Types of Trailers

To move materials and goods, the trucking industry relies on a variety of trailer types. The most typical kinds of trailers consist of:

Refrigerated Trailers

An essential link in the food supply system is the refrigerator trailer. They make it possible to transport temperature-sensitive goods over long distances safely, including meats, dairy, fruit, and seafood. These specialty trailers are equipped with refrigeration units or cooling systems to maintain constant temperatures. Additionally, customized refrigerator trailers that run on energy from the truck's engine or an external power source can be made to fulfill specific cargo requirements. Food travels to its destination in ideal condition since the trailer's temperature and humidity levels are controlled.

Parcel Freight

A speedy and affordable way to move goods is with parcel freight trucks. They can move loads up to 25 tons and carry everything from little things to enormous deliveries. They have air suspension systems, sophisticated tracking equipment, and reinforced cargo sections, among other cutting-edge safety and security measures. Additionally, they can be modified to meet certain needs, like refrigeration or climate control.

Single Semi Trailers

Tractor and trailer are joined by a fifth-wheel connection to form a single articulated unit in single semi-trailers. Semi-trailers are made of strong steel frames with additional bracing to give stability when towing larger loads. A tractor that provides power and traction is connected to the trailer. Compared to conventional trucks, this combination has a higher hauling capacity since the extra trailer can support a greater weight. These are used to transport both industrial and consumer goods, such as building materials, appliances, and furnishings. Along with cattle, these big vehicles also move dangerous items or chemicals.

Drop Decks with Ramps

Ramps with a flatbed attached to a trailer with the floor lowered to the ground make up drop decks with ramps for convenient access. More adaptability, better loading and unloading, easier access for delivery staff, and enhanced freight security are some of its beneficial qualities. Drop decks with ramps help move cargo in places with restricted loading docks or narrow spaces because of the low floor and ramp.


A B-Double is a prime mover combination that is used to tow two semi-trailers. This is because, when viewed from the side, the fifth wheel coupling—which connects the two trailers—forms a “B” shape. The prime mover is directly connected to the first semi-trailer, and a converter dolly is used to link the second semi-trailer to the first. Compared to conventional tandem trailers, this enables a higher cargo capacity and more effective use of available space. Because of their improved stability and safety characteristics, B-Doubles are frequently used to transport hazardous materials, liquids, and other risky items. B-Doubles are becoming more prevalent due to the rise in demand for freight transportation.
