There are several different types of freight trailers available, including flatbeds, enclosed, and refrigerated options. But if you’re looking to transport heavy equipment or goods that may exceed the legally allowable height, you need to search for low boy trailers. Even if you’ve seen one on the highway, however, you may not be familiar with how they work. Below is everything you need to know about them.

Characteristics of a Low Boy Trailer

low boy trailerA low boy, which is also known as a double drop, is a flatbed trailer that has two levels on its deck. The second level is its main selling point, as it sits low to the ground, allowing you to carry tall cargo that would otherwise not fit under bridges and overpasses. The maximum legal height of the trailer and cargo combined is 14 feet in Hawaii. Low boy trailers ensure your equipment stays under that limit. They are commonly used to transport heavy construction machinery, such as bulldozers and excavators, and industrial materials.

Types of Low Boy Trailers

Low boy trailers are classified by the way they attach to your truck. Fixed goosenecks have longer decks, while fixed necks are the lightest. Hydraulic detachable trailers are the easiest to disconnect, mechanically detachable models are used for long specialty hauls, and mechanical folding goosenecks have decks that fold down to ground level. You can also choose one based on the suspension it uses. Spring-ride is the least expensive, air-ride offers a smooth drive, hydraulic allows more axle movement, while independent suspension provides more stability.
