Lowboy Trailers are great semi-trailers for hauling heavy loads or over dimension loads. Lowboy trailers provide a low ride height that makes taller loads get under bridge laws and low hanging street lights or power lines. Lowboy trailers come in a variety of sizes but most are 48 or 53 feet long.

The well type and length of lowboy trailers is very important as it determines what size and kind of equipment can be hauled on it. The well length of lowboy trailers can range from as short as 20ft to as long as 30ft. Extendable lowboy trailers can add even more length to the well for extraordinarily long cargo. Some wells can have bridges in the middle or flat or boom wells over the rear axles so is important that the well type accommodates the kind of equipment you’ll be loading. Most lowboy trailers will be 102 inches wide but have outriggers or slide outs along the side that can make the width of the trailer wider to help carry your wider wheeled or tracked loads. Most lowboy trailers do not come with winches on the side and truckers use chain and binders to secure the cargo being hauled on the semi-trailer. Generally, most all lowboy trailers are made out of steel frame, steel cross-members and a steel outer construction with wood floors.

Lowboy trailers come in a mixture of different axle variations from tandem to Tri to quad and more. Flip axles, jeeps, and boosters are common accessories that help the lowboy trailer haul bigger and heavier loads. Some extremely heavy duty lowboys can have multiple axles, jeeps, boosters, spreader bars, neck extensions, and other add-ons to help assist with the heaviest of cargo transportation. Lowboy trailers have many different neck variations to them to help with the loading and unloading of equipment. Mechanical detach lowboy trailers have a necking system that attaches and detach manually with a system of locking pins, levers, keepers, shackles and semi-truck assistance.

Lowboy trailers are also made as hydraulic detach lowboy trailers that mainly come in two different styles. Ground bearing and non-ground bearing lowboy trailers. Ground bearing lowboy trailers are fairly self-explanatory. The hydraulic rams use the ground to push off of to raise and lower the height of the lowboy as well as to connect and disconnect the neck from the semi-trailer. If you see a lowboy trailer that has hydraulic rams that use the ground underneath it to push the trailer up and down then it is a ground bearing lowboy. Non-Ground bearing lowboy trailers have hydraulic systems that do not use the ground to push off of. These lowboy trailers either push off the trailer or work off the 5th wheel of the semi-truck to connect and disconnect for loading and unloading the semi-trailer. Here is another older lowboy video showcasing how non-ground bearing lowboy trailers connect and disconnect: https://www.youtube.com/watch?v=siQPB7ye_tY&t=118s

Many different types of lowboy trailers function, connect and disconnect in different ways depending on how the manufacturer has designed the process of attaching and detaching the neck of the lowboy trailer. Hydraulic detach lowboy trailers function off of a wet line kit that is connected to the semi-truck or a pony motor system that is attached to the trailer to assist with connections.
