Flatbed trailers are basic, but versatile, open trailers. They are ideal for hauling a variety of loads. Loading of these trailers is usually done by forklift from the side, dock loading from the rear, or by overhead crane. One advantage of the flatbed trailer is the maximum continuous deck space. Most flatbed trailers are between 45’ to 53’ in length and 96” to 102” in width, Doonan produces them anywhere from 24’ to 60’ in length and 96” to 114” in width. Additional lengths, up to 90’, can be achieved by purchasing an Extendible flatbed trailer. Typically, flatbed trailers have a maximum high of 60” at the front tapering to a standard dock height of 54” in the rear. This results in a maximum freight of 8’4”. If taller loads are required, a Drop deck trailer should be considered.
Flatbed Trailers are made of steel, aluminum or a combination of steel and aluminum. Generally, a flatbed trailers weighs between 8,000 and 12,000 pounds, but the weight can vary greatly depending upon the options installed on the trailers. Doonan offers hundreds of options for its flatbed trailers. While most flatbed trailers have a Gross Vehicle Weight Rating (G.V.W.R) of 80,000#, the concentrated load capacity can vary greatly. The concentrated load capacity is the maximum weight the beams of the trailer can carry in a 10’ or 4’ section of the trailer. Doonan manufactures flatbed trailers with concentrated load capacities between 50,000 and 110,000 pounds. Other common names for flatbed trailers include Flats, Flat Decks, Floats, Oilfield Floats, and High Boys.
