Hendrickson introduces industry's first "shockless" air suspension

Hendrickson Trailer Commercial Vehicle Systems takes low maintenance suspension systems to the next level with the launch of its latest innovation, Zero-Maintenance Damping (ZMD) ride technology, available exclusively through Hendrickson beginning Q1 2013.

"Our new Zero-Maintenance Damping air springs take the hassles of a common suspension wear item – the shock absorber – out of the maintenance equation entirely," remarks Scott Fulton, director of new product development at Hendrickson Trailer Commercial Vehicle Systems. "We are excited and proud to unveil this one-of-a-kind technology that makes 'shockless' air suspension systems a reality."

Available on select VANTRAAX integrated air slider models, ZMD technology provides reduced maintenance by eliminating the shock absorbers. Robust chain down-stops replace the rebound limiter function traditionally performed by the shock absorber.

In addition to reducing the risks associated with roadside inspections and CSA violations, these heavy-duty down-stops provide maximum durability, which translates to maintenance savings over the life of the trailer. Moreover, the robust down-stops provide reliable protection for trailers being loaded onto rail freight cars.

An additional benefit of Zero-Maintenance Damping air springs is enhanced ride quality. ZMD air springs integrate the damping function traditionally performed by the shock within the air spring itself by exchanging pressurized air through channels interconnecting the bellows and piston of this patent-pending air spring. Unlike a shock absorber, whose damping capacity is finite and deteriorates with age, ZMD air springs provide continuous damping at a consistent rate over the life of the air spring, increasing trailer component life.

Hendrickson's state-of-the-art research and development testing, combined with real-world road conditions, has shown that ZMD achieves superior suspension damping, which translates to unmatched ride quality, driver comfort and cargo protection.
