Used Lowboy Trailers For Sale in Colorado

Used lowboy trailers are built for hauling tall, heavy equipment that cannot ride legally or safely on a standard flatbed. In Colorado, that usually means construction machinery, paving equipment, crushers, ag tractors, and specialized loads moving through mountain corridors, oilfield routes, and municipal job sites. A lowboy trailer, also called a low-bed or double-drop heavy haul trailer, gives you deck height where it matters most. The key buying decision is not just rated tonnage. It is how the trailer is configured for the freight you actually move, including well length, neck style, axle count, ride height, and deck accessories.

Most buyers start with capacity and loading method. Common used lowboy trailers in this class run from roughly 35 ton to 60 ton, with tri-axle layouts, lift axles, and flip axle capability showing up often. Hydraulic removable gooseneck trailers are popular because they let you drive equipment on from the front, which is a major advantage for tracked machines, pavers, and other low-clearance equipment. Fixed neck lowboys can be simpler and lighter, and they often make sense for buyers who load from the rear with ramps and keep freight more consistent. Pay close attention to well length, usually around 24 to 26 feet in many general construction setups, because that dimension determines how well a dozer, excavator, or loader will balance across the deck and axles.

Specs matter on a lowboy because small differences affect permits, loading time, and tire wear. Buyers should look at kingpin settings, overall deck length, 102-inch width, tire size, suspension type, and whether the trailer has adjustable ride height. Air ride suspension is common and helps with load stability and deck control, especially when terrain and job sites vary. Features like outriggers, D-rings, load-bearing fenders, boom troughs, bucket wells, traction cleats, tool trays, and strobe lights add real operating value when you are securing mixed equipment or running oversize loads. In heavier configurations, a rear lift axle, flip axle, or spreader bar can make the difference between a practical legal payload and a trailer that is too limited for regional heavy haul work.

On a used lowboy trailer, condition inspection is as important as the spec sheet. Check the neck structure, deck crossmembers, ramp hinges, hydraulic system, pony motor or PTO hookups, suspension components, and frame alignment. Look closely at wood decking, tire condition, brake wear, and signs of stress around axle connections and load concentration points. For Colorado operators, it also pays to think about how the trailer will behave on grades, in winter conditions, and on uneven access roads. The right used lowboy should match your freight profile first, then your permit strategy, tractor setup, and maintenance expectations. A well-matched trailer will load faster, carry more efficiently, and stay productive across a wide range of heavy haul jobs.
