3.4SRMT-4-350 Spring Isolator/Restrainer
SRMT/F series are heavy-duty seismic restrained mounts with unique sliding channels designed to withstand lateral loads in combination with vertical loads.
Vibrasystems isolators are tested and certified to ASHRAE 171-2017 for wind and seismic load resistance using cyclic loading in multiple directions. This protocol is more suited for a variety of applications than the OSHPD OPM program, which is only for seismic loads and is intended to provide attachment details for specific equipment, with limited application to other equipment.
Using the seismic and wind capacities in the Vibrasystems certification, a consulting engineer can select the proper isolator based on the demand forces calculated for any configuration of isolators. This gives the engineer flexibility to use more or larger isolators as needed to meet the load demand.
There are two available configurations:
- SRMF: flat top with an inside leveling adjustment feature
- SRMT: bolted top with leveling adjustment feature
HVAC equipment, fan air circulation systems, compressors, pumps, chillers, AC units, cooling towers, inertia bases, etc.
a) 350 Spring: 3” Outside diameter x 5” Free Length.
b) 140 Spring & 170 Spring: 2” Outside diameter x 5” Free Length.
c) 400 Spring: 3” Outside diameter x 5.75” Free Length.
d) 150 Spring: 2” Outside diameter x 5.75” Free Length.
e) Rated load is the maximum load recommended.
** Spring 148 at rated load has 40% additional travel to solid load.
