Hendrickson Truck Commercial Vehicle Systems has partnered with Navistar to offer Haulmaax EX as a part of the chassis enhancements of the International HX.
With the updated vehicle’s release, Hendrickson will be launching its next-generation, heavy-duty rubber suspension Haulmaax EX as the standard rubber suspension offering. The company says the Haulmaax EX suspension is optimized to provide increased site rating, expanded capacity ranges and improved durability.
Haulmaax EX offers an ideal balance of unloaded ride quality and loaded stability, Hendrickson says, adding it 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 company says. The suspension’s equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions. The 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-lb. 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 lbs., 46,000 lbs., and now 52,000 lbs.,” says Ashley Dudding, director of engineering for Hendrickson.
