Fontaine Fifth Wheel announces new top plate for severe-duty applications


Fontaine Fifth Wheel has announced a new top plate designed specifically for severe-duty applications.

The Fontaine H7 features a cast steel housing along with the industry’s only trigger activated self-adjusting locking mechanism in the country, the Fontaine No-Slack locking system.

The H7 and other Fontaine fifth wheels with the No-Slack locking system self-adjust in order to accommodate for wear and for variations in kingpin geometry.

“This means drivers get a snug, secure hassle-free connection as they move from trailer to trailer,” Fontaine reports in its press release.

The design also reduces shock inputs into the frame when braking and accelerating which Fontaine says gives drivers get a smoother ride and components last longer for lower maintenance costs.

“Our mission with the H7 was to simplify our severe duty product line into one cast steel fifth wheel system that uses our most up to date No-Slack locking system,” said Mike Randolph, VP Sales & Marketing North America.

The Fontaine H7 is rated up to 70,000 lbs. vertical load, a drawbar pull rating up to 200,000 lbs. and has the option of being blocked (no-tilt) from the factory. It’s designed for logging, heavy haul, oil field, mining and other severe-duty applications.

“The beauty of the H7 fifth wheel is that it offers a majority of the same working parts that you find in our current No-Slack 6000 and 7000 series top plates so the need to keep additional replacement parts in field will be greatly reduced,” said Paige Petroni, Fontaine’s vice-president of aftermarket.
