A trailer is a large vehicle, often resembling a semitrailer, used to haul freight over long distances by road. Also known as a van, wagon or cart, trailers come in a wide variety of sizes and designs to accommodate different types of cargo. They may be equipped with a cargo hold or loading bay, allowing for easy access to and transport of goods. Some types of trailers are designed to carry livestock, while others are built for the transport of machinery and equipment. They can also be customized to meet specific business or personal needs.
A film trailer, or trailer preview or attraction video, is a short advertisement that highlights key scenes from a movie due for release. It is usually screened prior to the main feature at a theater or cinema and serves as a promotional tool. Some film trailers contain footage that is not included in the edited movie. A few trailers even incorporate dialogue that is not spoken in the finished film. Beginning in the 1990s, several DVDs have been released containing only film trailers.
The trailer is also a common term for a small caravan that has been equipped with kitchen facilities and sleeping arrangements, to be used as an RV or mobile home. It may be towed by a car, truck or another motorized vehicle.
For commercial or industrial use, a large trailer that has rails for transporting vehicles and equipment is called a railroad trailer or intermodal container trailer. It has a rear ramp and can be loaded from the side or back. It can be fitted with a hydraulic lift to facilitate loading and unloading.
When purchasing a trailer, it is important to consider the load size and weight capacity, as well as the towing vehicle compatibility. It is also necessary to assess the environment and road conditions in which the trailer will frequently travel. Depending on the type of cargo, additional features like refrigeration units or adjustable partitions may be required.
Lastly, a trailer should be compatible with the towing vehicle’s electrical system. In some cases, a special converter is needed to connect the trailer’s lights to the car’s power.
