ABSTRACT:
A shipping container including a cover and a base wherein the base includes support platform that is supported on its corners by four pneumatic springs. The pneumatic springs are mounted at an angle to provide three-dimensional shock and vibration isolation of the platform. The platform is tuned and is selected to have a predetermined weight to provide vibration isolation for shipped objects having a weight range of from about zero to a predetermined maximum weight. An air accumulator and manifold are employed in cooperation with the pneumatic springs to provide the desired pneumatic spring characteristic such as reduced stiffness and reduced natural frequency.
