Hendrickson Launches Revolutionary VANTRAAX® ULTRAA-K™ Air Slider System

CANTON, Ohio — Hendrickson Trailer Commercial Vehicle Systems announces the launch of VANTRAAX® ULTRAA-K™, the industry’s strongest and lightest slider system, available beginning July 2014.

“The ULTRAA-K truly represents game-changing technology that redefines the standard for ride quality low-cost operations for trailers,” remarks Perry Bahr, vice president and general manager of Hendrickson Trailer Commercial Vehicle Systems. “Building on the engineering expertise and success of VANTRAAX, the industry’s first integrated air slider system, Hendrickson is excited to unveil the next level of air slider technology with the ULTRAA-K model,” adds Bahr.

Hendrickson has infused thoughtful, innovative designs into every aspect of the ULTRAA-K system. From the slider box to Zero Maintenance Damping™ to pivoting mud flap brackets, ULTRAA-K is a high-performance system that allows fleets to experience superior ride quality while carrying more cargo per load and keeping trailers on the road and out of maintenance bays.

A powerful combination of lightweight durability, the ULTRAA-K is stronger than VANTRAAX-HD models and lighter than any other slider system in the industry by nearly 100 pounds. The high-tech, hot-dip coating process allows Hendrickson to back ULTRAA-K with a 10-year structural corrosion warranty, unmatched in today’s marketplace.

Exclusive, patent-pending features further elevate the ULTRAA-K’S elite status among air slider systems. Instead of shock absorbers, ULTRAA-K uses Zero Maintenance Damping™ (ZMD™) air springs for suspension damping. With no moving parts, these unique air springs are designed to provide uniform and consistent damping levels over their lifespan.

Since the air spring’s damping capacity does not degrade or diminish over time like a shock absorber, ZMD air springs outperform shocks in the areas of ride quality, cargo protection, downtime and maintenance costs. ZMD reduces the risks associated with roadside tickets and CSA violations associated with leaky or misting shocks. Additionally, the robust, covered chain down-stops protect the suspension and trailer when lifting the unit for rail transfer.

Innovative features like pivoting mud flap brackets are standard on ULTRAA-K and offer additional value to fleets seeking reliability and less maintenance. This unique feature is only available on ULTRAA-K and can drastically reduce costs associated with damaged mud flaps and mud flap mounting angles.
