Seismic Mountings

Spring isolation systems offering multi-directional flexible restraint to limit equipment movement under conditions of seismic disturbance.

In normal operating conditions, the mountings provide vibration isolation generally 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. At the maximum restraint capacity of each mounting type, movement is limited to less than 12mm along any major axis.

Light Duty, CM Series Types CSM, CLM, CWM, CWDM, CDM, CTM General purpose mountings offering static deflections to 75mm, and rated to the static force of: AS 1170.4 for application up to maximum equipment load range in all Australian Seismic zones NZS 4219 for application with reduced equipment load range in New Zealand.
Installed as two configurations, outrigger brackets was used on pumps and aircompressors, or as conventional under-base mounting for fans, air conditioners, and similar equipment. Static deflections: 25 to 75mm Load range: 10 to 1275kg
Medium Duty, EM Series Types EML, EMW, EMD, EMT, EMQ General purpose mountings with static deflections to 100mm and rated to static force restraint requirements of: Australia, under conditions where additional safety factors may be necessary (i.e. where static force restraint in excess of AS1170.4 is required), and NZS 4219 for applications up to maximum equipment load range in all New Zealand Seismic zones, and International seismic codes
Heavy Duty, XM Series Types XLM-2, XWM-2, XWM-4, XDM-2, XTM-2 Low profile, high load capacity mountings offering static deflections to 75mm, Rates for static force capacity in excess of the requirements of AS1170.4 and NZS4219 for seismic zones in Australia and New Zealand respectively and for other designated zones internationally. Specifically used for the mounting of generator sets and chillers, or where high shock loads may occur.
Independent Seismic Mounts, SR Series Types SR1, SR2, SR3, SR4 The mounting used to not incorporate seismic restrain capacity as an integral feature - mountings such as elastomeric isolators, high deflection high capacity spring mountings or air mountings
Cable restraints Used in conjuntion with spring or rubber hangers for the seismic restraint of suspended piping and equipment. Installation is generally undertaken when all piping and other equipment is in position and fully loaded.
