Recognizing that even a small amount of excess weight can make a big difference when it comes to truck efficiency, Fontaine Fifth Wheel is replacing two of its adjustable plate mount fifthwheel brackets with a single lightweight model. The new PML Adjustable Plate Mount is an average of 10 lbs lighter than Fontaine’s PMA and APB models, but it delivers the same load capacity.
The PML Adjustable Plate Mount is composed of fixed brackets that sit on a steel plate base. Each side of the base has six mounting holes. The multiple mounting holes allow the fifthwheel assembly to be moved forward or backward in two-inch increments to help balance any load. Since there is no sliding mechanism, the fifthwheel assembly is lighter, and there are fewer moving parts to maintain.
To further minimize maintenance needs, the PML mount’s brackets feature greaseless liners. The liners ensure there is no metal-on-metal contact between the top plate and the bracket, which reduces wear and extends the life of the fifthwheel assembly. Dual durometer bushings aid in shock absorption to provide a smooth ride.
The PML mount is compatible with Fontaine’s No-Slack II 6000, 7000, and 7000CC top plates for standard- to moderate-duty on-highway use. When paired with a 6000 top plate, the PML assembly has a 50,000-lb vertical load capacity. A PML assembly equipped with a 7000 or 7000CC top plate can handle a vertical load of up to 55,000 lbs.
