Sinotruk HOWO 156 horsepower can pull up to ten tons at maximum. Here are the relevant introductions: 1. Sinotruk HOWO: Sinotruk HOWO is one of the main products of Sinotruk, with high popularity in the heavy-duty truck industry, possessing obvious technological and market advantages. It has also established overseas sales networks and is very popular in the international market. 2. Vehicle pulling capacity: It refers to the work done by one metric horsepower per second to lift a 75-kilogram object by one meter, and the power unit is also expressed in horsepower. The pulling capacity of a vehicle mainly depends on the rated power of the engine. The engine's rated power will be marked on the vehicle's identification plate, generally located on the engine nameplate under the hood. Some models place the nameplate under the driver's seat, and it will also be announced in the vehicle's user manual, which can be checked by yourself.

I've been driving trucks for several years and currently use the Sinotruk HOWO 156 horsepower model for long-distance hauls. This type of truck has moderate horsepower and can generally carry 5 to 6 tons of cargo, which is a reasonable range. Exceeding this limit makes it difficult to climb hills or maintain speed on highways, and fuel consumption will also increase significantly. The vehicle's configuration, such as chassis strength and tire size, has a significant impact. For example, with an all-aluminum cargo box, carrying 5 tons is stable and secure. When driving, I always keep the load within 5.5 tons for safety and peace of mind. Remember to regularly check the suspension and braking systems, and avoid overloading. Otherwise, parts will wear out faster, leading to higher repair costs and more headaches. For long-distance freight, over time, the performance of tires and the engine becomes noticeable. Proper maintenance can extend the vehicle's lifespan by several years.

As a freight professional, I pay close attention to the load capacity of the HOWO 156 horsepower truck. Under standard conditions, it can carry around 5 tons, with the horsepower and torque well-matched, delivering optimal performance at around 1500 rpm when heavily loaded. The vehicle manual indicates a maximum design load of approximately 5 tons, but actual operations depend on road conditions. In urban areas, it can easily handle 5 tons, but on rough rural roads, it's best to reduce the load to 4 tons. Economically, carrying around 5 tons offers the best fuel efficiency, avoiding frequent acceleration and deceleration that consume more fuel. Upgrades like reinforced springs might slightly increase capacity, but it's not worth the risk of overloading—high risk with low returns. Fleet experience suggests keeping the load within 80% of capacity is the most cost-effective, minimizing per-trip costs.

Having repaired trucks for many years, I've encountered common load capacity issues with the HOWO 156 horsepower model. The factory-set maximum load is generally around 5 tons, but during actual road tests, exceeding 6 tons often leads to problems such as leaf spring fractures. Customer feedback indicates smooth operation at 5 tons, with fuel consumption surging over 20% when overloaded. Key inspections should focus on chassis load-bearing capacity and tire load index, as overloading can cause transmission system damage. Regular maintenance of brake pads and suspension can maintain load efficiency. From a safety perspective, regulations limit loads to within 5 tons to avoid fines, and owners should be aware of their vehicle's specific placard data.
