What is the back of a semi truck called? Understanding the Different Parts of a Trailer

When you’re driving down the highway and get stuck behind a semi-truck, have you ever wondered what the back of it is called? I know I have. It’s like this mysterious appendage that just swings around on the back of the truck, following it wherever it decides to go. Well, wonder no more my friends, because today, we’re going to dive into the world of tractor-trailers and explore what the back of a semi-truck is called.

Picture this: you’re driving down the highway, and off in the distance, you see a big 18-wheeler climbing up a hill. You slow down, trying to give it some space, but you can’t help but notice that the back-end of the truck seems to have a mind of its own. That’s because it does! The back of a semi-truck is called a semi-trailer or a trailer for short. It’s called a trailer because it’s not powered by the truck itself, but rather, it’s attached to the truck’s fifth wheel, which allows it to move with the truck but also move independently from it.

Now that we’ve established what the back of a semi-truck is called, let’s dive into some more details. Most semi-trailers come in two types: dry vans and refrigerated or “reefers.” Dry vans are just like they sound – they’re trailers that are completely enclosed, and they’re mainly used to haul dry goods like packaged foods, electronics, and clothing. Reefer trailers, on the other hand, have refrigeration units attached to their undercarriage, allowing them to transport perishable goods like produce, meat, and dairy. So there you have it, folks – now you know what the back of a semi-truck is called and the different types of semi-trailers out there. Happy truck-watching!

Terminology used in the trucking industry

Every industry has its own jargon and slang, and the trucking industry is no exception. Here are a few common terms that you might hear in the world of trucking:

  • Tractor-trailer: This is another name for a semi-truck, which is composed of two parts: the tractor (the cab where the driver sits) and the trailer (the long box that carries the goods).
  • Bobtail: A semi-truck without a trailer attached. This is also known as a power-only truck.
  • Deadhead: This term refers to a truck that is traveling empty, without a load. Deadheading can occur when a truck has delivered its cargo and is on its way back to pick up a new load or when it is going to a location to pick up a load and is empty in the meantime.
  • LTL: Less-than-truckload carriers specialize in transporting smaller shipments that don’t require an entire truck. They consolidate cargo from multiple shippers to fill their trailers.
  • Reefer: This is a refrigerated trailer that is used to transport perishable items like food or medicine.
  • Shipping dock: This is the area where goods are loaded onto and unloaded from trucks. Loading docks are typically found at trucking terminals, warehouses, factories, and other locations where goods are moved in large quantities.

Differences between types of semi trucks

There are several different types of semi trucks available in the market today. These trucks typically vary in size, weight, and capacity. One of the most important differences between types of semi trucks is the number of axles they have.

  • Single-axle semi trucks: These are the smallest and lightest semi trucks on the road. They have one axle at the rear and are typically used for shorter journeys within a city or town. These trucks are easier to maneuver and are more fuel-efficient than larger semi trucks.
  • Tandem-axle semi trucks: These semi trucks have two axles at the rear. They are heavier and larger than single-axle semi trucks and are commonly used for longer journeys and interstate haulage. The additional axle provides better stability and weight distribution, making them safer to drive on the highway.
  • Triple-axle semi trucks: These are the largest and heaviest semi trucks on the road. They have three axles and are commonly used for hauling heavy loads over long distances. They provide superior stability and weight distribution, making them ideal for long hauls.

Another important factor to consider when differentiating between types of semi trucks is the type of trailer they are designed to tow. The most common types of trailers are dry vans, flatbeds, refrigerated trailers, and tankers.

Dry van trailers are enclosed and provide protection for freight. Flatbed trailers are open and used to transport heavy machinery, construction materials, and oversized cargo. Refrigerated trailers are used to transport temperature-sensitive goods such as perishable food items. Tankers are used for hauling liquids and gases such as fuel, chemicals, and compressed gases.

Type of Semi Truck Number of Axles Type of Trailer
Single-axle 1 Dry vans, flatbeds, refrigerated trailers, and tankers
Tandem-axle 2 Dry vans, flatbeds, refrigerated trailers, and tankers
Triple-axle 3 Dry vans, flatbeds, refrigerated trailers, and tankers

It’s important to choose the right type of semi truck and trailer combination for the job to ensure safety, efficiency, and cost-effectiveness.
