RGN (Removable Gooseneck) and Heavy Haul trailers are specialized types of trailers designed to transport oversized, overweight, or uniquely shaped loads. Here’s what they typically carry:

RGN (Removable Gooseneck) Trailers

RGN trailers have a detachable front that allows the trailer to be lowered to the ground for easy loading and unloading of large, heavy equipment.

1. Heavy Machinery:
   • Construction equipment (excavators, bulldozers, loaders, cranes)
   • Agricultural machinery (tractors, harvesters, plows)
   • Mining equipment
2. Vehicles:
   • Large trucks and buses
   • Military vehicles
   • Specialty vehicles (fire trucks, ambulances)
3. Industrial Equipment:
   • Large tanks and pressure vessels
   • Industrial boilers
   • Generators and turbines
4. Prefabricated Structures:
   • Modular buildings and houses
   • Large metal or concrete components for construction
5. Miscellaneous:
   • Large spools of cable or wire
   • Wind turbine components
   • Oversized pipes and beams

Heavy Haul Trailers

Heavy haul trailers are designed to transport extremely heavy and oversized loads that exceed the standard legal size and weight limits.

1. Super Heavy Machinery:
   • Massive mining equipment
   • Offshore drilling rigs
   • Large industrial presses and machinery
2. Construction and Infrastructure:
   • Bridge components
   • Large concrete beams and girders
   • Heavy-duty cranes and tower sections
3. Power Generation Equipment:
   • Large transformers and substations
   • Power plant components
   • Wind turbine blades and nacelles
4. Special Projects:
   • Spacecraft components
   • Large sculptures and art installations
   • Oversized tanks and silos
5. Marine and Aerospace:
   • Large boats and yachts
   • Aircraft parts and fuselages

Both RGN and heavy haul trailers are critical in industries that require the transportation of large and heavy items that cannot be divided into smaller loads. They often require specialized handling, routing, and permits due to their size and weight.

Step deck trailers (also known as “drop deck trailers”) are designed to carry loads that are too tall for standard flatbeds but don’t require the full height of a lowboy or RGN. They have a lower deck (the “step”) that makes it easier to transport taller items while still maintaining a lower overall height. Here are some common types of content transported on step deck trailers:

1. Construction Equipment:

• Excavators, bulldozers, and backhoes
• Skid steers and compact loaders
• Heavy machinery and attachments

2. Oversized Cargo:

• Large or tall equipment that exceeds the height restrictions of standard flatbeds
• Machinery components with significant vertical height

3. Building Materials:

• Steel beams, columns, and structural components
• Prefabricated building panels and modules
• Heavy construction materials like large concrete blocks or slabs

4. Agricultural Equipment:

• Combines, plows, and large tractors
• Harvesters and other large farm equipment

5. Industrial Equipment:

• Large tanks and vessels
• Heavy-duty generators and transformers
• Industrial fans and pumps

6. Miscellaneous Items:

• Large or tall vehicles, such as RVs or specialty trucks
• Wind turbine components (blades and towers) that are not excessively tall
• Pre-assembled structures or components for large-scale projects

Step deck trailers are versatile and can handle a variety of loads that are taller than what a standard flatbed can accommodate but still require more height flexibility than a traditional lowboy. They often have a rear deck that can be loaded with standard-sized cargo or equipment, making them suitable for a range of transport needs.
