Vibration isolators for equipment which is
subject to load variations, wind loads, or large external or torquing forces
shall consist of large diameter, laterally stabile steel springs assembled into
formed or structural steel mounting assemblies designed to limit vertical
movement of the supported equipment.
The assembly shall incorporate a bottom load
plate and restraint assembly, a top load plate, a leveling and restraining
bolt, and an internal noise isolation pad.
Isolators shall be provided with means for
anchoring to the supporting structure and for attachment to the supported
equipment.
Spring elements shall have a lateral
stiffness greater than 0.8 times the rated vertical stiffness and shall be
designed to provide a minimum of 50% overload capacity.
Springs shall be selected to provide
operating static deflections shown on the Vibration Isolation Schedule or as
indicated on the project documents. Springs shall be color coded or otherwise
identified to indicate load capacity.
Vibration isolators shall be Model FRS, as
manufactured by Kinetics Noise Control, Inc.
