Hendrickson's lightweight HAULMAAX® Now Available on International® Trucks
WOODRIDGE, Ill. — Hendrickson officials announced availability of HAULMAAX®, a lightweight, heavy-duty rear suspension, on International® Truck and Engine Corporation 5000i and 7000 series vocational trucks.

Steadily increasing market acceptance for HAULMAAX prompted International to offer this advanced suspension system. With more than 90 years of experience in the commercial vehicle industry, Hendrickson continues to exceed industry demands by offering the lightweight, cutting-edge HAULMAAX heavy-duty truck suspension for vocational truck and tractor applications.

The HAULMAAX suspension represents a state-of-the-art, walking-beam suspension that allows truck owners and operators to carry hundreds of pounds of additional payload on each run while maximizing durability with high-strength materials and advanced manufacturing methods.

“HAULMAAX utilizes an innovative spring geometry that couples natural rubber with a high-density thermo set material for the preferred ride and handling characteristics desired in construction, refuse, logging and other heavy-duty applications,” reports Gerry Remus, vocational marketing manager for Hendrickson Truck Suspension Systems. “This premium suspension system adjusts to the load, providing excellent ride quality and loaded stability for driver comfort and confidence on the job site.”

Unique to HAULMAAX, this new variable rate spring system helps cushion more than just the driver. It also helps protect the cab, chassis and body equipment from vibration and harshness, which can extend equipment life while reducing maintenance costs.

“Lightweight design and superior ride characteristics are certainly key features of the HAULMAAX system and provide customer value when used on International trucks, but also key is the maintenance savings that can be realized,” reports Steve Andrews, general manager of Hendrickson Truck Suspension Systems.

By eliminating the center bushings and providing easy access to all components, HAULMAAX helps reduce maintenance costs for truck owners. The unique spring system helps promote long service life and easy accessibility, while the industry-proven and rugged bar pin axle connection extends bushing life and provides alignment capability for better tire wear.

Hendrickson helps reduce maintenance costs for truck owners, allowing the vehicle to remain on the road longer, hauling payload and generating revenue.

Shock absorbers are available to provide enhanced ride improvement in many applications; outboard mounting improves serviceability. Hendrickson ULTRA ROD™ torque rods come standard on HAULMAAX. These torque rods result in longer bushing life and additional weight savings.

Proven with extensive laboratory fatigue and vehicle durability testing, HAULMAAX is designed, tested and approved specifically for the demanding requirements unique to vocational truck and tractor applications. Through cooperative development, Hendrickson and International optimized the design of the suspension and associated cross members.

For demanding off-road and job-site conditions, HAULMAAX offers up to 17 inches of loaded, diagonal wheel articulation to maintain traction with all drive wheels.

“HAULMAAX demonstrates our continued leadership in heavy-duty suspension technology by delivering innovative ride solutions that improve traction, reduce maintenance costs and, most importantly, can improve profits for our customers,” added Remus. “The weight savings with a HAULMAAX suspension can result in over 500 pounds of additional payload in comparison to competitive steel spring suspensions.”
