Seismic Spring Mounts
SSLFH-X Series Seismic Spring Mounts
Light duty seismically rated spring mount.
Applications – Seismic
- Fans
- Pumps
- Air Compressors
- Air Handling Units
Capacity
- 5kg – 95kg
Deflection
- 25mm
Options
- SAST Seismically Rated Anchors
Specification
Restrained spring mountings shall have an SSLFH-X mounting as described in SSLFH-X Specification, within a rigid housing that includes vertical limit stops to prevent spring extension when weight is removed. The housing shall serve as blocking during erection. Installed and operating heights are equal. Restraining Bolts shall have a neoprene bushing between the bolt and the housing. A clearance of 6mm shall be maintained around restraining bolts and the bushing so as not to interfere with the spring action. Limit stops shall be out of contact during normal operation. Since housings will be bolted or welded in position there must be an internal isolation pad. Housing shall be designed to resist all seismic forces. Mountings shall have an OPA pre-approval from OSHPD in the state of California certifying the maximum certified horizontal and vertical load ratings. Mountings shall be type SSLFH-X as manufactured by Mason Industries, Inc.
