The towing capacity of Shunzhao´s semi trucks is extremely diverse. It is influenced by many factors for example the engine’s output, the power of the transmission, and even the truck’s style. A good example is a heavy duty semi truck which has a towing capacity of around 20 to 40 tons whilst more powerful units can handle heavier loads, sometimes exceeding 60 tons. These elements also attribute to Shunzhao’s extensive manuals for every semi truck model that assist clients in ordering suitable trucks with desired hauling skills. It is equally important to keep in mind that trying to tow beyond the recommended capacity will not only pose safety challenges, but will also result in damages to the truck and trailer.
