Premier has over 100 specialized trailers to meet your shipping needs. All trailers have air ride suspension, are in top condition, and are inspected regularly for maximum safety and reliability. Here are some examples.

“Premier's service and equipment are second to none in the field of specialized transportation.”

These are the lightest and most common of open style trailers on the road. They are also the tallest and can only handle freight approximately 8 feet tall. Premier maintains a small number of these trailers to use when required, but the height of our cargo usually calls for a single or double drop.



Typical cargo weight allowed: 44,000 to 46,000 pounds

Single Drops:
This is our most commonly used trailer. They are relatively lightweight (allowing more cargo capacity), can transport cargo approximately 10 feet tall, and still have approximately 37 feet of straight deck. These trailers are typically 42″ in height but Premier has many at 36″ height. The spread axles help distribute cargo weight more evenly.
The majority of these trailers are 48’ in length as shown, but Premier also has 53’ trailers when needed. Premier has both steel and aluminum single drops; with the aluminum trailers being lighter and allowing for more cargo weight.




Typical cargo weight allowed: 40,000 to 45,000 pounds

Did You Know?

The length of time to stop an eighteen wheeler is 40% greater than that of an automobile. Depending on the weight of their load, whether they are bobtailing, road conditions, and other factors. To be sure, it takes a much greater time to stop than an automobile. Trucks only have 10 brakes NOT eighteen. Recently manufactured trucks are now required to have anti-lock brakes.



“Over the past 10 years, Premier has been our #1 choice because they perform, as planned, every time, and at a reasonable cost. No other carrier compares.”

“Reliability is the main reason why we use Premier.  We shipped over 150 machines with them in 2006, and never had a damaged machine.  All machines arrived on time and when promised.  With Premier, I never have to worry! “

Double Drops:
Double drops are used for taller cargo, generally 11-12 feet tall. These trailers are heavier, more expensive, generally less versatile, and therefore less common. They will usually be 18″ high or 24″ high and have approximately 28 feet of straight deck in the middle. Some double drops can separate behind the front deck to allow vehicles such as tractors to be driven onto the trailer. These are called detachable double drops.



Typical cargo weight allowed: 40,000 to 42,000 pounds

Stretch Single Drops and Double Drops:
These trailers expand for cargo that is tall and long.


Multiple Axles :
If you have a single piece of cargo which exceeds the normal allowable weight laws, we can request a special permit for extra weight. As the gross weight increases, more axles are required to spread the weight over more of the road to avoid damaging roads and bridges. Premier operates a variety of specialized multi-axle tractors and trailers to handle shipments of 100,000 pounds and more.



Specialized Covered Trailers:
Premier operates a number of specialized covered trailers. These trailers offer some of the characteristics of a closed, van style trailer while still allowing for side loading or crane loading. These trailers are typically used for shorter regional shipments and for shipments too delicate to tarp.





FAQ Cargo Weights: How much weight can be loaded on the trailer?

The starting point to know about trailer capacities is that state and federal laws allow a load to have a GROSS weight of 80,000 pounds. Gross weight means the total weight of the tractor, trailer, tarps, cargo, etc; everything on the load. So the lighter the non-cargo portions are, the more cargo weight can be loaded before hitting the 80,000 pound limit. This rule is typically meant to apply to loads with multiple pieces on them, where the loading party has a choice of when to stop putting more pieces on.

You will see that beneath each trailer picture above (single drop, double drop, flatbed) we are showing an average range for cargo weight, not a firm number. This is because the weights of the individual tractors can vary, according to the size of the tractor and the options on it. The individual trailer weights can vary by manufacturer, by material (steel vs aluminum), by length, and by type (single drop, double drop, flatbed). The amount can also vary by the number of tarps and chains and other accessories the driver might choose to carry.

Flatbeds will typically have the lightest empty weight. This is because a flatbed is a single straight deck and supporting beams. When you create the one drop in a single drop, or the two drops in a double drop, it requires more steel and more welding to maintain the strength of the trailer. So the allowable weight capacities will typically be more for a flatbed, than a single drop, and those will both have higher capacities than a double drop. There can also be a range of individual design features which can make a big difference in the empty weights of seemingly similar trailers. Remember, when we say “capacity” here, we are referring to what the law allows for gross weight. That is different from the word to talk about the “maximum capacity” the trailer was built to haul safely.

FAQ Cargo Wights: Can a load ever exceed 80,000 pounds gross weight?

Yes, in some cases. As previously stated, you cannot exceed the 80,000 pound gross weight limit with more than one piece of cargo on the load; it must be reduced. When you have a single piece of cargo, which when put on the lightest appropriate trailer, exceeds 80,000 pounds, the law allows the carrier to apply for and purchase special overweight permits. There are additional restrictions as to how much extra weight can be permitted before changes to the trailer are required. As the single piece of cargo gets heavier, the law will require that the trailer have more axles. This is so that the additional tires can spread the extra weight more evenly on the road surface to help prevent damaged to the road and also to allow for more brakes to stop the heavier load. Any of the trailers shown can be commonly found with 3 axles instead of the normal 2. One extra axle will raise the legal gross weight limit by about 10,000 to 20,000 pounds, depending on other specifics. Special multi-axle trailers, and tractors with an extra 4th axle (also shown above), are also available for extremely heavy loads. Trailers built specifically for handling extra weight will be built heavier and are usually less practical for regular loads. It is important to remember that each individual state traveled through will require its own permit and have its own varying rules. So overweight shipments must usually be quoted on an individual basis and the cost and difficulty can vary by a number of factors. Remember again, that these overweight permits are in almost all cases only for single piece loads.
