What Is a Step Deck Trailer?

You’ve probably seen hundreds of semis with flatbed or step deck trailers over the years and not thought much about the difference. Maybe you didn’t even know there was such a thing as a step deck trailer at all. When hauling large items, there are certain advantages to utilizing a step deck, also known as a drop deck or lowboy trailer. Let’s examine the facts about step deck trailers, the difference between them and flatbeds, and why you may want to use one in the future.

Step Deck Trailer Definition

A step deck trailer is designed to carry cargo that is too tall to go on a flatbed truck. A step deck truck can help you haul loads without having to obtain special permits for exceeding the legal height limit. These trailers have a lower and upper deck, hence the use of the term “step” in the name. This also makes it much easier to load and unload equipment, especially with a forklift.

There are different types of step deck trailers, such as fixed-neck, gooseneck, or removable gooseneck, which you can use depending on your needs for loading and unloading. A fixed-neck trailer has limited options, whereas a removable gooseneck can be loaded either on the front or back of the trailer. How tall is a step deck trailer? These trailers typically have a lower deck height of 3 feet 6 inches.

Freight Carried on Step Deck Trailer

So what kind of freight is typically carried on step deck trailers? These trailers usually accommodate heavy machinery and freight that tends to be higher. The typical step deck truck loads include the following items:

  • Excavators
  • Tractors
  • Building Materials
  • Agricultural Materials
  • Other Machinery

Obviously, these items can be quite high and depending on the specific state law, they may exceed the maximum allowable height, especially for things like bridge clearance. This is where step deck trailers really come in handy.

Flatbed Trailer Vs Step Deck Trailer

There is obviously a key difference between step deck vs flatbed, but it’s mainly just the step deck dimensions. When it comes to length and width, the step deck and flatbed have the same dimensions, but there is a key difference with the height of these trailers. With the lowered deck, as mentioned before, the step deck dimensions allow for larger cargo to be hauled, even if all the other specifications are pretty much the same, including the weight limit.
