“Just like the newly redesigned International HX Series, Hendrickson took a great suspension and made it better,” says Mark Stasell, vice president Vocational Truck Business, Navistar.  “The Haulmaax EX delivers improved performance and durability, which helped our team design the new HX Series for productivity, durability, and comfort.”

With the updated vehicle’s release, Hendrickson says it will be launching its next-generation, heavy-duty rubber suspension Haulmaax EX as the standard rubber suspension offering, addressing the growing demand for rubber suspensions across all vocational applications. The Haulmaax EX suspension is optimized to provide increased site rating, expanded capacity ranges, and improved durability.

Hendrickson says the Haulmaax EX is designed for vocational applications where durability and performance are essential. This innovative suspension offers an ideal balance of unloaded ride quality and loaded stability. Haulmaax EX is the lightest weight suspension in its class, allowing the ability to increase the payload of the vehicle.

These suspensions provide the versatility needed for trucks and tractors that operate both on-and off-highway. The suspension’s equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions. The innovative design eliminates fixed center bushing pivot points to reduce wheel hop, Hendrickson says. When paired with Hendrickson Traax RODs, stability is enhanced, and articulation increased for improved on/off-highway operation, the company adds.

“Customers today expect more out of their vocational suspensions. Haulmaax EX exceeds expectations by expanding on the capabilities of the current Haulmaax design. With up to a 70,000-pound site rating for the 46,000-lb., capacity suspension. Haulmaax EX is extremely rugged, supporting the most demanding vocational applications and offering capacities of 40,000 lb., 46,000 lb., and now 52,000 lb.,” says Ashley Dudding, director, engineering, Hendrickson.

“Hendrickson utilized our industry-leading analysis and validation techniques to ensure Haulmaax EX would meet these rigorous demands, minimize maintenance requirements, and deliver the lightest weight vocational suspension on the market.”
