SUSPENSION SYSTEMS VOCATIONAL / HEAVY-HAUL
PRIMAAX ® EX Severe-duty vocational air suspension • Engineered specifically for severe-duty operations for up to 100 percent off-highway use • Axle connection and torque rods help reduce torsional axle stress and driveline vibration • Large-volume, low-frequency air springs provide a smooth ride for on- and off-highway use • Up to12.5 in. of diagonal wheel articulation for superior mobility • Recommended applications: oil field, heavy haul, logging, defense, mixer, crane mounted, dump, refuse and tractor • Capacities of 23,000 and 26,000 lbs. (single axle), 46,000 and 52,000 lbs. (tandem axle) and 69,000 and 78,000 lbs. (tridem axle) HAULMAAX ® Heavy-duty lightweight rubber suspension • Provides superior combination of empty ride and loaded stability • Reduced maintenance with fewer bushings and no lubrication requirements • Up to 17 in. of diagonal articulation for greater worksite mobility • Recommended applications: dump, refuse, mixer, logging and defense • Capacities of 40,000 and 46,000 lbs.
HAULMAAX ® EX Next generation heavy-duty lightweight rubber suspension • Hundreds of pounds lighter than competitive suspensions • Increased job site rating for expanded applications • Superior combination of empty ride and loaded stability • Improved durability through advanced elastomer technology • Reduced maintenance due to optimized geometry and lubrication-free components • Up to 17 in. of diagonal articulation for greater mobility
• Recommended applications: dump, refuse, mixer, logging, crane / boom and defense • Capacities of 40,000, 46,000 and 52,000 lbs.
ULTIMAAX ® Advanced severe-duty rubber suspension
• Optimized design to balance robust durability and weight savings • Progressive load springs provide a unique balance of unloaded ride quality and loaded stability • Fabricated walking beam design equalizes axle loading while providing optimal clearance, axle travel and weight • Recommended applications: dump, logging, mixer, refuse, crane / boom, platform, oil field and mining
