Used Drop Deck Trailers For Sale

1-24 of 111

ITAG Equipment has always carried a wide selection of drop deck trailers or as some refer to them as step deck trailers. They are both the same just two different names for the same trailer depending on where you are from or what you normally call the trailer.

If we wanted to get a bit more technical could break the trailer down into two categories. A single drop deck trailer and a double drop deck trailer. A single drop deck trailer typically has about 24 inches of drop from the top deck to the bottom deck. A double drop deck trailer as well as one might imagine, has double the drop distance from the top deck to the bottom deck. Most single drop deck trailers have 10ft top decks and 38ft or 43ft bottom deck space depending on the length of the trailer.

These trailers come in two sizes. In total length, a 48ft or 53ft long are the two most common sizes. Some manufacturers make oddball sizes like a 50 or 51 or 52ft trailer. Doonan usually carries some of these different size drop deck trailers. Rarely but at times you can find some 45ft trailers on the market, but most of the time they come in 48ft or 53ft length size. The standard width across the board is at 102inches wide. When measuring the width of a drop deck trailer, you go from outside of side rail or as some call it a rub rail to the other side. So outside to outside measurement from side rail to side rail are how you measure the trailer. If you measure from outside of deck space to the opposite outside of deck space, it’ll hit right at 96 inches, but that’s not how these trailers are measured unless the trailer does not have a side rail. Kingpin setting on these trailers is at times set in funky positions. Commonly they measure about 18 inches deep.

Starting from the front of the trailer to the center of the kingpin is how you measure the distance. If you have a short top deck length, then this measurement could be important depending on what kind of semi truck you have and where the fifth wheel is positioned on the tractor truck. If the king pin setting is too deep and the top deck is short, and your fifth wheel isn’t set back far enough or is not able to slide back then you could hook up to a trailer that won’t work with your 18 wheeler truck. You may have to figure out how to get your fifth wheel to slide back. Even after moving the fifth wheel around it could throw row-5-gutter off your weight distribution and render the semi truck and trailer combination useless for hire operations without some major custom fabrication that could be costly. Drop Deck or Step Deck Trailers are considered to be highly versatile trailers as they can be used to carry vehicles, heavy equipment, construction equipment, paving equipment, piping, cars, vans, military vehicles, and more. Drop deck trailers can be outfitted with beaver tail and ramps on the back for ease of loading as well as aluminum ramp kits that are installed on the side of the trailer. The aluminum ramp kits can also double as load levelers to enable the truck driver to be able to use the trailer like a flatbed or flat deck trailer. The height of the bottom deck on the step deck trailer allows for taller loads to be able to be hauled on the trailer than what can be done on a flatbed.

Trucking can be a game of pounds and inches with a constant need to be able to be as low and light as possible to avoid having to obtain overweight or over height permits which can be costly depending on the distance traveled. Drop deck trailers come standard with two different types of flooring. Either wood floor or aluminum flooring. Steel, rubber or other flooring types can be installed on drop deck trailers as well, but wood or aluminum are the two most common. Cross-members are the steel or aluminum construction i-beams that run horizontally down the trailer from left to right or right to left whichever way you choose to look at it. Aluminum cross-members are better for making the trailer lighter and have less corrosion risk that steel cross-members typically carry. There could be a case made for durability or strength between the two metal materials used, but aluminum is being widely used across the marketplace from passenger vehicles to trailers and has a lot of advantages from weight to less prone to rust to others. ITAG has refurbished and seen many used drop deck trailers over the years, and if we were truckers in another life, we would prefer to have aluminum cross-members on all of our trailers. Main beams on drop deck trailers are made of steel or aluminum. Most all trailer manufacturers make all aluminum or combination style trailers.

Steel and wood step deck trailers are the heaviest and all aluminum or trailers with more aluminum construction tend to be lighter. Double Drop Deck Trailers are in the same family as single drop deck trailers but look a lot like lowboy trailers and are confused as lowboy trailers a lot of times. Double drop deck trailers can have a stiff neck or a removable neck. Double drop deck trailers will have a loadable top deck and bottom deck. Lowboy trailers do not have loadable top decks. Double drop deck trailers can be rated by capacity as well such as 35 ton or 40 ton. There are many variations to choose from depending on the application the trailer is being used.
