Fontaine Lowboy Trailers For Sale

Fontaine lowboy trailers are built for heavy equipment hauling where deck height, legal payload, and loading efficiency matter more than anything else. In this category, buyers will usually be looking at detachable gooseneck configurations, often hydraulic detachable necks, with low deck heights around 18 inches loaded and 102-inch overall width. That combination makes a Fontaine lowboy a strong fit for moving excavators, dozers, pavers, crushers, and other tall or concentrated-weight machines that need to stay as low as possible for bridge clearance and legal routing.

A lot of the buying decision comes down to capacity and configuration. Common Fontaine lowboy setups in this class include 55 ton designs with a 26-foot main deck, tri-axle bogies, air ride suspension, and compatibility with flip axles, spreader bars, or flip boxes to increase capacity or fine-tune axle groupings for state regulations. Buyers should pay close attention to weight rating in a defined deck length, not just the headline tonnage. A trailer rated at 55 tons in 10 feet or 13 feet can perform very differently depending on the machine’s track length, center of gravity, and point loading. Swing clearance, kingpin settings, axle spread, and ride height adjustment also matter if the trailer will see mixed freight or regional permit work.

Fontaine Magnitude lowboys are especially common in heavy haul fleets because they are designed around modularity. Rear connections for close-coupled flip axles, 3+1 spreader configurations, and front flip boxes give an operator more flexibility as payloads change. Features often found on these trailers include full outriggers, chain slots, multiple D-ring tie-down points, boom wells, bucket wells, lockable tool storage, manual front ramps, and aluminum outer wheels paired with steel inners. For a buyer, those details are not cosmetic. They affect how easily the trailer can secure irregular equipment, accommodate over-width attachments, and keep downtime low in daily use.

Condition and intended use should drive the final choice. A fleet focused on legal construction equipment moves may prefer a straightforward 3-axle fixed rear setup with air lift on one axle, while a carrier handling heavier permitted loads may need flip axle compatibility from day one. Check deck length, ground clearance, neck style, suspension brand, and empty weight carefully, because every added option changes payload margin and permit strategy. Fontaine lowboy trailers have a strong reputation in specialized hauling, and the right spec usually comes down to matching the trailer’s deck geometry and axle package to the exact machines being moved.
