Step Deck Trailers, also sometimes referred to as “Drop Deck Trailers”, or “Single Drop Trailers”, are a version of the Flatbed Trailer, but in addition to the regular flatbed, have a rising “step” deck toward the front of the trailer.

These trailers are utilized for taller shipments that are not allowed on a regular flatbed trailer, usually due to height restrictions. It’s also easier to transport equipment, such as construction vehicles and tractors, since many Step Deck Trailers are equipped with rear ramps, allowing for the equipment to easily be driven up and onto the trailer.

Standard Specifications of a Step Deck Trailer

STEP DECK TRAILER LENGTH

The standard length of a Step Deck is usually about 37’on the bottom deck, and 15′ on the top. This allows for movers to, for example, drive a tractor up onto the bottom deck, and then perhaps load a partial-load on the top, depending on the overall weight.

STEP DECK TRAILER WIDTH

Allowed width for your freight is 8’6″ in usually every scenario unless you have a permit for going wider, in which some varying degree of an overhang is allowed, depending on the permit type. For the most part, however, these requirements and restrictions are state-dependent, so check with our specialists on your load.

STEP DECK SHIPMENT WEIGHT

The weight allowance for a Step Deck is the same as the weight allowance for a Standard Flatbed, which is usually between 48,000 – 53,000 pounds, depending on the newness and materials the trailer was manufactured with.

STEP DECK LEGAL SHIPMENT HEIGHT

One of the most important aspects of the differing specifications between a Standard Flatbed and a Step Deck, the Step Deck allows for a greater height threshold because of it’s front step. The standard height for a Step Deck is 11′ high, but the rule of thumb, as in most cases, is 6″ of clearance, making 10’6″ the normal height restriction. This is about 2 feet of extra clearance than the Standard Flatbed, without the need for a permit, making it an ideal choice for higher shipments such as tractors, different types of machinery, and anything that’s over the height of 9′ tall.
