Description:
Model FHS seismic restrained spring
isolators meet specifications for Kinetics Model FDS isolators and include a steel
housing assembly to limit both lateral and vertical movement of the supported
equipment during an earthquake without degrading the vibration isolation of the
spring during normal equipment operating conditions.
Standard FHS isolators incorporate a steel housing which encloses a neoprene snubber. Depending on the load and seismic zone, an optional steel load spreader plate to distribute the load among concrete anchors may be applied. A neoprene pad fitted in series with the spring is provided. Equipment attachment is by way of a bolt screwed downward through the equipment foot. Removal of the isolator for servicing can be easily accomplished, as the isolator is not fitted with a protruding stud. In conformance with all current building code standards, the restraining system is designed to withstand a minimum 1.0 g acceleration force. Equipment motion is limited to approximately 0.2" in any direction, at the isolator.
Application
Kinetics Model FHS Seismic Control spring
isolators are recommended for noise and vibration isolation for mechanical
equipment located near critically quiet areas when there is a possibility that
the equipment to be isolated will be subjected to the external forces
associated with an earthquake. Model FHS isolators are used to reduce the
transmission of noise and vibration into supporting structures from supported
mechanical equipment. Motion during an earthquake which would otherwise
displace life support and emergency equipment is limited, and the equipment
remains in position. Anchorage of Model FHS isolators should be designed by a
professional engineer and isolators selected based on calculated anticipated
forces.
