Housed - Fail Safe Spring Mount
HMLE*/HME Type - Housed 1" (25.4) & 2" (50.8) Deflection Fail Safe Spring Mount
(External Adjustment Bolt)
Use: HM Series Housed Spring Mounts are
utilized to isolate floor mounted equipment where
transmission of noise and vibration (below 1200
RPM) is apparent. This type of mount is most
commonly used to support equipment on upper
floors where structural deflection may occur.
Features: Telescopic two-piece cast iron housing to
stabilize spring where external motion may occur.
Slotted mounting holes on base with skid-resistant
pad. Mounting is facilitated by an adjustable leveling
bolt. (If bolt mount is not required, a skid-resistant
pad on top load surface is available in the
HMLT/HMT series shown on pages 178 & 179).
Springs are color-coded for load identification.
Housing components are isolated by rubber
acoustical pads. Larger capacity mountings are
available.
Typical Applications: Compressors, air handling
units, centrifugal fans, pumps and other similar
applications. May also be used as a vibration
dampening device for pipe risers.
Note: To ensure minimum effective vibration control, the spring mount must have a static deflection at least three times (3X)
greater than the floor spans deflection.
Spring devices are stable with a vertical and horizontal spring constant equal to one (Kx/Ky=1). A 50% additional run-out from
rated capacity to solid load is also characteristic of spring type isolators.
