Since its introduction, air suspensions are becoming increasingly used on trucks. Aside from better comfort and improved responsiveness brought forth by the adjustable suspension, the lighter weight of the suspension components are very well-received by truck operators. The lighter the component weight, the more load that the truck can carry. It also lessens the burden on other components like anchor points on the chassis. The lighter weight can also allow the air suspension truck to travel through bridges and other structures with weight limits.
So aside from improving safety, air suspension also helps improve productivity of the operation by allowing trucks to carry more or to complete journeys more quickly by passing through regulated zones or roadways and other weight-limited mode of transportation.
Yet despite the increasing use of air suspensions on trucks, industry experts are still let down by the fact that figures are not meeting expectations. One thing that is stopping air suspension from being used by majority of fleets is the simplicity of repairs and maintenance. As of now, traditional spring suspensions remain the best when it comes to low maintenance costs and minimizing downtimes.
A broken air suspension system is much harder, takes longer, and more expensive to fix compared to coil or leaf springs suspension. While traditional springs may not have the instant adjustability of air suspensions, a fleet with its unique operating conditions can set up the component to best suit the task.
