Step Deck Trailer – Drop Deck Trailer

Step Deck TrailerStep deck trailers are also known as drop deck trailers. They are, indeed, a version of the flatbed trailer design, mainly consisting of a bottom and top deck. These trailers are specifically designed to carry and haul freight that cannot be carried or transported on a standard type of flatbed, which is usually due to height restrictions.

Step decks or drop decks are perfectly designed for heavy-haul freight carrying over long distances. Whereas regular flatbeds may not meet height requirements on some taller loads, step decks will pass easily. The cargo can have a wide variety of dimensions, from pipes to heavy-duty equipment, vehicles, turbines and more.

The maximum legal dimensions and weight for step deck trailers are:

  • Maximum Hauling Capacity: 48,000 pounds
  • Freight Dimensions:
Maximum Step Deck Trailer Length 48 ft. – 53 ft.
Maximum Step Deck Trailer Width 8 ft. 6 in.
Maximum Legal Freight Height 10 ft.

Step deck trailers are useful for a variety of jobs. Because of their hauling capacity and clearance from the ground, step decks are great choices for overheight and oversize loads alike. So, things like lumber and its related equipment, pipe and steel, oilfield products, concrete products, and coils are all commonly hauled on step deck trailers.
