A Tri-Axle Truck & Trailer: What Is It?


Tri-axle trucks and trailers have three axles, as you could assume from the name. In the further description, it features a set of three axles at the back of the vehicle or trailer.

With this style of arrangement, a truck driver may raise and lower the axle using controls within the cab. When there is no weight, the tire may be lifted off the ground thanks to the tri-axle design.

The benefit of being capable of lifting axles off the road is that they are not used when they are not required to transport a big load. This improves fuel economy and lessens tire wear.

Not all trailers and trucks are made equally. Different vehicles and trailers have varying weight capacities. Many businesses utilize tri-axles trucks and trailers in their supply chain to deliver large products because of their weight capability.

When delivery of products weighs between 55,000 and 65,000 pounds, a two-axle trailer’s weight-bearing capacity usually isn’t enough to transport it. The use of a tri-axle vehicle or trailer is thus required. In addition, the amount of weight that each setup is permitted to transport is governed differently by each state.

For each kind of trailer design, each state sets its own regulations on the maximum weight that may be transported lawfully. Therefore, you must adhere to state regulations and check the weight threshold at which a third axle on the trailer is required. It can be expensive to pick up the incorrect chassis with a drayman when a tri-axle is required.


Quad-Axles vs. Tri-Axles trucks

Tri-Axle Trucks


Tri-axles provide several benefits over quad-axles, including being smaller, lighter, and less costly.

Tri-axles are more frequently used for local haulage and cost less to operate than quad-axles since they have fewer axles. They frequently deliver bulky supplies to building sites. Since they can access more constrained areas, things may be transported to their goal with more ease.

Quad-Axle Trucks


Typically, a quad-axle truck has two powered and two unpowered axles.

They can withstand larger loads than tri-axles since they have four axles. Their increased size implies that they sometimes cost more to maintain, which is a drawback. Even with increased maintenance costs, they are nevertheless frequently the better option for moving huge goods over long distances.

You could discover that each state has a separate set of load weight requirements for freight that must traverse state boundaries. The safest option for compliance in all states is the quad-axle.
