Hendrickson announced the HAULMAAX EX, a heavy duty rubber suspension. Launched in 2004, HAULMAAX has earned the reputation for being a standard in lightweight and durable rubber suspensions in the vocational industry. The progressive load spring system has benefited users with a combination of excellent ride quality and loaded stability.
Due to advancements in the progressive load spring technology, HAULMAAX EX was designed with more vertically angled bolster springs carrying the majority of the payload in compression during the empty or lightly loaded condition, resulting in excellent ride quality.
As the load increases, ride and stability characteristics of the suspension change to meet the application’s needs without an abrupt change in suspension feel. The ride translates to reduced road shock and vibration to the vehicle which contributes to longer service life of the cab, chassis, and body equipment and less driver fatigue, says the company.
The HAULMAAX EX suspension geometry is optimized to provide increased site rating, increased capacity ranges, and improved durability. “Customers today expect more out of their vocational suspensions and HAULMAAX EX exceeds those expectations by expanding on the capabilities of the current HAULMAAX design with up to a 70,000 pounds site rating for the 46,000-pound capacity suspension. HAULMAAX EX is extremely rugged, supporting the most demanding vocational applications and offering capacities up to 52,000 pounds,” says Ashley Dudding, director of engineering for Hendrickson Truck Commercial Vehicle System.
“Hendrickson utilized our industry leading analysis and validation techniques to assure HAULMAAX EX meets these rigorous demands, is maintenance free, and is the lightest weight vocational suspension in the market,” added Dudding.
HAULMAAX EX is available in capacities of 40,000, 46,000, and 52,000 pounds.
