The Sinotruk Howo truck cargo box is designed to meet different customer needs. It comes in sizes ranging from 10 to over 20 cubic meters. This flexibility allows the truck to handle both light and heavy loads. From my experience, this adaptability makes a big difference when transporting various loads, as I can choose the right size for each job.
A key feature is the hydraulic dumping system in the cargo box. It makes unloading easier, and the driver can control it with buttons or switches. I’ve found that being able to adjust the dumping angle and speed improves safety, especially in tight or uneven spaces. This makes the whole process faster and safer.
Tires and Wheels
Sinotruk HOWO trucks feature different tire and wheel options to meet the needs of heavy-duty operations.
The tire load and speed ratings are important for the performance of Sinotruk HOWO trucks. For instance, the 12.00R20 tires, rated at 154/151K, can handle tough conditions. The 315/80R22.5 tires, rated at 156/153L, offer great load-bearing and speed performance. The tread depth of these tires ranges from 18.0MM to 25.0MM, depending on the size and model. This ensures good traction and long-lasting use. Most tires used in these trucks meet global standards like ECE and DOT for safety. Typically, these trucks have 12 tires plus a spare, ready for long operations. Sinotruk HOWO trucks also use trusted tire brands like Double Coin, known for their durability, load capacity, and resistance to wear, making them ideal for heavy-duty use.
Brake System
The braking system in Sinotruk Howo trucks prioritizes safety, reliability, and efficiency. It uses advanced technology to deliver strong performance.
Service Brake includes a dual-circuit compressed air braking system. This system splits the braking process into two circuits. If one circuit fails, the other keeps the truck under control, boosting reliability and driver confidence.
Parking Brake, also known as the Emergency Brake, works with a spring energy mechanism that applies force to the rear wheels, keeping the truck stationary. In some models, it can also engage both the front and rear wheels for stronger braking power. This provides an added layer of safety in emergencies.
Auxiliary Brake uses the engine’s exhaust valve to provide extra braking power when needed. This system eases the load on the main brake, especially useful on steep descents or when carrying heavy loads. It helps ensure both safety and durability in tough conditions.
The Sinotruk Howo trucks have a four-circuit protection valve in some models. This improves safety by preventing system failures. It ensures the braking system works reliably, even in critical situations. The trucks also have front and rear drum brakes, which perform well in many conditions. Many Howo models are equipped with an anti-lock braking system (ABS). ABS helps prevent the wheels from locking up during hard braking. This gives drivers better stability and control, especially in emergencies. From my experience, ABS makes a big difference, offering more confidence when driving in tough conditions.
Steering System
Driving a Sinotruk Howo truck feels like steering a powerful machine. The hydraulic power-assisted steering makes the truck feel lighter and more responsive, even in tough conditions. This control gives you confidence, making every turn smooth and easy.
Key Features of the Steering System
- Hydraulic Power-Assisted Steering: This system reduces the effort needed to steer, making the vehicle easier to control.
- Power Steering with Double T-Cross Section Beam: The front axle has a double T-cross section beam for extra strength and stability.
- Full Hydraulic Steering with Vane Steering Pump: Some models, like the ZF8098 and ZF8118, use a full hydraulic system with a vane steering pump for better performance.
Operational Details
The steering system uses hydraulic power assistance, which makes turning the wheel easier and provides a smoother, more responsive driving experience.
Potential Issues and Solutions
- Heavy Steering: If the steering is hard to turn, it might be because the steering fluid is low or the booster system has failed. Check the fluid level and inspect the system.
- Steering Rattling: If the steering makes a rattling sound, some parts may be worn or loose. Tightening or replacing these parts should fix the issue.
- Unstable Steering: Unstable steering could be due to damaged parts or improper adjustments. Have a mechanic check the system.
- Excessive Steering Wheel Play: Too much play in the steering wheel may come from worn parts or incorrect brake adjustment. Inspect and replace any worn components.
- Steering Wheel Shaking: If the steering wheel shakes, it could mean there are damaged parts or improper setup. Get the system checked immediately to prevent further damage.
Maintenance and Repair
If there are problems with the steering system, take the truck to a professional repair shop. The repair cost will vary depending on the model and the issue, especially if parts need replacing.
Steering Ratio
ZF8098 Model: The steering ratio for the ZF8098 model is 22.2-26.2, offering a good balance of precision and ease of control.
Electrical System
The electrical system in Sinotruk Howo trucks provides reliable power for various truck components. It is essential for the operation of systems like the engine, lights, and instruments.
The Sinotruk Howo trucks have a central controller that allows for manual checks with clear, easy-to-read indicators. These indicators track important operational parameters, such as air pressure, coolant temperature, engine oil pressure, and battery charge. From my experience, these combined indicators make it easier to diagnose issues quickly and manage the vehicle effectively. This can help prevent expensive breakdowns. For instance, when I drove a Howo truck on a long trip, the system’s alerts kept me on top of maintenance needs. This made the journey safer and more efficient.
Cab and Comfort Features
The Sinotruk Howo trucks are built to prioritize driver comfort and convenience. They come with a variety of advanced cab features that make driving smooth and comfortable, especially on long journeys.
