3 Units of Sinotruk HOWO Tractor Trucks Dispatched to Tunisia

Heavy-Duty Engineering for Tunisia’s Mediterranean Freight Corridors

Managing containerized logistics between coastal ports and inland distribution hubs across North Africa demands high engine thermal efficiency, extended maintenance intervals, and reliable powertrain pairing. Prior to sea departure, each vehicle in this 3-unit batch underwent rigorous dynamic testing tailored to Tunisian operational conditions:

1. High-Efficiency Fuel Injection Powertrain

• Powered by the proven WD615 / WP10 series diesel engines (371hp to 380hp output), these HOWO prime movers deliver maximum low-rpm torque while maintaining optimal fuel economy on highway cruise routes.

• Mated to a heavy-duty HW19710 10-speed manual gearbox, providing flexible gear ratios for effortless gradeability when pulling heavy 40ft container chassis and curtain-side trailers.

2. JOST Heavy Coupling System & Structural Frame Integrity

• Genuine JOST Fifth Wheel: Fitted with a high-strength JOST 2.0-inch or 3.5-inch cast steel fifth wheel plate with reinforced mounting brackets, ensuring smooth kingpin engagement and load distribution.

• Cold-Riveted Chassis: Built on a high-tensile steel ladder frame designed to absorb intense torsional stresses without chassis twisting under heavy payload operations.

3. Coastal Marine Protection & Cab Comfort

• Salt-Spray Shield: To counter high salinity near Port of Radès, each unit undergoes complete chassis shot-blasting, zinc-rich epoxy anti-rust priming, and a protective anti-corrosion wax topcoat.

• Ergonomic Sleeper Cab: Outfitted with a spacious HW76/HW79 wide cabin featuring double berths, high-capacity air conditioning, and reinforced cab suspension to keep drivers comfortable during long-distance shifts.
