Primaxx Ex Makes Refinements
For expanded application capabilities, Hendrickson recently launched the PRIMAAX® EXTM Air Suspension system, an enhanced version of the PRIMAAX® heavy-duty, vocational truck air suspension.
PRIMAAX EX improves durability and performance while
delivering a substantial weight savings alternative to competitive systems,
report officials of Hendrickson Truck Systems Group.
Refinements in the PRIMAAX EX system include enhanced joint
integrity and durability, improved handling, increased air spring capacity,
greater disc brake compatibility and improved resistance to torque rod bushing
Launched in 2003, the job-proven PRIMAAX air suspensions
quickly gained the trust of heavy-duty truckers in a variety of vocational and
construction applications including concrete mixers, dump trucks, heavy-haul
tractors, refuse vehicles, truck-mounted cranes and logging trucks.
The PRIMAAX EX system features cast austempered and
shot-peened ductile iron support beams that integrate the attachment points for
greater reliability. Hendrickson manufactures the beams and supplies them as an
engineered sub-assembly to ensure control of product specifications for optimal
performance and durability.
PRIMAAX EX geometry features a new frame hanger and torque
rod configuration. This enhanced geometry provides increased roll stiffness and
reduced roll steer for improved handling. In addition, suspension-induced
driveline vibration is significantly reduced with PRIMAAX EX compared to
competitive trailing-arm air suspensions.
Expanded offerings of the longitudinal torque rods help
provide extended bushing life, ease of serviceability and improved compatibility
to package with disc brakes.
Featuring improvements to the air spring piston shape and
beam interface, the new PRIMAAX EX air springs lift and support the load with
less air pressure. Furthermore, packaging improvements help reduce potential
damage to the air spring.
PRIMAAX EX will be available at most major truck
manufacturers in capacities ranging from 23,000 to 26,000 pounds for
single-axle, 46,000 to 52,000 pounds for tandem-axle and 69,000 to 78,000 pounds
for tridem-axle applications.
PRIMAAX EX features superior ride, handling, stability and
suspension articulation, proving ideal for versatile on- and off-highway
