Difference Between RGN trailer and Lowboy Trailer

1. Definition

1.1 What is a RGN trailer?

A RGN trailer, which stands for Removable Gooseneck trailer, is a type of specialized flatbed trailer commonly used in the transportation industry. What sets an RGN trailer apart is its unique design that allows the front end (the gooseneck) to be detached or removed. This feature makes it easier to load and unload heavy equipment onto the trailer.

RGN trailers are particularly well-suited for transporting tall or oversized cargo, such as construction machinery, industrial equipment, and other large items that might be difficult to load onto a standard flatbed trailer. By detaching the gooseneck, the front of the trailer can be lowered to the ground, creating a ramp for equipment to be driven or rolled onto the trailer.

1.2. What is lowboy semi trailer?

A lowboy trailer is a type of heavy-duty trailer commonly used in the transportation of tall or oversized cargo, particularly heavy machinery and equipment. It is characterized by its low deck height, which allows it to carry tall loads while still maintaining stability and balance.

2 Important

2.1 Important Benefits with an RGN trailer

1. Ease of Loading and Unloading: The detachable gooseneck feature allows the front of the trailer to be lowered to the ground, creating a ramp. This makes it significantly easier to load and unload heavy equipment compared to traditional flatbed trailers.

Versatility: RGN trailers are highly versatile and can handle a wide range of cargo, including tall or oversized items. This makes them suitable for industries like construction, agriculture, and manufacturing.

2. Safe Transport: The design of an RGN trailer provides stability and balance, which is crucial when transporting heavy equipment. The low-angle loading ramp minimizes the risk of accidents during the loading and unloading process.

3.2 Design of RGN trailer and lowboy trailer

The designs of RGN (Removable Gooseneck) and lowboy trailers are specialized to cater to the transportation of heavy and oversized equipment. Here are the key features and designs of both types:

RGN Trailer (Removable Gooseneck):

Gooseneck Section:

The defining feature of an RGN trailer is the detachable gooseneck section. This is the front part of the trailer that can be disconnected from the main deck.

The gooseneck typically has a hydraulic mechanism to allow it to be raised or lowered, creating a ramp for loading and unloading heavy equipment.

Main Deck:

The main deck is the flat surface of the trailer that extends from behind the gooseneck to the rear of the trailer.

It is designed to be wide and flat to accommodate various types of cargo.

Drop Decks:

Some RGN trailers have drop decks, which are lower sections of the trailer located after the gooseneck and before the wheels. These drops allow for additional clearance for tall equipment.

Ramps and Load Securement Points:

RGN trailers often have built-in ramps that can be deployed to assist with loading and unloading.

They are equipped with multiple tie-down points and securement options to safely fasten cargo during transit.

Lowboy Trailer:

Low Deck Height:

A defining feature of a lowboy trailer is its low deck height, achieved through drops in the deck just after the gooseneck and before the wheels.

This low profile allows for the transportation of tall equipment while maintaining stability.

Unlike an RGN trailer, a lowboy trailer does not have a detachable gooseneck. The gooseneck is a permanent part of the trailer’s structure.

Main Deck:

Similar to an RGN trailer, the main deck is the flat surface of the trailer that extends from behind the gooseneck to the rear of the trailer.

Loading Ramps:

Some lowboy trailers may have removable or folding loading ramps that can be deployed to assist with loading and unloading.

Tie-Down Points and Securement:

Like RGN trailers, lowboy trailers are equipped with multiple tie-down points and securement options to safely fasten cargo during transit.

Axles and Suspension:

Lowboy trailers often have multiple axles to distribute the weight of heavy loads evenly. They may also have air suspension systems for added stability and smooth rides. air suspension flatbed trailer

Understanding when to choose a lowboy trailer over an RGN trailer is crucial for making the right purchasing decision tailored to your specific needs. These two trailer types exhibit notable differences that necessitate careful consideration.

Both options are well-suited for those with concerns regarding cargo weight and height. However, when it comes to maximizing capacity in these aspects, the RGN trailer stands out as the superior choice.

Opting for an RGN trailer offers the advantage of effortless cargo loading, thanks to its detachable and lowerable configuration. In this lowered position, self-powered cargo like construction equipment can be driven onto the trailer before reattachment, a feature not available with a lowboy trailer.

In summary, the selection between an RGN trailer and a lowboy trailer is intricately tied to functionality and cost. It’s essential to weigh these factors carefully to make an informed choice that aligns with your specific transportation requirements.
