Hendrickson launches HAULMAAX EX system for Freightliner

Hendrickson has partnered with Freightliner to offer its HAULMAAX EX heavy-duty rear rubber suspension system as a part of the chassis enhancements for all Freightliner Vocational M2, SD and Plus models.

“HAULMAAX EX exceeds expectations by expanding on the capabilities of the original HAULMAAX design, with up to a 70,000-lb. job site rating for the 46,000-lb. capacity suspension,” said Ashley Dudding, director of engineering at Hendrickson. “HAULMAAX EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 lbs., 46,000 lbs., and now 52,000 lbs.”

The company said HAULMAAX EX suspensions provide the versatility needed for trucks that operate both on-and off-highway. Equalizing beams on the suspension distribute the load equally between both axles to maintain traction in off-road and uneven terrain conditions. An integrated jounce stop protects the spring system from overcompressing,which Hendrickson claims helps to extend component life and reduce maintenance costs.  When paired with Hendrickson TRAAX ROD torque rods, stability is enhanced and articulation is increased for improved on/off-highway operation. 

 “Hendrickson utilized our industry-leading analysis and validation techniques to ensure HAULMAAX EX would meet these rigorous demands, minimize maintenance requirements and deliver an advanced, lightweight vocational suspension to the market,” Dudding concluded.
