Q. How do air suspension work and what are the main benefits for using air suspensions?

A. An air suspension provides improved ride quality by isolating the truck and trailer from road inputs. The air inside the suspension air springs compresses or expands as the suspension moves up and down, allowing suspension movement that is independent of vehicle movement. Isolating the vehicle by using air springs protects the structure and cargo from road inputs that can cause damage. It also provides a more comfortable experience for the driver.

Air suspensions provide improved cargo protection, which can help reduce claims for damaged freight. This can also expand the types of cargo that can be transported. An air suspension will provide a smoother ride especially when the vehicle is bobtail or empty. In an air suspension the height of the chassis is maintained at a constant level irrespective of the load – so this allows benefits when the vehicle is at a loading dock. Air suspensions also help protect components like lights and hinges, which can help reduce vehicle maintenance costs.

Air suspensions automatically equalize the loading between the trailer axles making it easier for the operator to correctly position trailer loads and avoid axle overload fines. Axles may also be lifted when not needed, which can reduce tire and brake wear, increase fuel mileage, and reduce road toll costs. Hendrickson air suspensions provide excellent roll stability and are one of the lightest weight suspension options, which allows operators to increase fuel mileage and cargo capacity.
