Spring isolators shall be comprised of two interfacing but independent elements; a coil spring element and a seismically rated housing. The spring coil element shall be comprised of one or more coil assemblies having all of the characteristics of freestanding coil spring isolators as specified in the vibration isolation portion of the specification. The seismically rated housing shall be sized to meet or exceed the force requirements applicable to the project and have the capability of accepting coils of various sizes, capacities, and deflections as required to meet the desired isolation criteria.
All spring forces will be contained within the coil/housing assembly and under no seismic load condition shall the restraint anchoring hardware be exposed to spring -generated forces.
The restraint element shall incorporate a steel housing with elastomeric elements at all dynamic contact points. The restraint will allow ¼" motion in any direction from the neutral position. All elastomeric elements shall be replaceable.
To ensure the optimum anchorage capacity, the restraint will have an overturning factor (the ratio of the effective lateral snubber height to the short axis anchor spacing) of .33 or less.
The leveling nut or screw shall be accessible for adjustment with the use of a pneumatic or electric impact wrench.
The spring element shall be replaceable without having to lift or otherwise remove the supported equipment.
The isolator/restraint shall be Model FMS as manufactured by Kinetics Noise Control.
