Reciprocating machinery creates large vibration forces which frequently require isolation from the surrounding building structure. Large forces or doubtful machine stability may require the use of an inertia block of steel or concrete to provide low dynamic amplitude on the machine whilst providing a stable and stiff base which may be supported by steel springs or other resilient devices. Many applications will operate quite satisfactorily with only an undamped steel spring support, but where system resonances may be excited to unacceptable amplitude due to the varying speed of the machine or transient conditions, damping must be incorporated.

Our range of steel springs and damper units for the support of machines are as diverse as laboratory balances and turbo generator sets. Although standard components are used, each system is individuality designed and analysed to ensure that the correct stiffness and masses are provided to permit proper operation of the mounted equipment. First introduced over 40 years ago, these systems are now used world over.
