About Lowboy Trailers
Why lowboys exist
Lowboys exist because standard flatbeds can't legally haul tall equipment. The 13'6" federal height limit leaves you short on a flatbed once your equipment clears 9 feet on its own tracks or wheels. A lowboy's dropped center deck sits 18 to 24 inches off the road — half the height of a flatbed deck — which gives you clearance for tall excavators, dozers, cranes, transformers, and industrial equipment that would otherwise require a permit route or specialty hauler.

What makes ours different
Every Overbilt trailer is built by a single craftsman from frame-up through final inspection. When you're hauling 150,000 lb of equipment down a mountain grade, you want to know the welds were done right and the axles are aligned true. With Overbilt, the person who built your trailer is accountable for every detail of the build — no assembly line, no hand-off between shifts, no unsigned work.
We spec the gooseneck, the axle count, the deck height, and every custom feature around your actual equipment and your actual routes. That's how you get a lowboy that does the job for decades instead of needing a rebuild in five years.
