How Many Tons Can a Single Axle Dump Truck Carry

Single-axle dump trucks have a relatively small open bed that can transport construction materials or debris from landscaping projects, such as sand, gravel, or other aggregate forms. These heavy-duty vehicles have a payload capacity of up to four tons, equivalent to 7,800 pounds. In addition, larger commercial single-axle dump trucks can have as much as 7.5 tons or 15,000 pounds of payload capacity.


Capacity in Cubic Yards

The typical volume of a dump truck is between 10 and 14 cubic yards. A cubic yard can be visualized as a cube with dimensions of three feet on all sides. One yard is equivalent to 27 cubic feet. A dump truck’s capacity is approximately 270 cubic feet. The maximum load capacity of a dump truck depends on the type of truck and the bed specifications. For example, some trucks have only six-foot-long beds, while others have 10 or 12 feet. The longer the bed, the more material it can carry. However, it is vital to note that the load’s weight also plays a role. Heavier loads require larger trucks with powerful engines to haul them.

Single-Axle vs. Tandem-Axle Dump Trucks

There are two main types of dump trucks: single-axle and tandem-axle. Single-axle dump trucks have one set of wheels in the front and one in the rear, while tandem-axle dump trucks have two wheels in the front and two sets in the rear. Also, tandem-axle dump trucks are generally larger and can haul more material than single-axle dump trucks.

Size of a Single-Axle Dump Truck

A dump truck with a single set of wheels on either side of the axle is referred to as having a single-axle configuration. The bed’s age and model impact its length and width dimensions. On the other hand, they typically have a width of about 84 inches and sides of at least 24 inches high. Heavy-duty sideboards have been installed on the trucks’ sides to prevent the load from tipping. In most cases, a dump truck with a single axle has a capacity of between 10 and 12 cubic yards of snow, sand, dirt, and gravel.

Weight Capacity of a Dump Truck

Dump trucks typically have an open-bed design and a hydraulic lifting system. A dump truck’s size and weight capacity vary depending on the truck’s model and make. But typically, most dump trucks can handle between 10 and 20 tons of loads. The smaller dump trucks on pickup frames can have a weight limit as low as half a ton, whereas larger dump trucks can carry as much as 15 tons or 30,000 pounds of material. Nonetheless, it is always best to check the specific weight limit for your truck model to know how much weight can a dump truck carry and ensure that you keep it manageable by looking at the truck’s manual.

How much weight can a double-axle dump truck carry?

Regarding payload capacity, most double-axle dump trucks can carry between 13 and 15 tons, with some models capable of hauling up to 18 tons. However, the Super Dump, introduced in the 1990s, can carry a payload of 26 tons, making it the largest dump truck currently in production. While the Super Dump is more expensive, costing over $1 million, it can transport more than twice the amount of a standard double-axle dump truck, making it the perfect choice for those who require efficient and quick movement of large amounts of materials.

How to calculate the volume of a dump truck?

Calculating the volume of a dump truck is a straightforward process. Considering the truck’s bed as a parallelepiped or a three-dimensional rectangle, you can use the formula length x width x height to determine its volume. You must obtain the truck bed measurements in feet for each dimension and insert them into the formula. Once you know the volume of the truck bed, you can decide how much material it can carry. However, it is crucial to note that the density of the load also influences how much the truck can handle. For instance, lighter materials like sand or mulch take up more space than heavier materials such as gravel or concrete.

What is the empty weight of a dump truck?

While some dump trucks have three or four axles, most have a two-axle configuration. The empty weight of a dump truck varies depending on the size and type of the vehicle. Still, it generally ranges from 20,000 to 30,000 pounds. For a two-axle dump truck, the average empty weight is 24,200 pounds, while a three-axle dump truck weighs around 27,000 pounds when empty.


Selecting the right dump truck for your load requirements is crucial, and understanding its weight capacity is essential. For instance, a single-axle dump truck can carry up to 7,500 pounds, while a larger commercial dump truck can handle up to 15,000 pounds. Overloading your vehicle can reduce its useful life or damage its internal components, so it is essential to know the weight capacity before loading aggregates. Choosing a truck that does not match your needs can also result in a large truck bed, which consumes more gasoline for a relatively low output volume.
