The size and design of the dump truck's bed, as well as the materials it is made of, play a significant role in determining its capacity. Additionally, the gross vehicle weight rating (GVWR) of the truck, which represents the maximum allowable weight of the truck when fully loaded, also influences its payload capacity.
It is important to note that overloading a dump truck beyond its payload capacity can have serious safety and legal implications. Overloaded trucks can cause damage to roadways and bridges, increase the risk of accidents, and result in fines and other penalties.
