What is a flatbed trailer?
Flatbed trailer is a kind of open transportation means, neither side wall nor top, specially used for transporting those large and irregular goods. It is especially suited to transporting heavy items like steel, machinery and equipment, and wind turbine blades. Flatbed trailers are easy to maneuver because they can be loaded and unloaded from all sides.
Flatbed trailers easily handle oversized or overweight loads, reducing the number of transports and helping you save time and costs. No matter which country they are used in, GENRON’s flatbed trailers are built to comply with local transportation regulations, ensuring that the transportation process is both efficient and safe. For truckers and logistics companies, it is a must-have tool in the freight transportation industry.
Types of flatbed trailers and their functions
Standard Flatbed Trailers
A standard flatbed trailer is a good choice if you regularly transport construction materials, pipes, or produce. It is usually 48 to 53 feet long and 8.5 feet wide, making it perfect for most regular transportation tasks. With a carrying capacity that usually ranges from 48,000 to 52,000 pounds, it offers stability and reliability, making it the best basic model for everyday transportation.
Step Trailers (Drop-Thru)
This trailer is especially suited for transporting tall items such as heavy machinery and steel structures. It has a two deck design with a low bottom deck. Typically, a step-down trailer has a lower deck height of 3.6 feet and can carry up to 10 feet of cargo. It provides more vertical space for taller items and ensures that they can be transported safely.
Retractable Flatbed Trailer
The retractable flatbed trailer is ideal for situations where extra-long cargo needs to be transported. Its main deck can be extended on demand to a maximum length of 80 feet. This design makes it particularly suitable for the transportation of wind turbine blades, bridge components and other extra-long items. Need a special design for transportation? An extendable flatbed trailer can meet your needs.
Low Chassis Trailer (Dual Trailer)
Designed with a body very close to the ground, the Low Chassis Trailer is specially designed for the transportation of extra tall cargo. Its exceptionally low design allows it to easily pass over most bridges and tunnels, avoiding transportation obstacles caused by height restrictions. Common cargoes include heavy machinery, construction equipment and over-height cargoes.
Conestoga Trailer (Side Curtain)
The Conestoga trailer is perfect for cargo that needs to be protected. It is equipped with a sliding tarp system that prevents damage to the cargo from dust, rain and other weather elements. It is ideal for transporting delicate equipment, sensitive materials, and other cargo that requires special protection.

Flatbed trailer dimensions and laws and regulations
Flatbed Trailer Standards and Scalability
Standard flatbed trailers typically measure 48-53 feet in length, 8.5 feet in width, 5 feet in height, and can carry up to 52,000 pounds. These trailers can efficiently transport various types of construction materials such as steel and lumber. For extra-long loads, it is recommended to choose an expandable flatbed trailer that can extend up to 80 feet in length, making it ideal for large projects or special transportation needs.
U.S. Transportation Regulations
In the United States, for example, there are a number of transportation regulations in place to avoid oversized shipments.
Maximum height: 13 feet 6 inches (4.1 meters), which is not only the standard highway limit, but also the height limit for most tunnels and bridges.
Maximum Width: 8.5 feet to ensure no conflicts with traffic signs and infrastructure.
Maximum GVWR: 80,000 lbs (36,287 kg) with loads not to exceed 20,000 lbs on one axle and 34,000 lbs on two axles.
If the size or weight of the goods you are transporting exceeds these limits, you will need to apply for a Special Transportation Permit, especially if transporting across state lines. And if you’re transporting over-height cargo, then using a lowboy trailer is a good option for compliance and can help avoid violations and transportation delays.
Best Practices for Securing Cargo
Cargo securing tools
Chains: For heavy cargo, chains are the most reliable securing tool. Ensure that chains are securely fastened when sufficient pressure is applied.
Straps: For lighter and more easily deformed cargo, such as wood or plastic pipe, adjust the tightness of the straps to ensure the cargo is stabilized.
Coil holders: Ensure that long or round cargoes do not slide, especially when transporting steel pipes, metal coils, coil holders are essential.
Padding: Use rubber pads or wooden boards to increase friction and prevent cargo from moving during transportation.
Loading Tips
Heavy loads first: Ensure that heavy loads are placed at the bottom of the trailer and as close to the front as possible to help balance and minimize unwanted leaning.
Distribute cargo evenly: Both light and heavy cargo should be evenly distributed across the entire platform of the trailer to avoid unstable transportation caused by uneven weight.
Protective Measures
Use tarpaulins to cover the cargo: Avoid the effects of bad weather on the cargo, especially when transporting sensitive items, tarpaulins can provide effective protection.
