Fontaine’s New H7 Top Plate Designed for Severe Duty

Fontaine Fifth Wheel designed a new top plate, the Fontaine H7, specifically for severe-duty applications.

The H7 replaces the H5092 and X5092 Series and combines them into one fifth-wheel system. Like the 7000 Series, the H7 features a cast-steel housing and the Fontaine No-Slack locking system, the only trigger activated self-adjusting locking mechanism in the industry.

“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, vice president of sales and marketing in North America.

Fontaine’s exclusive fifth-wheel lock self-adjusts in order to accommodate for wear and variations in kingpin geometry, so drivers get a snug, secure, hassle-free connection as they move from trailer to trailer. The design also reduces shock inputs into the frame when braking and accelerating, so drivers get a smoother ride and components last longer for lower maintenance costs.

The H7 is rated up to 70,000 pounds for a vertical load, with a drawbar pull rating up to 200,000 lbs, and has the option of being blocked (no-tilt) from the factory, making it ideal 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, VP of aftermarket.
