Hendrickson Truck Commercial Vehicle Systems announced the new Progressive Load Spring (PLS) for its HAULMAAX vocational rear suspension system. The PLS is an elastomeric spring which works in concert with the bolster springs in Hendrickson’s patented Vari-Rate Spring system providing unparalleled ride quality in both the loaded and unloaded conditions.
The new Progressive Load Spring will improve the already rugged and reliable HAULMAAX rear suspension system by providing key advancements in ride quality and stability. The PLS is continuously engaged, thus providing excellent unloaded ride performance.
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.
