Hendrickson partnered with Mack Trucks to offer customers the Next Generation HAULMAAX EX, a heavy-duty rubber suspension system. The HAULMAAX EX suspension’s equalizing beam distributes the load equally between both axles in off-road and uneven terrain conditions and provides 17 inches of diagonal articulation, the company says. The system was designed to eliminate fixed center bushing points, reducing wheel hopping. With an integrate jounce stop, HAULMAAX EX protects from overloads, maximizing life for the progressive load springs and bolster springs. “HAULMAAX EX is extremely rugged, supporting demanding vocational applications and offering capacities of 40,000 pounds, 46,000 pounds and now 52,000 pounds, with up to 75,000-pound site rating,” said Ashley Dudding, director of engineering for Hendrickson, in a statement. “Hendrickson utilized our industry-leading analysis and validation techniques to ensure HAULMAAX EX would meet rigorous job-related demands, minimize maintenance requirements and deliver an advance, lightweight vocational suspension to the market.” Authorized Mack dealers now are selling the Mack TerraPro and LR cab-over vehicles with the HAULMAAX EX suspension. An increased tire clearance on the HAULMAAX EX suspension, which meets SAE standard for tire chain clearance, includes packages with 315 tires and 9-inch steel wheels.
