What Is a Drop Deck Trailer?

The term “drop deck trailer” can mean two very different things depending on who’s talking. Whether you're in construction, freight, or rentals, it's important to understand the distinction-because while they share a name, these trailers serve completely different purposes.

Two Trailers, One Name

When someone says “drop deck trailer,” they could be referring to one of two types:

1. Hydraulic Drop Deck Trailer – A trailer that physically lowers its deck to the ground using a hydraulic system.

   
   

   

   
   

2. Step Deck Trailer – A flatbed trailer with a lower main deck designed to haul taller freight while staying within legal height limits.

   
   

   

   
   
   
   

Both technically “drop” in height-but beyond that, they’re entirely different tools.

Hydraulic Drop Deck Trailers (What Drop Deck Direct Specializes In)

A hydraulic drop deck trailer is built for ground-level loading. At Drop Deck Direct, our trailers use a two-piece system: the deck rests inside the chassis on sealed bearings and is raised/lowered using a hydraulic cylinder powered by a 12V onboard battery.

When lowered, the deck sits flush with the ground, eliminating the need for ramps. That makes it ideal for transporting low-clearance, wheeled equipment such as:

• Scissor lift

• Forklifts

• Floor scrubbers

• Compact construction equipment

  
  

They’re widely used by plumbers, HVAC and electrical contractors, municipalities, and rental companies-especially in environments where safe, efficient loading is a daily necessity.

Step Deck Trailers (Also Called Drop Decks)

A step deck trailer, sometimes referred to as a “drop deck” in freight circles, is a type of flatbed trailer designed to accommodate taller cargo.

It has two fixed deck heights:

• A higher front deck (above the tractor's fifth wheel)

• A lower main deck for taller loads

  
  

This design allows freight haulers to legally carry loads that exceed the height limit of a standard flatbed. However, it does not lower to the ground and requires ramps, loading docks, or a side load from a forklift.

Step deck trailers are commonly used for:

• Crated equipment

• Industrial materials

• Over-height freight

• Machinery transported by CDL operators

  
  

Why the Confusion?

Because both trailer types have decks that are “dropped” compared to traditional trailer configurations, the term “drop deck” has stuck for both.

• In construction and equipment circles, drop deck usually refers to a hydraulic trailer that lowers to the ground.

  
  

• In freight and logistics, drop deck often means a step deck trailer used for hauling tall loads.

  
  

Knowing which is which helps avoid miscommunication-especially when ordering, quoting, or searching online.

Final Thoughts

So, what is a drop deck trailer? It depends on the industry.

• In construction and equipment hauling: it's a hydraulic trailer that drops to the ground for easy, safe loading.

• In freight: it's a step deck flatbed used to haul tall cargo without exceeding legal height limits.

  
  

They’re both valid uses of the term-but they’re built for very different jobs.

If you're looking for trailers that lower all the way to the ground, you're looking for a hydraulic drop deck trailer-and that’s what we do at Drop Deck Direct.
