Double Drop Deck/Lowboy Transport Services
The movement of oversized equipment, heavy machinery, and tall freight that exceeds standard shipping dimensions is critical across industries like construction, energy, mining, manufacturing, aerospace, and agriculture.
A double drop deck trailer (also known as a lowboy trailer) is specifically designed to transport these oversized and overweight loads safely and efficiently.
As one of the nation’s leading heavy equipment transportation brokers, we specialize in arranging complex double drop trailer shipments that other providers consider difficult, unique, or even impossible.
What Is a Double Drop Trailer?
A double drop deck trailer (also called a lowboy trailer) is a specialized flatbed trailer designed to haul oversized and heavy freight. It features a deck that drops below a truck’s axle height, giving it a lower center of gravity and greater vertical clearance for cargo. This design allows for the hauling of larger and taller loads that would be impossible to transport on a standard flatbed.
The trailer’s deck has two drops, creating three distinct sections: an upper deck at standard height, a lower middle deck that sits closer to the ground, and a rear upper deck. Double drop trailers typically range from 48 to 53 feet in length, with a weight capacity of 35 to over 50 tons, and the cargo bed can sit as low as just 18 inches off the ground.
This low-profile design distinguishes double drop trailers from both standard flatbed trailers (single-level deck) and step deck trailers (two-level deck), making them the go-to choice for the tallest and heaviest loads.
How Double Drop Trailers Compare to Other Trailers
| Feature | Double Drop Trailer | Step Deck Trailer | Flatbed Trailer |
| Deck Height | Extremely low (lowest being middle deck) | Low but slightly higher than double drop | Standard flat deck height |
| Best For | Tall and heavy oversized loads needing extra clearance | Heavy loads not necessarily tall | General cargo, crates, and palletized loads |
| Center of Gravity | Lowest — offers maximum stability | Low — good for heavy loads | Higher — standard palletized loads |
| Ease of Loading | Very easy for tall loads; low deck and built-in ramps | Easy, often with hydraulic ramps | Easy for pallets at loading bays; not suitable for oversized equipment |
| Weight Capacity | High — handles very heavy loads | Very high — built for extreme weights | Moderate |
| Permit Needs | Often required for oversized loads | Required for extreme weights | Fewer permits needed |
Advantages of Double Drop Trailer Shipping
Enhanced Cargo Capacity
Multiple pieces of varying sizes can often be consolidated onto a single shipment. For example, a highway construction project may transport an excavator, cable drums, and structural beams on one load.
Simplified Loading & Unloading
The low deck height allows for easier loading using cranes or forklifts. Extremely heavy machinery — even 40+ ton units — can be positioned more efficiently than on a traditional flatbed.
Increased Safety & Stability
The lower center of gravity significantly reduces the risk of shifting or tipping during transit. This is especially critical for tall loads like wind turbine gearboxes or large industrial equipment.
Ability to Move Oversized & Tall Loads
The double drop design allows freight that exceeds standard height limits to be transported more safely and legally with proper permitting. The maximum legal freight height in the US is 14 feet, though permissible limits may vary by jurisdiction.
