Hendrickson improves ride quality with new spring design

Hendrickson Truck Commercial Vehicle Systems has incorporated a “progressive load spring” (PLS) into its Haulmaax vocational rear suspension system for a smoother ride. According to the company, the “PLS is an elastomeric spring which works in concert with the bolster springs in Hendrickson’s patented Vari-Rate spring system to provide unparalleled ride quality in both the loaded and unloaded conditions.”

The PLS is continuously engaged, thus providing excellent unloaded ride performance, Hendrickson said. As payload increases, the spring further engages and functions together with the rubber bolster springs to provide additional stability. The PLS’s constant engagement also eliminates the need for shim adjustments for most applications, resulting in reduced maintenance and lowered cost.

“PLS is another example of how our customers drive innovation at Hendrickson. By listening to our customers and monitoring the trucking industry, we are able to continuously improve our products, and we are never complacent with our technology,” said David McCleave, director of marketing for Hendrickson Truck Commercial Vehicle Systems.
