Hendrickson’s single-axle Vantraax slider is a tapered-beam, 23,000-pound capacity system designed for flexibility in axle spacing and enhanced load distribution, especially on single-axle trailers.
Users can combine Vantraax single-axle systems for double the adjustability in tandem-axle trailers, allowing axle sets from widespread to closed spaced; or use it as a third axle with a tandem suspension system for increased carrying capacity. However, the HKANT 23K currently is not approved for multi-trailer applications.
The single-axle model trims more than 200 pounds from comparable single-axle sliders on the market, Hendrickson says. Standard with the company’s Advanced Axle/Beam Technology (AXT), the single-axle slider teams tapered beams and a large-diameter axle (LDA) to increase the diameter of traditional axles to 5 3/4 inches, which the company says reduces weight while maintaining component and system strength.
According to Hendrickson, the single-axle Vantraax builds on its K-2 slider box technology and comes standard with high-strength, low-alloy main rails and K-braces for added durability. The tapered-beam design uses the company’s Tri-Functional III Bushing engineered with phosphate-coated inner metal for corrosion protection and a rubber compound for added durability and ride.
The Vantraax single-axle comes standard with Quik-Draw, Hendrickson’s pneumatic, pin-pull mechanism designed for simplified slider repositioning. For applications not requiring a sliding subframe, a “fixed-pin” option allows permanent setting of the rigid structure in a specific location under the trailer, eliminating the need for welding or bolting the box to the trailer frame.
Standard components on the single-axle Vantraax include the company’s Cam Tube System, which reduces S-cam maintenance; Quik-Align for added axle alignment; and an axle-spindle assembly that can help stretch fuel mileage and tire life. Options include the Tiremaax automatic tire inflation system; a selection of wheel ends and disc brakes; and Surelok to help maintain trailer deck height at the loading dock.
