HOWO chassis trucks are heavy-duty commercial vehicles manufactured by Sinotruk (China National Heavy Duty Truck Group). They are renowned for their robust build, strong adaptability, and cost-effectiveness, making them a top choice for heavy transport and engineering projects worldwide.

Core Chassis & Performance

• Frame: High-strength U-shaped ladder frame (300×80×8mm) made of 700–800MPa steel. Heavy-duty models use a reinforced three-layer beam for maximum durability.
• Suspension:
  • Front: 10-leaf semi-elliptic springs with hydraulic shock absorbers.
  • Rear: 12-leaf springs with bogie suspension, ensuring stability under heavy loads.
   
• Axles:
  • Front: 7–10 ton capacity steering axle.
  • Rear: 13–16 ton heavy-duty axles (with differential lock) for high traction.
   
• Engine:
  • Weichai WP12/WP13 or MAN MC11/MC13 diesel engines.
  • Power: 371–430 hp, Torque: 1800–2500 NmSINOTRUK HOWO.
   
• Transmission: HOWO HW10/HW19710 10-speed manual or 12/16-speed AMT automatic gearbox.
• Brakes: Dual-circuit air brakes + engine exhaust brake + ABS for safety

Key Advantages

• Heavy-Duty Capacity: Engineered for 25–40 ton loads, ideal for mining and construction.
• High Durability: B10 lifespan of 1.5 million km; critical components (axles/engine) are maintenance-free for 300,000 km.
• Cost-Effective: Lower fuel consumption (10–15% less than peers) and affordable, globally available spare parts.
• Strong Adaptability: Chassis has pre-reserved mounting points for easy conversion into dump trucks, concrete mixers, cranes, etc..
