Abstract

See full text

A system for providing suspension to a cab of an excavation machine such as a trencher or a surface mining machine. The system includes air cushions and elastomeric dampeners positioned between a platform and the cab. The air cushions allow for a larger displacement than the elastomeric dampeners. The air cushions have a lower natural frequency than the elastomeric dampeners. The elastomeric dampeners stabilize and support the cab in various degrees of freedom that are not supported by the air cushions.
