Trailers have been around for over a century. They started as simple verbal communications that trailed feature films. They were often printed on the trailing portion of the feature print stock, a method that kept the print clean. These early trailers were intended to entice audiences to leave the theater. They emphasized the film’s premise and introduced the main characters.
Trailers are often used to transport cargo. The gross vehicle weight rating (GVWR) is used to calculate the correct size for the trailer. Other factors to consider when choosing a trailer include the type of hauling and the distance travelled. There are many different types of trailers available on the market, so it’s important to find out what is right for you.
In addition to its function as a promotional tool, a trailer can serve as a visual advertisement for a movie. Many movie trailers feature creative talent and serve as a sneak preview of the film. Some trailers even include the movie’s release date. If you’re a fan of movies, or just want to know more about the film’s plot, you’ll want to watch the trailer.
To protect your trailer and your car, you’ll want to secure the trailer with safety chains. These chains are connected to the towing vehicle with a ball mount and prevent the trailer from detaching from the vehicle. Safety chains must be long enough to keep the coupler from dragging on the road. They should also have a certain amount of slack to allow the trailer to turn freely.
Weight distribution of your trailer is also a key factor. The hitch weight of the trailer should be at least 10 percent of the gross weight of the vehicle you’re towing. Ideally, this will give you an extra 10% margin of safety. Moreover, make sure your tow vehicle has adequate rear suspension, and make sure the trailer is level before you hitch it.
Safety lights on a trailer are another essential safety precaution. They alert other road users to the trailer’s presence. These lights can be incorporated into the housing unit or installed separately. They can be yellow or red in color. They also need to be properly mounted and securely fastened. The Department of Transportation (DOT) has specific regulations regarding trailer lighting.
Another important safety feature on a trailer is its brakes. Under federal law, a trailer that has a GVWR of three thousand pounds or more needs to have brakes on each axle. If it does, it must be equipped with air or electric brakes. Moreover, the brakes should be strong enough to keep the trailer in place.
The fifth-wheel hitch is another safety device on a trailer. This type of hitch allows the trailer to rotate, although it has limited tilt side-to-side. It is used for agricultural and industrial trailers. It couples with the tow vehicle with the use of side rails.
