Hendrickson PLS available for vocational trucks


Hendrickson Truck Commercial Vehicle Systems introduced Tuesday its new Progressive Load Spring (PLS) for HaulMaax vocational rear suspension system. The PLS is an elastomeric spring which works in concert with the bolster springs in Hendrickson’s Vari-Rate Spring system.

The company says its 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.

“PLS is another example of how our customers drive innovation at Hendrickson,” says David McCleave, director of marketing for Hendrickson Truck Commercial Vehicle Systems. “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.”
