Fifth-Wheel Plate Mount

Posted: January 21, 2015

Recognizing that even a small amount of excess weight can make a big difference when it comes to truck efficiency, Fontaine Fifth Wheel says it’s replacing two of its adjustable plate-mount fifth-wheel brackets with a single lightweight model. The new PML adjustable mount is an average of 10 lb lighter than the company’s PMA and APB models, but it delivers the same load capacity.

The new PML bracket offers all the features of the PMA and APB brackets, but with a new reinforced cast-steel design that cuts weight. Drivers will not notice any difference in capability but at the end of the month fuel usage will be measurably lower, says Fontaine.

The new 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 fifth-wheel assembly to be moved forward or backward in two-inch increments to help balance any load. Since there is no sliding mechanism, the fifth wheel 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 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 lb.
