A trailer is a wheeled vehicle designed to be pulled by a car, truck or other traction engine for hauling cargo. Trailers are also used to carry boats, animals, and some campers. Trailers are usually equipped with a hitch that is attached to the towing vehicle, and they may have a storage compartment or living quarters. The term “trailer” is also used to refer to a film preview or advertisement that theaters show before a movie.
The first trailer was created in 1913 by Nils Granlund, advertising manager of the Loew’s chain of theaters, who spliced rehearsal footage of a Broadway play into a short promotional montage that trailed the feature presentation. It was a revolutionary concept for the entertainment industry because it allowed movie studios and theaters to compete with each other for audience attention.
Since then, trailers have become increasingly sophisticated and creative, with the ability to tease out the general plot and mood of a movie without giving away too much information. They are now used not just for movies but also for TV shows, video games and even book previews.
One of the key factors in creating a successful trailer is deciding on the right music. An awesome piece of music can totally make or break a trailer, and it doesn’t always have to be super dramatic either. For example, the Mission Impossible trailer uses the song Friction by Imagine Dragons and it completely captures the feel of the movie. The song and editing work together to create a goosebump-inducing experience, leaving the viewer wanting more.
Another great example of a killer trailer is the one for The Lion King, which only lasts 4 minutes but is able to capture so much emotion and the movie’s main theme around family and life. It’s also a testament to the power of the movie that it is still as loved today as it was when it was released back in 1994.
A trailer can be also used for hauling oversized loads, such as oil rig modules, bridge sections, buildings, ship sections and industrial machinery. Such heavy-duty trailers are often powered by diesel engines and have hydraulic lift mechanisms. They are usually towed by tractors, but there are also self-powered units called SPMT (Self-Propelled Modular Transporter) that use hydraulics to maneuver the load and do not need an external power source.
A trailer can also be used for camping, and the choice of which to purchase depends on what kind of adventures you want to go on. If you’re going to be travelling long distances, a travel trailer is probably your best option, as it can be towed by a regular car or pickup truck and will have plenty of space for all your belongings. It’s important to find a trailer that’s comfortable and easy to drive, and you should also consider the weight of your belongings to ensure it can be safely towed. A smaller trailer is better for travelling around city streets, while a larger one is more suitable for long drives and rough terrain.
