The 4200x2000x1200mm cargo compartment provides substantial volume for commercial deliveries while maintaining strict temperature uniformity throughout the load space.

Built on Sinotruk's acclaimed HOWO platform, this refrigerator truck benefits from decades of engineering refinement and manufacturing excellence. The 6x4 drive configuration delivers superior traction and payload distribution, making it equally effective on highway corridors and challenging rural delivery routes. With comprehensive after-sales support including onsite installation, video technical assistance, and field maintenance services, operators can deploy this vehicle with confidence in its long-term reliability and performance.

Performance & Engineering

The heart of this HOWO refrigerated truck lies in its powerful diesel powertrain, producing between 251-350 horsepower with a peak torque output of 2000-2500Nm. This substantial power delivery ensures confident performance whether navigating mountainous terrain, accelerating onto highways, or maintaining consistent speeds under full load conditions. The engine's robust construction and proven reliability translate to extended service intervals and reduced downtime, critical factors for commercial operators managing tight delivery schedules and fleet utilization targets.

The six-speed manual transmission provides precise control over power delivery, allowing drivers to optimize gear selection for varying load conditions and road gradients. The transmission's durable gearset is designed to handle the high torque outputs typical of heavy-duty diesel engines, ensuring smooth shifts and long-term durability even under intensive commercial use. The 6x4 drivetrain configuration distributes propulsion forces effectively across multiple axles, improving traction on slippery surfaces while maintaining acceptable axle load limits for standard road regulations.

The chassis engineering demonstrates Sinotruk's commitment to payload capacity and structural integrity. The vehicle's gross weight rating of 5-10 metric tons accommodates substantial cargo loads while remaining within practical limits for most commercial route infrastructure. The robust suspension system, featuring heavy-duty leaf springs and shock absorbers calibrated for cargo vehicle applications, protects both the payload and chassis components from road-induced stresses. The ladder-type frame rail construction provides exceptional torsional rigidity, maintaining alignment under dynamic loads and extending component service life across hundreds of thousands of kilometers.
