Cooper B-Line Pipe Hangers & Supports - Dixie Construction Products

HESL*/HES Type - Combination Spring & Neoprene Vibration Hanger
Use: HES Series Vibration Spring Hangers are
suited to isolate both high and low frequency
vibration generated by mechanical equipment. The
high deflection spring addresses the vibration while
the neoprene insert dampens noise. HES hangers
are recommended for critical areas and with vibration
sensitive spans.
Features: Color-coded spring for load
identification and double deflection neoprene
element. Loads up to 1500 Lbs. (6.67 kN),
deflections up to 2.50" (63.5). Options available
include: 30° rod swing; scale with pointer; and
positioning plate or pre-compressed spring to hold
equipment at fixed elevations (see bottom page 185).
Any or all of these options must be specified. Hanger
units are shipped assembled.
Typical Applications: Fan equipment, ductwork,
piping, suspended ceilings, etc. To be used in-line
with all thread rod for single and trapeze type
support systems.
Note: Vibration hangers should not come in direct contact with equipment being suspended.
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.
