However, not many people have clear guidance to help them choose one trailer over another. Their ability to take large cargoes leaves everyone mesmerized and excited about their function.

Here, you will get to know about two different trailer categories: the Removable Gooseneck (RGN) trailer and the Lowboy trailer. Their naming has something to do with some of their defining characteristics.

So, what exactly is the difference? Why would you choose a RGN trailer over a lowboy trailer? Here is detailed information to help you learn about the two different types of trailers.

 

1. What is a RGN trailer?

 

Removable gooseneck trailers have been around for some time. They first were introduced in the transport industry in 1958. It was all a work of design to provide a trailer with capabilities of carrying long and tall cargo.

In this design, the front part can be detached. Once the detachment has been made, it allows the trailer to be lowered to the ground. In this position, any self-powered cargo can be loaded on it.

The most common type of cargo carried on this type of trailer includes cars, heavy machinery and other trucks as would fit on it. Therefore, the detachment is useful in the loading and offloading process.

This is the most distinguishing feature of an RGN trailer from other types of trailers.  With this type of trailer, you can get one with front loading cargo, Its gooseneck is detachable.

The RGN gives you an option of adding as many axles as would fit your application. Should you want to transport much heavy load, you can add extra axles either at the rear section or to the side.

A standard 3 axles RGN trailer can take maximum freight weight of 50 tons but can be exceed with the inclusion of extra axles.

The legal maximum height is 3.5 m. However, the length and width can be designed according to your demands.

 

1.1 Important Benefits with an RGN trailer

 

Here are some of the reasons that would make you choose a removable gooseneck trailer over other types of trailers.

  • Gooseneck trailers have a tunnel underneath that can help you center your cargo with ease. Your cargo will perfectly sit on the tunnel that is usually the lowest point on the trailer. This enhances the stability of your trailer during transportation. With this set up, you can transport tall cargo with ease within the permissible legal freight height.
  • Most of the common RGN trailers have 3 axle lines. Many haulers have two axle lines even those with a design meant to take the heaviest loads that would force you to add many axle lines to find the correct configuration for heavy cargo. For the RGN 3 axle lines, you can carry a variety of loads without the need to add more axles. Should you need extra axle lines, they wouldn’t be many. With such features and capabilities, it is easy to transport the tallest and heaviest cargo without concerns over extra weight issues. These are the type of trailers you will find in construction plants. The reason is obvious because they are suitable for taking heavy construction equipment.

3. RGN vs Lowboy Trailers: Marking the Difference

 

In your choice of a trailer for your transportation, your type of cargo is very much instrumental in guiding you. You can use these characteristics to match with the list of trailers available in the market.

Here are the main differences between a lowboy and an RGN trailer:

  • Nature of Assembly. Notable characteristics of an RGN are that it can be detached from the front unlike with a lowboy trailer. This feature has been provided in an RGN to enhance loading and offloading of cargo. The user has an easy time during such occasions. This is unlike for a lowboy trailer that would need other lifting equipment to load the cargo on the trailer.
  • Weight and Height Capacity. Weight and height considerations are some of the considerations to make in your choice of a trailer. If they are a concern for you, go for an RGN trailer. It is the best type to transport cargo that is heavy and tall especially when these two parameters exceed the standard set by the law. While a lowboy trailer can help you in such occasions, RGN can take relatively higher capacity and dimensions of cargo. Again, RGN trailers are more dedicated to this function more than the lowboy trailer. For standard cargo, you can go for a lowboy trailer. However, an RGN trailer may not be an economically feasible option.
  • Cost Implications. RGN trailers are usually costly than their lowboy trailer counterparts. In that case, the choice of investing in a more specialized hauler for heavy cargo would mean spending a lot more money than when going for a lowboy trailer. The enhanced capabilities that make an RGN trailer able to take up a 70 tons cargo compared to an 40 tons cargo comes with increased cost.
  • Loading With Lowboy trailers, you cannot lower it any further. That means you can’t work without auxiliary equipment for lifting cargo and loading it onto the trailer. For that matter, it will limit you to the type of cargo that you can carry on lowboy trailers. With RGN trailers, you don’t have to be worried about this since you can almost carry all types of cargo. It is possible to carry heavy motorized machinery since the trailer can be lowered to its ramp. The appropriate trailer to choose depends on the cargo type that you want to handle. There are different types of lowboy trailers and should you shy off from the RGN trailer due to cost, go for the best lowboy trailer available in the market.

Owing to these notable characteristics, the RGN trailer is Easy to load. Ideally, the RGN trailer can load from front unlike with a lowboy trailer. This capability enhances the efficiency of the RGN trailer over that of the lowboy trailer.

You won’t have to compromise on travelling speeds because of stability issues. In the end, you will have done your transportation swiftly.
  • Number of Axles. Most of the common lowboy trailers that you will ever find in the market have two axle lines. For RGN trailers, they have 3 axle lines. There is a reason for this development: with a lowboy trailer, you may be charged for overweight or take several trips to carry all your cargo due to the number of axles. However, it is important to note that lowboy trailers can taken any cargo within the set legal freight weight hence are applicable in most industries. At times, you will have some cargo that needs special trailers and in such a case, the RGN trailers are the best option. These are the type of trailers to use in motor and construction industries. Any industry that uses heavy machinery has an extensive use of RGN trailers. This is more so due to their stability made possible by their low center of gravity. The ladder angle on an RGN trailer is far much better than that of a lowboy trailer.
  • Trailer Structure. The RGN trailer offers you with a more durable and strong structure compared to a lowboy trailer. Due to the detachable design of the gooseneck and the need for a lower working platform as provided by the RGN trailer option, high strength material with a rational design has been put in place. If you are looking for such qualities in a trailer, you got the answer with you.
