Used Fontaine Lowboy Trailers For Sale in Pennsylvania

Used Fontaine lowboy trailers are a common choice for heavy equipment hauling, construction fleets, paving contractors, and specialized carriers that need low deck height and dependable load distribution. Also called lowbed trailers or detachable gooseneck trailers depending on configuration, these trailers are built to move tall and heavy machines that would be difficult to load or legal to haul on a standard flatbed. Fontaine is well known in the lowboy segment for hydraulic detachable gooseneck designs, strong perimeter frames, and configurations that can be adapted with flip axles, spreader setups, and neck extensions to match changing weight and bridge requirements.

The first decision most buyers make is capacity and deck layout. In this category, 40-ton and 55-ton class trailers are common, with main deck heights often in the mid-teens to around 20 inches depending on model and suspension setup. Buyers should compare loaded deck height, main deck length, rear deck length, and whether the trailer is fixed, extendable, or modular. A lower loaded deck can be a major advantage for moving excavators, dozers, pavers, crushers, and other high-profile equipment through Pennsylvania routes with tight overhead clearances. Extendable and modular Fontaine lowboys add flexibility for longer machines or specialized loads, while fixed well trailers are often simpler and lighter for routine hauling.

Gooseneck design and axle configuration matter just as much as published tonnage. Many Fontaine lowboys use hydraulic detachable, non-ground bearing necks, which speed loading and unloading for tracked equipment and reduce the need for ramps. Ride height positions, kingpin settings, suspension setting, lift axle function, and flip axle compatibility all affect how the trailer works with your tractor and how easily you can tailor axle spacing to the job. Air ride suspensions from brands such as Hendrickson or Ridewell are common, along with manual dump valves, mechanical ride height controls, and 275/70R22.5 rubber on aluminum-steel wheel packages. Buyers should also look closely at practical equipment such as swing-out outriggers, D-ring count, hammer plates, load-bearing wheel covers, tool trays, and wood or Apitong decking, since these details directly affect securement, durability, and day-to-day productivity.

For used buyers in Pennsylvania, condition matters beyond the frame and deck. Check brake wear, tire match, neck and 5th wheel condition, crossmember spacing, deck repairs, and signs of concentrated loading over recessed areas. Heavy haul permits, bridge laws, and regional road conditions make axle spacing and attachment options especially important in this market. A well-matched used Fontaine lowboy can handle everything from local contractor moves to multi-state specialized hauling, but the right trailer is the one whose deck geometry, detachable neck style, axle package, and legal payload profile fit the loads you actually run.
