Freightliner now offering Hendrickson Haulmaax suspension

Woodridge, Illinois-based Hendrickson Truck Commercial Vehicle Systems has partnered with Freightliner Trucks to offer the Haulmaax EX suspension system. Hendrickson calls Haulmaax EX its next generation heavy-duty rear rubber suspension system.

According to Hendrickson, Haulmaax EX is now among chassis enhancements for all Freightliner vocational M2, SD and Plus model trucks.

“Customers today expect more out of their vocational suspensions,” says Ashley Dudding, director of engineering at Hendrickson. “Haulmaax EX exceeds expectations by expanding on the capabilities of the original Haulmaax design, with up to a 70,000-pound jobsite rating for the 46,000-pound capacity suspension.

“Haulmaax EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 pounds, 46,000 pounds, and now 52,000 pounds. 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.”

Hendrickson says its Haulmaax EX suspension provides versatility needed for trucks that operate both on- and off-highway. Equalizing beams on the suspension have been designed to distribute the load equally between both axles to maintain traction in off-road and uneven terrain conditions.

According to Hendrickson, 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 states.
