Hendrickson has introduced the Haulmaax EX heavy-duty rubber suspension.
 
Due to advancements in the progressive rate 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, according to the company.
 
Hendrickson notes that as load increases, ride and stability characteristics of the suspension change to meet the application’s needs without an abrupt change in suspension feel. The superior ride translates to reduced road shock and vibration to the vehicle which contributes to longer service life of the cab, chassis and body equipment, the company said
 
To address the growing demand for rubber suspensions across all vocational applications, the Haulmaax EX suspension geometry is optimized to provide better site rating, increased capacity ranges and improved durability, the company said.

“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-lb. site rating for the 46,000-lb. capacity suspension. Haulmaax EX is extremely rugged, supporting the most demanding vocational applications and offering capacities up to 52,000 lbs.,” says Ashley Dudding, director of engineering for Hendrickson Truck Commercial Vehicle System.
