Tri axles, more hauling power
A tri axle dump truck is a heavy-duty hauling machine equipped with three axles at the rear, designed to carry larger payloads while maintaining stability and maneuverability. These trucks are widely used in construction, aggregates, road building, and site prep projects where moving bulk materials efficiently is essential. At Ritchie Bros., listings often feature popular makes and models of tri axle trucks for sale, including well-maintained used tri axle dump trucks with detailed inspection reports.
How big is a tri-axle dump truck
The size of a tri axle dump truck can vary depending on manufacturer and configuration, but most fall into the medium-to-large category of dump trucks. Typical dimensions include an overall length of 20 to 25 feet and a dump body capable of handling 15 to 20 cubic yards of material. Compared to tandem axle models, a tri axle truck offers increased carrying capacity while distributing weight more evenly across its axles for better road performance.
How much can tri axle's haul in cubic yards?
Payload is one of the defining advantages of a tri axle design. In many states and provinces, a tri axle dump can legally haul between 15 and 22 tons of material, depending on local weight regulations. In terms of volume, that usually translates to 15–20 cubic yards of material such as gravel, sand, asphalt, or demolition debris. For contractors and operators, this means fewer trips, lower fuel costs per ton moved, and more efficient project completion.
Tri axle dump trucks with pup-trailers
Some operations pair a tri axle dump truck with a pup trailer to maximize hauling capacity. A pup trailer is an additional dump trailer pulled behind the main truck, equipped with its own hydraulic system for unloading. This combination allows operators to move nearly double the payload in a single trip while still retaining the flexibility to dump each body independently. While not always necessary, the tri axle + pup setup is a common choice in high-volume hauling applications like highway construction or quarry operations where efficiency is critical.
Key Buying Considerations
When searching for a tri axle dump truck for sale, a few critical factors guide the decision:
- Capacity & Legal Limits – Ensure the truck matches hauling needs while complying with regional weight restrictions.
- Condition – Review inspection reports for body wear, frame condition, hydraulics, and drivetrain health.
- Brand & Parts Availability – Leading makes such as Mack, Kenworth, Peterbilt, and Freightliner offer strong aftermarket support.
- Configuration – Consider whether a standalone truck or a truck-and-pup setup is best suited for the workload.
