Fontaine Heavy-Haul, a lowbed and extendable trailer company, is introducing 53 foot Xcalibur extendable trailers that are California legal. The four different models offer a choice of spring or air suspension with tandem or tridem axles.
The four new Xcalibur extendable models are 53 feet in the closed position and 90 feet fully opened. When the trailers are closed and the sliding axles are in their most forward position, the distance between the kingpin and the rear axle center is less than 40 feet, making these trailers legal to operate in the state of California.
A cable management system helps protect telescoping air and electrical lines from damage. Sliding axles are attached to the trailer in a “Slider Box” so they move together as a unit. For greater strength and durability, steel I-Beam crossmembers are welded on 12 inch centers. Steel reinforced mainbeams, structural steel siderails, and steel front and rear skirts complete the heavy-duty design.
