For haulers running heavy-duty, over-the-road box and refrigerated vans, Hendrickson has designed a 46,000-pound-capacity Vantraax slider system in a weight-saving 121-inch configuration.
Hendrickson says the 121-inch Vantraax HKANT 46K system uses the company’s Advanced Axle/Beam Technology (AXT) to trim more than 300 pounds compared to similar-capacity wide-spread sliders.
Hendrickson says AXT combines tapered-beam and large-diameter axle (LDA) technologies for increased strength and reduced weight, while LDA increases the diameter of today’s traditional five-inch axle by about three-quarters of an inch, which reduces weight while improving component and system strength.
LDA also is designed to deliver as much as a 22-percent increase in bending and torsional stiffness compared to the five-inch axle tube, which Hendrickson says reduces tube deflection under loads to keep the axle straighter and help enhance fuel efficiency and tire wear.
The 121-inch spread HKANT 46K builds on Hendrickson’s patented K-2 slider box technology, plus comes standard with high-strength, low-alloy main rails and K-braces engineered for added durability and strength. The robust main rails also increase resistance to single-wheel impacts, according to the company.
The tapered-beam design uses the high-performance Tri-Functional III bushing designed to deliver the same smooth ride as the closed-space HKANT 46K. Tri-Functional III bushings feature phosphate-coated inner metal for corrosion protection and a rubber compound engineered to promote for outstanding durability and ride.
Standard with Quik-Draw, Hendrickson’s fully pneumatic pin-pull mechanism, the 121-inch spread Vantraax also can be ordered with a “slider-pins-only” option for use in a fixed application.
