Areas of Application: Trailers and Semitrailers

Trailers and semitrailers are increasingly fitted with air springs to ease the transportation of fragile goods and to protect the vehicle body. Usually, each axle assembly has two air springs behind the axle. Air-spring axles are built as steered single axles and as single, double and triple axle assemblies.

For multi-axle combinations, one axle is frequently provided with an axle-lifting device to protect the tyres on empty runs. Air springs for this application are characterised by a high load carrying capacity and large spring deflections.
