Hendrickson's Haulmaax EX now available for Freightliner vocational tractors

Hendrickson's Haulmaax EX suspension

Hendrickson Truck Commercial Vehicle Systems announced Tuesday it has partnered with Freightliner Trucks to offer Haulmaax EX, Hendrickson’s Next Generation heavy-duty rear rubber suspension system as a part of the chassis enhancements for all Freightliner Vocational M2, SD and Plus models.

Hendrickson says the Haulmaax EX suspension provides 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 over compressing, helping 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, the company says.

“Customers today expect more out of their vocational suspensions. 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. Haulmaax EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 lb., 46,000 lb., and now 52,000 lb.,” says Ashley Dudding, director of Engineering at Hendrickson.

“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.”
