Heavy Haul Equipment
Perimeter Frame Trailer
Open-frame trailers that surround the cargo — for large vessels and long modules.
Designed for long, heavy cargo
A perimeter frame trailer is essentially a transport platform with the cargo in the middle and structural framing around all four sides. The frame distributes weight to axle groups at the front and rear, and the low cargo position helps with overhead clearance.
What we move on perimeter frame
- Large refinery vessels — long columns, exchangers, reactors
- Long modules — process plant skids, prefab structures
- Specific wind components — particularly long tower sections and special-class blades
Pair with
- Heavy haul permits and routing — perimeter loads usually trigger superload review
- Cranes for load and unload
Frequently asked questions
What is a perimeter frame trailer?
A perimeter frame trailer is a heavy transport configuration where the trailer frame surrounds the cargo on all four sides, with the cargo riding low (sometimes near grade) inside the frame. It's used for very long, heavy cargo — vessels and modules — where the frame distributes load across multiple axle groups front and rear.
When do I need a perimeter frame?
When the cargo is very long (40+ feet) and very heavy, and a perimeter geometry distributes weight better than a single-deck trailer. Common for large refinery columns, long vessels, and certain wind components.
