Orientation of the Unit Mounted Elastomeric Isolators

Updated

Issue:

In which orientation are the isolators placed underneath base rail?

 

Resolution

  1. Isolators should be oriented with the widest side perpendicular to the base rail in order for the mounting slots to be accessible.
  2. Secure the isolators to the mounting surface using the mounting slots in the isolator base plate. Do not fully tighten the isolator mounting bolts at this time.
  3. Align the mounting holes in the base of the unit with the threaded positioning pins on the top of the isolators.
  4. Lower the unit on to the isolators and secure the isolators to the unit with a nut.
  5. Level the unit within a 1/4" length and width (refer to submittal and IOM)
  6. Fully tighten the isolator mounting bolt.

The "ears" of the isolators that stick out past the rail will have a metal plate inside the rubber to allow for the bolts to tighten.

For installations where the "ears" will be floating over the edge of a rail/beam, a metal plate could be welded to the beam to support the entire isolator.
