FRANCIS SCOTT KEY BRIDGE IMPACT

Watching the video of the bridge collapse was surreal. To have that structure there one minute, then five seconds later be completely gone, was jaw-dropping. Certainly, our thoughts and prayers are with those whose lives were impacted by the collapse.  

Since the incident, clean-up has begun and a temporary waterway has been established, but it will take a while for the port to fully recover, let alone the bridge itself to be rebuilt. While the 30,000 plus vehicles that regularly cross that bridge is a sizable number, it’s about one-sixth of the volume that uses nearby major thoroughfares like I-695 or I-95 in the Baltimore area. Still, that traffic will need to go somewhere.  

From the trucking side, there will likely be two main areas of impact. First, local freight that is destined for ocean travel will now need to find another port of departure, likely destinations the ports of NJ/NY; Philadelphia; and Norfolk, VA. This means more freight will be heading out of the Baltimore area.  

Figure 1.1 below shows that since the end of March, right around the time of the bridge collapse, outbound volume, and freight tender rejection rates, have trended upward. Second, freight that travels around the Baltimore area will likely incur more out of “normal” route miles if the bridge was part of its route. 

More carrier miles = more time to deliver = less time for other freight = increased freight costs.

SOME BALANCE SEEN

Overall, freight volumes have trended slightly above 2023 (Figure 2.1).  

This has not dramatically impacted freight rates nationally or freight tender rejection rates. Excess capacity continues its slow runoff, and March saw an uptick in for hire carriers.  

On a more granular scale, flatbed freight seems to be more optimistic. As seasonal flatbed type freight, combined with an uptick in industrial production and manufacturing activity is occurring, it has pushed flatbed rejection rates to more normal levels over the past few months as seen in Figure 3.1.  

Flatbed rejection rates reached their highest point in over a year recently, and a 15 percent rejection rate is indicative of a more balanced freight market, if only for a certain equipment type segment.

Whether it’s lumber, piping, hay, palletized goods, or construction supplies, flatbed trailers, also known as open-deck trailers, can handle it all. Flatbed trailers are extremely versatile in their use, but that’s because, unlike enclosed trailers, there are many variations of flatbeds to choose from. If you’re considering a flatbed or open-deck trailer for your shipment, how do you know which one is best for your freight? This article will help you answer just that. Read on to better understand the different kinds of flatbed trailers that are available so you can make an informed decision on which one your freight needs.

Types of Flatbed Trailers

Flatbed trailers come in all shapes, sizes, and load capacities; each designed to carry different types of cargo. The one tricky part of flatbed shipping is choosing and finding the flatbed trailer that is capable of hauling your freight’s weight and size. It’s also important to note that anything exceeding legal dimensions and weight can be considered oversized and may require more to ship, such as state permits, police, escorts, or more.

*Important Note – Trailer capacity, weight, and dimensions mentioned in this article are general specifications and should be used as an estimated guideline. These can vary based on the trailer type, brand, or semi-tractor being used with it.  

• Standard flatbed
• Extendable flatbed
• Step deck / drop deck
• Stretch single step deck / drop deck
• Double drop
• Stretch / extendable double drop
• Removable gooseneck (RGN)
• Stretch RGN
• Conestoga
• Side kit

Standard Flatbed Trailers

Maximum Legal Weight: 48,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft. 6 in.

Standard flatbed trailers are widely used and versatile, often the most popular of all flatbed trailers. They most commonly haul steel, lumber, and other kinds of building or construction materials.

Extendable Flatbed Trailers

Maximum Legal Weight: 43,000 lbs.

Maximum Legal Cargo Length: 48 to 80 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft. 6 in.

Extendable flatbed trailers can also be known as flatbed stretch trailers. These trailers have an extendable deck to transport cargo that is too long for a standard flatbed, like a piece of large or heavy machinery. 

Step Deck/ Drop Deck Flatbed Trailers

Maximum Legal Weight: 48,000 lbs.

Top Deck: Maximum Legal Cargo Length: 11 ft.

Bottom Deck: Maximum Legal Cargo Length: 37 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 10 ft. on the bottom deck, 8 ft 6 in. on the top deck

These trailers are referred to as either a step deck or a drop deck. They consist of a bottom deck and a top deck. These flatbed trailers are great for transporting freight that would exceed the height restriction on a standard flatbed; they are ideal for any tall loads that need to go under low bridges. They also make it easy to use ramps to load and unload freight. A common piece of freight they haul is tractors. 

Stretch Single Step Deck/Drop Deck Flatbed Trailers

Maximum Legal Weight: 45,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 35 to 63 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck: Maximum Legal Height: 10 ft.

These flatbed trailers are like step decks, except they can be extended to transport cargo that can be too long for a standard step deck. This can include goods like scaffolding or drilling and mining equipment. 

Double Drop Flatbed Trailers

Maximum Legal Weight: 36,000 to 40,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck (well): Maximum Legal Cargo Length: 25 to 29 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

Double drop trailers are also good for cargo that is too tall and generally used to haul oversized freight. Double drop trailers are unique in that they have a longer piece of the trailer called the “well”.

Stretch/Extendable Double Drop Flatbed Trailers

Maximum Legal Weight: 40,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck (well): Maximum Legal Cargo Length: 29 to 50 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

Like the standard double drop trailer, this one is also great for oversized freight. Since this trailer can be lengthened for longer loads, it’s ideal to carrier longer freight since it provides more support and prevents any overhang. It’s also common for this trailer to have two to three axles so it can support more weight. Common freight hauled by stretch double drops are pipes and steel beams.

Removable Gooseneck (RGN) Flatbed Trailers

Maximum Legal Weight: 42,000 to 150,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 30 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

An RGN is one special flatbed trailer. They’re great for long, tall, and heavy freight! They have a detachable front that can be used to create a ramp for loading and unloading and can expand from three axles to over 20, to carry heavy items, like farming combines. However, it’s important to note that since these are more specialized, they can be tougher to find and more expensive to use for your flatbed shipping.

Stretch RGN Flatbed Trailers

Maximum Legal Weight: 42,000 to 150,000 lbs.

Front Deck: Maximum Legal Cargo Length: 10 ft.

Main Deck: Maximum Legal Cargo Length: 29 to 65 ft.

Rear Deck: Maximum Legal Cargo Length: 9 ft.

Maximum Legal Width: 8 ft. 6 in.

Front Deck: Maximum Legal Height: 8 ft. 6 in.

Main Deck (well): Maximum Legal Height: 11 ft. 6 in.

Rear Deck: Maximum Legal Height: 10 ft.

When you need an RGN that can haul longer freight, a stretch or extendable RGN can help. Just like the standard RGN, axles can vary, from three and up, depending on the freight weight. The only real difference with this RGN trailer is the main deck is extendable up to 65 feet long.

Conestoga Flatbed Trailers

 Maximum Legal Weight: 42,000 to 45,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 6 in.

Maximum Legal Height: 8 ft.

One interesting fact about Conestoga trailers is that Conestoga is also a brand name for them. Conestogas are specialized, flatbed trailers that have a hard shell and rolling tarp system, which is great for freight that needs better protection from outside elements. These can be one of the most requested flatbed trailers due to their versatility. They can often be seen transporting freight like CNC machinery or helicopters.

Side Kit Flatbed Trailers

Maximum Legal Weight: 42,000 to 45,000 lbs.

Maximum Legal Cargo Length: 48 to 53 ft.

Maximum Legal Width: 8 ft. 4 in.

Maximum Legal Height: “technically” it’s 8 ft. 6 in. but because of sides, 6 ft. is more easily accomplished

Side kit trailers are like Conestogas in that they are flatbed trailers that offer more protection. These trailers have panels surrounding often made from plywood or fiberglass, allowing for tarping over the top. Side kits are great for freight that is not packaged or crated, like corn or watermelons.

Flatbed Trailer Tips

Match Your Cargo to the Correct Flatbed Trailer

It’s important to know your cargo and that you have the right flatbed trailer to transport it. If the wrong trailer pulls in and it can’t carry your freight, you’ve lost out on precious travel time. Additionally, having the correct trailer ensures safe transport.

Communicate the Details

Regardless of what kind of product you need to transport, a lack of detailed communication with your logistics provider is important to avoid confusion and setbacks. For a logistics provider to effectively support you with your flatbed shipping needs, you’ll need to share specific details such as:

• Dimensions of cargo (length, width, height)
• Cargo weight
• Type of commodity
• Does your freight have any sharp edges?
• Does it need tarped/element protection?
• Is your cargo multiple pieces or singular?
• Is your cargo loose or palletized?

Understanding Your Flatbed Trailer Needs

Understanding the different kinds of flatbed trailers there are helps you make more informed and cost-effective decisions. You’ll better know their limitations and whether they may be more costly and time-consuming to acquire. For example, by knowing that more specialized flatbed trailers like RGNs or Conestogas are tougher to obtain, you’ll know to give your logistics provider advanced notice for those shipments, giving you the benefit of a more successful relationship and potentially cheaper rates.
