Heavy duty trailers, or semi trailers, are large unmotorized vehicles designed to be pulled by a semi truck. Semi trailers do not have a front axle and are instead supported by the back half of a semi truck, also known as a tractor unit or big rig. They are designed to be hauled long distances and are most commonly used for commercial purposes.
Heavy duty semi trailers can be made from steel or aluminum, or sometimes a combination of both. Steel semi trailers are more durable and can typically carry heavier loads, but they are more expensive to purchase and upkeep. Aluminum semi trailers are lighter, more resistant to rust and come at a lower price point. Both types of trailers are usually attached to the big rig using fifth wheel couplings.
Semi trailers come in many shapes, sizes and types. Flat bed or flat deck trailers are some of the most common types and can be used in a variety of ways. Drop deck trailers and lowboy trailers are varieties of flatbeds used for more specific needs. Dry van trailers, or box trailers, are your classic trailers for semis that include an enclosed box. Some even have conveyor belts as floors for easy unloading, known as live floor trailers. Car carrier trailers and tilt deck trailers are used to transport vehicles from factories to dealerships or to the wrecker. Tanker trailers, dump trailers and refrigerated trailers are used for more industry-specific needs like fuel, construction and food products.
