SEISMIC MOUNTS 

Integrated seismic mounts are designed to combine spring mount vibration isolation with multi-directional flexible restraint to limit equipment movement under seismic disturbance. 

In normal operating situations, the mountings provide vibration isolation equivalent to open spring mountings, but when subjected to physical displacements such as those generated by seismic forces, equipment motion relative to the supporting structure is restricted. 

Movement is limited to less than 12mm along any major axis at the maximum restraint capacity of each mounting type. 

When correctly selected, integrated seismic mountings will allow conformance to the design requirements of AS 1170, NZS 4219 and other International Seismic Codes. 

When undertaking final design, reference should be made to the relevant earthquake standards for the country concerned, and to the full Embelton Datasheets for application information, dimensions and installation details. 

For correct application, it is essential that static seismic force calculations are verified to ensure that the mounting design restraint capacities are not exceeded. Hold-down bolts must be adequate for the restraint application. 

We offer a wide range of seismic spring mounts for a full range of applications, as well as a rubber seismic mount, and independent seismic restraints. Also available are cable restraints, which are used in conjunction with spring or rubber hangers for the seismic restraint of suspended piping and equipment. 

Please refer to the selection guide over the page for correct selection of seismic mounting system and the relevant Datasheet reference.
