The Ultimaax severe-duty rubber suspension for vocational markets, available initially in capacities of 46,000, 52,000 and 60,000 lbs., has been introduced by Hendrickson Truck Commercial Vehicle Systems. Ultimaax, according to the company, delivers enhanced stability, handling and ride quality where vehicles encounter unexpected ground conditions by integrating Hendrickson walking (equalizing) beam technology with a progressive rate spring.
The Ultimaax system, the manufacturer notes, has been through more extreme testing than any product developed by Hendrickson, including component and proving ground validations. In addition, fleets have been running prototype units in extreme applications in North America for the last five years.
