New Fontaine Double Drop Expandable Trailers For Sale

New Fontaine double drop expandable trailers are built for freight that is too tall, too long, or too specialized for a standard flatbed or fixed lowboy. This trailer class is also called an extendable double drop lowboy or extendable lowbed, and it is designed to carry taller machinery by lowering the cargo deck between the upper deck and rear deck. For buyers comparing listings, the most important starting points are deck length closed versus open, loaded deck height, ground clearance, and rated capacity in a defined span such as 40 tons in 16 feet. Those numbers tell you how the trailer will actually perform with excavators, crushers, pavers, tanks, or other over-dimensional equipment.

Fontaine models in this category are commonly spec'd with a low main deck height around 20 inches, 102-inch overall width, Apitong flooring, steel side rails, multiple pairs of outriggers, and tiedown points such as D-rings spaced for real heavy-haul securement. Extendable deck sections can significantly increase usable well length, which matters when the load cannot be split or repositioned to fit a fixed deck. Buyers should also look closely at kingpin setting, gooseneck design, swing radius, axle spacing, and suspension setting because those details affect tractor compatibility, bridge law planning, turning clearance, and how the trailer scales in the field. Air ride suspension, raise-and-lower control, and flip axle preparation are common specs for operators that need flexibility across different job types and permit conditions.

A Fontaine double drop expandable trailer is usually chosen for the balance it strikes between low loaded height and the ability to stretch for long freight. That makes it a practical option for construction equipment, agricultural machines, transformer components, and industrial pieces that need the well depth of a double drop but also require additional deck length. Many buyers focus on the deck and capacity numbers first, but daily-use features matter too. Outrigger count, traction cleats on the approach, mini boom troughs, lighting layout, and rear deck access all affect loading efficiency and safety. If future axle expansion is part of the plan, prep for a flip axle or third axle is worth verifying up front instead of modifying later.

For heavy-haul fleets, new-spec equipment often means less compromise. Current Fontaine builds are typically configured with modern lighting, durable coatings, and the securement hardware needed for demanding freight. The best fit depends on the freight profile more than the headline model name. A buyer hauling compact but tall machines may prioritize the lowest possible well height and strong ground clearance, while a buyer moving long components may care more about open deck length, crossmember spacing, and extension design. When comparing new double drop expandable trailers for sale, concentrate on how the trailer carries weight in the well, how far it extends, and how easily it integrates with your axle, tractor, and permit strategy.
