Haulmaax EX works to provide the versatility needed for trucks and tractors that operate both on- and off-highway.

Hendrickson Truck Commercial Vehicle Systems has partnered with Autocar to offer the next-generation Haulmaax EX as a part of the chassis enhancements for ACX and DC-64 models.

Haulmaax EX works to 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.

“Customers today expect more out of their vocational suspensions. Haulmaax EX exceeds expectations by expanding on the capabilities of the current Haulmaax design,” said Ashley Dudding, director of engineering for Hendrickson. “With up to a 70,000-lb. site rating for the 46,000-lb. capacity suspension.”

According to Hendrickson, the design eliminates fixed center bushing pivot points to reduce wheel hop. When paired with Hendrickson TRAAX RODs, stability is enhanced, and articulation increased for improved on/off-highway operation.

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