For haulers running heavy-duty, over-the-road box, and refrigerated vans, Hendrickson unveils a 46,000-lb-capacity Vantraax slider system in a weight-saving 121-inch configuration.
The 121-inch Vantraax HKANT 46K system uses Hendrickson's Advanced Axle/ Beam Technology (AXT) to trim more than 300 pounds compared with similar-capacity wide-spread sliders.
AXT combines tapered-beam and large-diameter axle (LDA) technologies for increased strength and reduced weight. LDA increases the diameter of traditional five-inch axle by about three-quarters of an inch.
LDA also delivers as much as a 22% increase in bending and torsional stiffness versus the five-inch axle tube. This reduces tube deflection under loads to keep the axle straighter and help enhance fuel efficiency and tire wear.
The HKANT 46K builds on Hendrickson's patented K-2 slider box technology and comes standard with high-strength, low-alloy main rails and K-braces. Robust main rails also increase resistance to single-wheel impacts.
The tapered-beam design uses the Tri-Functional III bushing to deliver the same smooth ride as the closed-space HKANT 46K. Patented Tri-Functional III bushings feature phosphate coated inner metal for corrosion protection and a rubber compound for outstanding durability and ride.
Standard with Quik-Draw, Hendrickson's fully pneumatic pin-pull mechanism, the 121-inch spread Vantraax can also be ordered with a “slider-pins-only” option for use in a fixed application.
The HKANT 46K wide-spread model has D-shaped holes in the slider main rails and new D-shaped slider pins. This hole shape reduces potential distortion during forming and permits easier repositioning of the slider box. The durable zinc-plated slider pins resist wear and grooving.
