The Dimensions of a Tractor Trailer Bed

Tractor trailers, also known as semi-trucks or 18-wheelers, are one of the most common sights on American highways. These massive vehicles are capable of transporting large quantities of goods across vast distances. The tractor trailer bed, or trailer, is where the cargo is loaded and secured for transport. But how wide is a tractor trailer bed? In this article, we will explore the dimensions of a typical tractor trailer bed and how they vary based on the type of trailer.

Standard Trailer Width

The width of a tractor trailer bed varies depending on the type of trailer, but the standard width is 8 feet and 6 inches (2.6 meters). This means that the trailer can accommodate a standard shipping container, which is 8 feet wide. However, it is important to note that some states have restrictions on the width of a tractor trailer, which may require the trailer to be narrower than the standard width. In such cases, the cargo may need to be loaded and secured differently to ensure compliance with state regulations.

High Cube Trailers

High cube trailers, also known as tall trailers, are designed to accommodate taller cargo that cannot fit into a standard trailer. These trailers are usually 9 feet and 6 inches (2.9 meters) tall, which gives them an additional 12 inches (30 centimeters) of vertical space compared to standard trailers. However, the width of high cube trailers is the same as standard trailers, which means that the cargo must be loaded and secured in a way that takes into account the additional height.

Flatbed Trailers

Flatbed trailers are used to transport oversized cargo, such as construction equipment, machinery, and building materials. These trailers are usually wider than standard trailers, ranging from 8 feet and 6 inches (2.6 meters) to 10 feet (3.1 meters) in width. The flatbed trailer is open on all sides, which makes it easier to load and unload oversized cargo. However, this also means that the cargo must be securely fastened to the trailer to prevent it from shifting or falling off during transport.

Refrigerated Trailers

Refrigerated trailers, also known as reefers, are designed to transport perishable goods, such as food, medicine, and chemicals, at a specific temperature. These trailers are usually the same width as standard trailers, but they have insulation and refrigeration units built in to maintain the desired temperature. The refrigeration unit requires a power source, usually provided by the tractor, to keep the cargo at the required temperature. The cargo must be loaded and secured in a way that allows for proper air circulation and temperature control.

In Summary

In conclusion, the width of a tractor trailer bed can vary depending on the type of trailer. The standard width is 8 feet and 6 inches, but high cube trailers, flatbed trailers, and refrigerated trailers all have different width requirements. Understanding the dimensions of these trailers is important for shippers, trucking companies, and drivers to ensure that cargo is loaded and secured correctly for transport.
