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

Vibra Trol ® 182
HSL*/HS Type - Vibration Spring Hanger
Use: HS Series Spring Hangers should be utilized
to minimize damaging vibration from suspended
low frequency equipment (below 1200 RPM).
Frequency below 600 RPM require springs with
deflection 2.0” (50.8) or greater. Hangers also
absorb shock and limit noise in critical areas.
Features: Color-coded spring for load
identification. Loads up to 1500 Lbs. (6.67 kN),
deflections up to 2.10" (53.3). Spring assembly
includes neoprene washer for additional noise
isolation. Options available include: 30° rod swing;
scale with pointer; and positioning plate or precompressed
spring to hold equipment at fixed
elevations (see bottom page 183). Any or all of
these options must be specified. Hanger units are
shipped assembled.
Typical Applications: Fans, ductwork, piping,
suspended ceilings, etc. To be used in-line with all
thread rod for single and trapeze type support
systems.
Notes: 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.
