Heavy-duty: 2023 HDAW event theme is ‘Shift. Adapt. Grow.’
Hendrickson Truck Commercial Vehicle Systems has partnered with Mack Trucks to offer the Next Generation HAULMAAX EX heavy-duty rubber suspension. The Mack TerraPro and LR cab-over vehicles are now available for purchase with the HAULMAAX EX suspension at authorized Mack dealers.
The HAULMAAX EX suspension’s equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions and provides 17 in. of diagonal articulation, Hendrickson noted in a press release. The design eliminates fixed center bushing pivot points to reduce wheel hop. An integrated jounce stop provides overload protection to maximize the life of the progressive load springs and bolster springs. The tire clearance was increased on HAULMAAX EX to include packages with 315 tires and 9-in. steel wheels while continuing to meet the SAE standard for tire chain clearance.
