When transporting heavy machinery, oversized equipment, and tall loads, standard flatbed trailers often aren’t enough. That’s where lowboy trailers come in.

At Transport ATC, we help businesses move a wide range of heavy and specialized freight. Understanding when a lowboy trailer is needed can help ensure your shipment is transported safely, legally, and efficiently.

What Is a Lowboy Trailer?

A lowboy trailer is a specialized trailer designed to haul heavy equipment and oversized loads that exceed the height limits of standard trailers.

Unlike traditional flatbeds, lowboy trailers sit much lower to the ground. This lower deck height allows taller equipment to be transported while remaining within legal road height restrictions.

Lowboy trailers are commonly used to transport:

• Construction equipment
• Excavators
• Bulldozers
• Backhoes
• Cranes
• Agricultural machinery
• Industrial equipment
• Mining equipment

Because of their design, lowboys can handle loads that would be difficult or impossible to move on a standard trailer.

How Tall Can a Lowboy Trailer Haul?

One of the biggest advantages of a lowboy trailer is its ability to transport taller freight.

Most states limit loaded vehicle height to approximately 13’6″. Since a lowboy’s deck sits much lower than a standard flatbed, it provides additional clearance for oversized equipment.

This makes lowboys an ideal solution for moving large machinery without requiring extensive permits or alternate routes whenever possible.

How Much Weight Can a Lowboy Carry?

Lowboy trailers are built for heavy-duty transportation.

Depending on the trailer configuration, lowboys can often haul:

• 40,000 to 80,000+ pounds
• Large construction equipment
• Heavy industrial machinery
• Oversized commercial equipment

Multi-axle lowboy configurations can handle even heavier loads when required.

Common Types of Lowboy Trailers

Fixed-Neck Lowboy

A fixed-neck lowboy has a permanent connection between the trailer and the tractor.

Benefits include:

• Strong construction
• Reliable performance
• Cost-effective transportation

Removable Gooseneck (RGN)

An RGN trailer allows the front of the trailer to detach, creating a ramp for equipment to be driven directly onto the trailer.

This makes loading and unloading much easier for self-propelled equipment.

Double-Drop Lowboy

Double-drop trailers feature an extra-low center section that provides even greater height clearance for exceptionally tall freight.

Industries That Use Lowboy Trailers

Many industries rely on lowboy transportation to move critical equipment.

Construction

Construction companies regularly transport:

• Excavators
• Dozers
• Loaders
• Skid steers

Energy and Utilities

Utility and energy projects often require transportation of:

• Generators
• Transformers
• Heavy components
• Specialized equipment

Agriculture

Farm operations frequently use lowboys to move large:

• Tractors
• Harvesters
• Agricultural machinery

Manufacturing

Industrial facilities often transport oversized equipment between plants, warehouses, and project sites.

When Should You Use a Lowboy Trailer?

A lowboy trailer may be the right choice if your freight:

• Exceeds standard trailer height limitations
• Is extremely heavy
• Requires specialized loading methods
• Is oversized or irregularly shaped
• Needs additional stability during transport

Choosing the correct trailer helps reduce transportation risks and ensures compliance with state regulations.
