The Parts of a Freight Truck

Take a look at a short overview of the parts of a freight truck.

We probably see them on the road every day, but it can be easy to take for granted that a freight truck has a specific design where each piece plays a key role. Today we’re getting back to basics. If you have never gotten up close to a freight truck, are new to trucking, or a veteran looking for a refresher, then take a look at a short overview of the parts of a freight truck. 

Front End

Starting with the front, probably the most important part of a freight truck is the tractor unit, which is the part you drive that is used for towing the cargo. The tractor unit contains the engine compartment in the front, where the engine lives under the hood. There is also the cabin where the truck driver goes, and sometimes there may be a sleeper compartment as well. Underneath the tractor unit are the fuel tanks which sit behind the front wheels. And on top of the tractor unit is a wind deflector, also called an air dam, which works like a visor to help cut down wind resistance on the highway.

The Back

As for the rest of a freight truck, you will probably see most attached with a semi-trailer in the back. This is usually an enclosed cargo space, but it can also be a flatbed for hauling other types of cargo. The semi-trailer runs on tandem axle wheels in the back, and the front of it has foldable legs called landing gear, which can keep the front end of the trailer up when it is not attached. Everything that can be towed by the tractor unit gets attached via a fifth-wheel coupling mechanism.
