CANTON, Ohio — Hendrickson’s new, lighter weight INTRAAX AANL 23K low-ride / liftable integrated trailer suspension system began rolling off assembly lines this month.
With a weight savings of 75 pounds, INTRAAX AANL 23K replaces the AAL 23K as Hendrickson Trailer Suspension System’s lightest 23,000-pound capacity low-ride / liftable suspension system. INTRAAX AANL uses Hendrickson’s Advanced Axle / Beam Technology (AXT), which teams tapered-beam and Hendrickson Large-Diameter Axle (LDA) technologies, to enhance component system strength, while reducing weight.
The AANL tapered-beam design uses TRI-FUNCTIONAL III bushings which have a rubber compound for durability and ride.
LDA increases the diameter of today’s traditional five-inch axle to five and three-quarters inches while slightly reducing the wall thickness. The wall thickness reduction combined with the increased diameter creates a more efficient use of material, which enhances strength while reducing weight, the company claims, adding that LDA delivers as much as a 15-percent increase in bending and torsional stiffness compared to the five-inch (0.460-inch) walled axle, which reduces axle deflection under, load helping keep the axle straighter.
“With this suspension, there should be no perception that lighter weight somehow equates to a reduction in strength or durability,” says Keith McComsey, vocational program manager for Hendrickson Trailer Suspension Systems.
It is offered in ride heights from 6.5 to 17 inches.
