A detachable gooseneck trailer, often abbreviated as “RGN” (Removable Gooseneck), or “Lowboy” is a type of specialized trailer used in the transportation of heavy and oversized cargo. These trailers are commonly used in industries such as construction, oil and gas, agriculture, paving, and general heavy equipment hauling. Over the last 15 years, Kaufman Trailers has become established as a leader in the detachable gooseneck industry by offering a reliable trailer at an affordable price. Below are some key features and information about detachable gooseneck trailers:

Gooseneck Design

The distinctive feature of a detachable gooseneck trailer is its front section, known as the gooseneck, which is detachable from the main trailer deck. This design allows for easy loading and unloading of heavy equipment and oversized cargo, making it a versatile choice for transporting various types of machinery.

Detachable Mechanism

The detachable gooseneck is typically connected to the main deck using a hydraulic or mechanical mechanism. This mechanism allows the front section to be raised and detached from the main trailer, creating a ramp for loading and unloading.

Low Profile Feature

Detachable gooseneck trailers often have a low profile, which means the main deck is closer to the ground compared to other types of trailers. This low profile is beneficial when transporting tall equipment or machinery, as it provides more clearance during transportation.

Versatility of Detachable Gooseneck Trailers

Detachable gooseneck trailers can accommodate a wide range of cargo types, including construction equipment, bulldozers, excavators, cranes, wind turbine components, paving equipment, combines, tractors, military equipment, and commercial equipment. Their versatility makes them a preferred choice for transporting heavy and oversized loads.

Trailer Dimensions and Axle Configurations

These trailers come in many different lengths. Most 2-axle construction style lowboy trailers come standard with 24ft. well lengths while most 3 and 4-axle RGNs start with a little longer 26ft. well.  For the agriculture and over-the-road commercial hauling industries most detachable neck trailers have longer well lengths ranging from 29ft. to 34ft. These trailers come in various axle configurations, including multiple axles, spread axles, and removable flip axles. The choice of axle configuration depends on the specific weight and size requirements of the cargo being transported.

Load Capacity

The load capacity of detachable gooseneck trailers can vary significantly based on their design and configuration. Some models can carry loads of up to several hundred tons, making them suitable for transporting extremely heavy machinery and equipment.

Safety Features

 Detachable gooseneck trailers often come equipped with safety features such as load securement systems, outriggers, and hydraulic controls for precise positioning during loading and unloading.

Transport Regulations

Transporting oversized and heavy loads using detachable gooseneck trailers may require special permits and compliance with transportation regulations. The exact requirements vary by state or region and the size of the cargo being transported.


Proper maintenance is crucial to ensure the safe operation of detachable gooseneck trailers. Regular inspections of hydraulic systems, brakes, tires, and other components are necessary to prevent accidents and equipment failure.


Detachable gooseneck trailers are typically more expensive than standard trailers due to their specialized design and features. However, their ability to handle a wide range of heavy and oversized cargo justifies the cost for many industries.
