management reduce consumption by up to 12% versus older generations, lowering day-to-day fuel spend for fleet operators. The sizable 400 L aluminum alloy fuel tank provides extended range between refuels, reducing downtime on long corridors. Maintenance intervals are extended — oil changes can reach up to 100,000 km under recommended service schedules — which, combined with robust component choice, helps to minimize lifecycle operating costs and maximize vehicle uptime.

Driver-focused design reduces fatigue over long shifts. The cabin layout prioritizes visibility, intuitive control placement and adjustability. Multi-leaf rear suspension with stabilizer bar provides a controlled ride under uneven loads, while front leaf springs and shock absorbers balance steering precision with load-bearing needs. Standard safety systems and strong structural design deliver predictable handling under emergency maneuvers, which is essential for protecting cargo and personnel on busy freight lanes.
