What Is the Trailer Part of a Semi Truck Called?

Semi-trucks are a common sight on roads and highways across the United States. They are essential for the transportation of goods from one point to another.

The semi-truck consists of a tractor and a trailer, both of which work in tandem to move cargo from its origin to its destination. The trailer is the part of the semi-truck that carries the cargo, and it is commonly referred to as the trailer box.

The trailer box comes in various shapes, sizes, and styles. The most common type is a flatbed or dry van trailer, which is designed to carry large boxes or pallets of merchandise.

These trailers come with adjustable sides and decks that can be configured to suit different loads. Refrigerated trailers are also quite popular; they are equipped with temperature control units that keep perishable goods fresh during transport.

The trailer box is constructed from strong metal sheets that provide it with strength and rigidity. It has an aerodynamic shape that helps reduce drag while driving on highways, thus increasing fuel economy. The box also features air suspension systems that help reduce vibration while driving over rough terrain.

The back end of the trailer box houses two rear doors with hinges and locks for secure loading and unloading operations. Some models may also feature a roll-up door at the side for easier access. All trailers have lights at either side or near their rear ends for visibility when driving at night.

In conclusion, a semi-truck’s trailer part is known as the trailer box. It is made from strong metal sheets for durability, has aerodynamic designs for improved fuel efficiency, comes in various sizes and styles depending on what it needs to transport, and has lights around its perimeter for visibility when driving at night.
