In modern long-haul and regional logistics, complex electronics can often become a liability on unpaved roads or in areas with high-sulfur fuel. The China HOWO TX Euro 3 6x4 Trucks Tractor is engineered on a low-maintenance, high-torque platform that mechanics anywhere in the world can easily service. Whether you are hauling flatbed trailers, lowboys with heavy machinery, or bulk fuel tankers, this tractor unit provides steady traction and unbreakable chassis stability.

• Heavy-Duty Fifth Wheel : Fitted with a reinforced 50# (2-inch) or optional 90# (3.5-inch) cast steel fifth wheel plate mounted on a flexible subframe. It ensures a secure, wear-resistant connection with high articulation angle for smooth turning with loaded semi-trailers.
• Double-Layer Chassis Frame : Constructed with high-tensile steel cold-stamped frame rails (8+8mm thickness). This rigid structure prevents frame twist when pulling multi-ton trailers over uneven terrain or off-road job sites.
• Axles & Suspension : Features an HF9 (9-ton capacity) front steering axle and dual HC16 (16-ton capacity each) double-reduction rear drive axles with inter-axle differential locks. Backed by multi-leaf heavy-duty steel springs and thick U-bolts, it easily handles high pin loads from heavy trailer kingpins.
• Long-Range Fuel Capacity : Equipped with a lightweight, corrosion-resistant 400L aluminum alloy fuel tank that minimizes tare weight while giving drivers extended range between fuel stops.

Proven Euro 3 Mechanical Engine : At the heart of this tractor head is the heavy-duty WD615 / D12 series turbocharged intercooled diesel engine, producing 371 HP to 420 HP. The Euro 3 fuel system is extremely forgiving with local fuel qualities, ensuring easy cold starts, smooth idling, and high low-end torque for pulling away under full loads.

High Torque at Low RPM : Generates immense pulling power across a wide RPM band, making it easy to climb steep gradient roads, quarry ramps, or highway inclines without cooking the engine.

HW19710 Manual Gearbox : Paired with Sinotruk's classic 10-speed manual transmission (10 forward + 2 reverse). The wide gear ratio spread gives the operator precise control-low crawling gears for getting heavy trailers moving, and high overdrive gears for fuel-efficient highway cruising.

Heavy-Duty Cooling & Air Filtration : Features a high-capacity radiator and a dual-stage air intake filter system designed to protect the engine cylinders from heavy dust environments commonly found near mines and construction corridors.

MAN-Derived Cab Structure : The HOWO TX cab adopts European collision safety standards with a high-strength steel cage structure, offering superior impact protection and excellent sound insulation against engine noise.

Ergonomic Workstation : Designed with a driver-centric dashboard layout. All air brake valves, differential lock switches, and climate controls are positioned within easy reach. The combination instrument cluster gives clear, immediate readings of air pressure, oil temperature, and fuel levels.

Air-Suspended Driver Seat : Includes an adjustable air-suspension driver seat that effectively dampens road vibrations, reducing fatigue during long-distance shifts.

Spacious Sleeper Bunk & Rest Space : The extended cabin features a wide, comfortable sleeper mattress behind the seats, allowing cross-border or two-driver teams to get proper rest during standby or overnight stops.

All-Weather Climate Control : Equipped with a high-output air conditioning unit that keeps the cabin interior cool and dust-free even in scorching tropical environments.
