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 drive a tractor or large wheeled/tracked vehicle up onto the bottom deck. Then they may load a partial-load on the top, depending on the overall weight.

STEP DECK WIDTH

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

STEP DECK 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. This depends on the newness and materials the trailer was manufactured with.

STEP DECK LEGAL SHIPMENT HEIGHT

The most important difference between a Standard Flatbed and a Step Deck is that it allows greater height. The standard height allowed for a Step Deck is 11′. But the rule of thumb is 6″ of clearance. This makes 10’6″ the normal height restriction on the step deck. This is about 2 feet of extra clearance without the need for a permit. This is an ideal choice for higher shipments such as tractors, different types of machinery, and anything that’s over 9′ tall.
