Fontaine Lowboy Trailers For Sale in Pennsylvania

Fontaine lowboy trailers are built for hauling tall, heavy equipment that will not sit legally or safely on a standard flatbed. In Pennsylvania, that usually means construction iron, paving machines, dozers, excavators, loaders, and other equipment where loaded deck height matters as much as payload. Fontaine is well known in the detachable gooseneck market, and many buyers focus first on deck height, concentrated load rating, and how the trailer is configured for future axle additions. A model in the 55-ton class, for example, may be rated in a defined deck length such as 13 feet, which is the number that matters when you are carrying a machine with heavy axle weights or point loads rather than a uniform load spread.

One of the key buying decisions is gooseneck style and deck layout. Hydraulic detachable gooseneck lowboys make loading easier for tracked and wheeled equipment, especially when frequent loading cycles are part of the job. Non-ground-bearing neck designs are common on premium heavy haul trailers because they simplify hook-up and detachment in more varied site conditions. Buyers should also look closely at kingpin settings, loaded fifth wheel height, swing radius, and main deck dimensions. On Fontaine units, it is common to see 102-inch overall width, low deck heights around 18 inches, and main deck lengths in the mid-20-foot range. Those numbers directly affect loading angle, bridge compliance strategy, and the types of machines the trailer can handle without reconfiguration.

Suspension and axle setup matter just as much as the headline ton rating. Air ride suspensions, lift axles, dump valves, and mechanical ride height controls all play into load equalization, deck approach, and everyday usability. Many Fontaine lowboys are set up with tri-axle groups and are prepped for rear flip axles or other modular axle connections, which gives an operator room to adapt to changing permit work. That flexibility is important in heavy haul, where one trailer may spend one week moving a 35-ton excavator and the next week carrying a heavier machine that requires additional axle capacity. Tire size, suspension spacing, and flip axle compatibility are not minor details. They affect permit routing, overall bridge formula, and how easily the trailer can be matched to the work.

The smaller details are often what separate a basic lowboy from one that works hard every day. Outriggers, D-rings, chain slots, hammer plates, recessed crossmembers, tool storage, flag holders, strobes, and side lighting all contribute to safer loading and better cargo securement. Wood side-rail flooring, removable swing outriggers, and multiple tie-down points are especially useful when hauling mixed equipment or attachments. Fontaine lowboy trailers are often chosen by contractors and specialized carriers that need a durable deck, predictable loading geometry, and a trailer platform that can be built out with rear flip or modular components over time. If the work involves concentrated machine weights, frequent loading, and permit-sensitive dimensions, a properly spec'd Fontaine lowboy is a serious heavy haul tool.
