Lowboy / RGN Trailers
Quick Facts
- Common Type: Heavy Haul Low-Profile Trailer
- Typical Length: 24 ft – 30 ft (well), extendable options available
- Cargo Type: Extremely Heavy and Oversized Equipment
- Primary Use: Heavy Equipment and Oversize Load Transport
- Deck Height: Very Low (below standard trailer height)
- Loading Method: Detachable front (RGN) or ramps
Overview
Lowboy trailers, including Removable Gooseneck (RGN) trailers, are designed for transporting extremely heavy and oversized equipment that exceeds the capacity of standard flatbed and step deck trailers. Their low deck height allows for taller loads while maintaining legal height limits.
RGN trailers, a type of lowboy, feature a detachable front section that allows equipment to be driven directly onto the trailer, making them ideal for transporting large machinery.
Key Characteristics
Lowboy and RGN trailers are defined by their extremely low deck height, allowing them to haul tall and heavy equipment that cannot be transported on standard trailers. RGN trailers add the advantage of a detachable front, enabling drive-on loading without the need for ramps.
These trailers are commonly used in heavy haul operations where weight, height, and ease of loading are critical.
Common Specifications
Deck Height
Lowboy trailers have one of the lowest deck heights available, allowing for maximum cargo height while staying within legal limits.
Well Length
The well (main cargo area) typically ranges from 24 to 30 feet, with extendable configurations available for longer loads.
Weight Capacity
Designed for extremely heavy loads, lowboys can handle significantly higher weight capacities compared to flatbeds and step decks.
Axle Configurations
Multiple axle configurations are common, including tri-axle and multi-axle setups for heavy haul applications.
Loading Method
RGN trailers allow front loading by detaching the gooseneck, while standard lowboys may use ramps.
Types of Lowboy / RGN Trailers
- Fixed Neck Lowboy Trailers
- Removable Gooseneck (RGN) Trailers
- Extendable Lowboy Trailers
- Multi-Axle Heavy Haul Lowboys
Common Uses

• Construction equipment (excavators, bulldozers)
• Industrial machinery
• Large generators and transformers
• Agricultural equipment
• Oversized loads requiring permits
Operational Use
Advantages
Lowboy and RGN trailers provide unmatched capability for hauling extremely heavy and tall equipment.
• Lowest deck height available for maximum clearance
• Handles extremely heavy loads
• RGN allows easy drive-on loading
• Ideal for oversized and specialized freight
• Supports multi-axle configurations for weight distribution
Limitations or Drawbacks
Lowboy and RGN trailers require specialized handling, planning, and often additional permits for operation.
- Requires permits for oversized and overweight loads
- Higher operational and equipment costs
- Limited versatility compared to flatbeds
- Requires experienced drivers for safe operation
Driver and Operator Considerations
Operating lowboy and RGN trailers requires experience in heavy haul transport. Drivers must understand load securement, route planning, permit requirements, and safe loading procedures for large equipment.
Maintenance and Ownership Notes
Lowboy trailers require regular inspection of hydraulic systems (for RGN), axles, structural components, and securement points. Maintenance is critical due to the heavy loads these trailers carry.
Buying Considerations
When selecting a lowboy or RGN trailer, buyers should consider weight capacity, axle configuration, hydraulic systems, and intended equipment types. Reliability and durability are key factors.
