The Difference in Dimensions Between a Lowboy and RGN Trailer

Lowboy trailers and RGN trailers are two of the most common types used to transport oversized loads. While a lowboy trailer can be an RGN, not all RGN trailers are lowboys.

So what’s the difference? And which one should you use to ship your heavy equipment?

Consulting a logistics agent at Heavy Haulers is the best way to determine which trailer best suits your shipping needs. However, knowledge is power; understanding equipment transport will serve you well.

Let’s discuss the distinctions between a lowboy trailer and an RGN trailer, along with their dimensions and optimal uses.

What is a Lowboy Trailer?

A lowboy trailer is ideal for shipping loads that exceed height limits. Also known as a double-drop, low-bed, float, or low-loader trailer, this commercial trailer remains low to the ground, helping to avoid extra permits and allowing clearance under bridges or powerlines, where standard-height trailers would not suffice.

• A lowboy trailer with two axles can accommodate a maximum freight weight of up to X pounds; if it has extra axles, this capacity can increase.
• The maximum well length is between 24 to 29.6 feet.
• The maximum well height is between 18 to 29.6 inches.
• A lowboy trailer can handle a maximum legal width of 8.5 feet.
• Its legal freight height ranges from 11.5 to 12 feet.

Understanding the legal dimensions of lowboy trailers will help you gauge what types of loads you can haul, avoiding fines and delays.

What is a Removable Gooseneck (RGN) Trailer?

Removable gooseneck (RGN) trailers feature a detachable neck, allowing the trailer to drop and function as a ramp. This design is perfect for transporting drivable equipment like excavators and wheel loaders, as well as mining and farm machinery.

RGN trailers can accommodate additional axles for carrying heavier loads.

The maximum dimensions of an RGN trailer are as follows:

• Maximum well length: 29 ft.
• Maximum well width: 8.5 ft.
• Maximum legal freight height: 11.6 ft.
• Maximum freight weight: up to X pounds.

Which Trailer Should I Use To Transport My Oversize Load?

The choice between RGN and lowboy trailers depends on your specific needs. Lowboy trailers come with RGN options and are widely used due to their versatility.

An equipment transport doesn't need to be over-height to justify using a lowboy; it could be overweight or over-width. Due to the RGN features, lowboy trailers allow for easy equipment loading.

Lowboy Vs RGNs: What's The Difference For Heavy Duty ...

Selecting the right trailer for transporting oversized freight is crucial. Lowboy and removable gooseneck (RGN) trailers provide significant advantages, featuring essential differences that haulers should note. Below, we offer a brief overview of both trailer types and highlight some of our available models. Read on to learn more!

Hauling Capacities

A key difference between RGN and lowboy trailers lies in loading functionality and hauling capacity. A two-axle double-drop lowboy trailer can support up to 48,000 pounds, with the option to double this capacity by adding extra axles. The double-drop well typically ranges from 24 to 29.6 feet, making these trailers suitable for equipment like bulldozers and heavy machinery. The standard RGN configuration includes:

• Tri-axle to support up to 55,000 lbs
• Fixed neck
• 29.6 ft well

RGN trailers can be configured for up to 150,000 pounds or more across multiple axles, with a main deck length usually at 29.6 feet, making them ideal for cranes and implements. The standard RGN setup includes:

• Tandem axle to support up to 48,000 lbs
• 29.6 ft well

RGN Unique Feature: Ramp Loading

When transporting heavy freight common to semi-trailers, one of the most significant advantages of RGNs is their ramp-loading capability. RGNs can be lowered to create a large ramp, allowing vehicles or equipment to be driven directly onto the trailer using the hydraulic-powers gooseneck. This ramp feature eliminates the need for additional equipment such as cranes or lifts.

Lowboy Ins and Outs

Fixed-neck lowboys, as the name suggests, do not have a removable gooseneck and are generally lighter, allowing for higher load capacity. They can be loaded from both the side and rear. Lowboys are commonly used in industries such as Oil & Gas, Agriculture, and Construction.

Ultimately, your decision to purchase a standard lowboy or RGN trailer will depend on your carrying capacity, loading requirements, and budget.
