Dump truck businesses have been a steady sector of the trucking industry. Today, there are around 27,841 registered dump truck services in the United States. They have a low market share despite their big demands in construction and mining.
Dump trucks are heavy-duty trucks with an open-box bed hinged at the rear. They commonly haul loose materials like asphalt, dirt, gravel, lumber, minerals, ores, rocks, rubbles, sand, and scrap metals. They are also used for hauling demolition waste and garbage.

Most dump trucks have a single axle on the cab and one or more axles on the dump box. Being an integral part that transmits driving torque to the wheels, the more axles a dump truck has, the heavier load it could haul. The most common type of dump truck used today has three axles.
What is a Tri Axle Dump Truck?
A tri-axle vehicle uses three driving axles besides the steering axle. These axles allow them to haul greater load weights on the road. Cement mixers, dump trucks, fire trucks, tow trucks, and wheeled cranes commonly use a tri-axle configuration.
A tri-axle dump truck is configured with a tandem drive axle and a third air-lift axle on the bed box. The lift axle can either be in the front or behind the tandem axle. Weight restrictions on public roads and highways call for dump trucks to displace a specified weight per axle. Each extra axle on the dump truck allows them to carry weight in excess of the restriction requirements.
The tri-axle design also allows dump trucks to move on cross lawns and soft grounds. When the third axle’s position is lowered, it displaces the weight of the load over a greater area to prevent the dump truck from sinking.
Operation costs of tri-axle dump trucks are much lower than axle configurations. This is because they are the lightest dump truck designs. When empty, the dump truck driver can lift the extra axle to save fuel consumption and tire’s wear-and-tear. It also allows the driver to make tight turns easier without the extra wheels.
