New Fontaine Lowboy Trailers For Sale in Pennsylvania

New Fontaine lowboy trailers are built for concentrated heavy equipment loads, low deck height, and the kind of daily abuse that comes with construction, paving, utility, and specialized transport work. Fontaine is one of the better-known names in detachable gooseneck trailer design, and buyers usually come to this category looking for a balance of rated capacity, deck length, loaded deck height, and expandability. In Pennsylvania, that matters because route conditions can change quickly from interstate running to narrow jobsite access, steep approaches, and uneven ground. A lowboy, also known as a low-bed or detachable gooseneck trailer, is the standard choice when load height is critical and standard deck trailers will not keep you legal or practical.

The first buying decision is usually trailer style and rating. Many Fontaine lowboys in this class fall into the 55-ton range, with common configurations built around a hydraulic detachable gooseneck, a low boom well, and a three-axle air ride bogie. Main deck heights commonly run in the high teens to low 20-inch range, which is a major advantage when hauling excavators, dozers, crushers, or other tall iron. Deck construction often includes Apitong or nominal wood flooring, removable swing outriggers, multiple pairs of D-rings, chain slots, and recessed crossmember layouts designed to support securement flexibility. If your freight changes from one week to the next, details like clear deck length, top deck length, and outrigger count matter just as much as the ton rating on paper.

Fontaine buyers also pay close attention to detach style, ride height settings, and axle add-on compatibility. Hydraulic non-ground-bearing goosenecks are common because they speed up loading and unloading while keeping the trailer versatile across different tractors and job conditions. Features like adjustable loaded fifth wheel height, removable kingpin settings, manual dump valves, ride height control valves, air lift axles, and chain-lift front axles all affect how the trailer loads, tracks, and transfers weight. Some models are fixed, while others are modular and designed to accept neck extensions, rear spreaders, or flip axles. That matters if you expect to move from a 55-ton machine load today to a longer or heavier permitted load later. A buyer comparing Fontaine lowboys should confirm not only base capacity, but also deck rating by length, swing radius, flip axle compatibility, and suspension setting.

Pennsylvania heavy haul operators should also consider practical compliance and maintenance points before choosing a new Fontaine lowboy trailer. Tire size, wheel material, suspension brand, lighting package, amber strobes, flag holder placement, and covered tool storage all affect day-to-day usability. A trailer with a lower deck and stronger securement package may save time on permits and loading, but only if the deck length and approach angle fit your equipment. If you haul pavers, rollers, or mixed fleet equipment, wood-filled ramps, hammer plates, wheel covers, and full-width loading areas can make a big difference. The best Fontaine lowboy for your operation is usually the one that matches your common load profile first, then gives you enough adaptability for permit work, flip axle additions, and changing axle weight requirements without overbuying trailer weight.
