Engine size, load volume, dump bed design and the of number of axles are some of the common dump truck specifications. These dictate how well the unit can be maximized of satisfy the requirement.
The power of the vehicle is primarily dependent on its engine size. The bigger the engine size, the more power the truck has. Engine size is determined through the amount of diesel or gasoline it can contain. The load volume is gauged by how much the truck can accommodate based on cubic yards, instead of weight.
The dump bed design is a specification where variation is often observed. Most dump trucks are designed with a rear unloading dump bed. This is done by just lifting the dump bed and emptying its contents out. Two other designs include a side dump and a bottom dump. Operators who want the load emptied neatly onto the surface can make good use of the bottom dump design.
The number of axles determines how much load the dump truck can accommodate. While trucks with single rear axles require less maintenance and can have fewer dragging issues, they also have limited capacity. Trucks with more axles offer a better weight distribution, thus allowing more room for additional load.
