Dynemech Vibration Isolators
Allow Installation on Mezzanines & Upper Floors
As we know
today that builders save cost on modern floor slabs by making them thinner and
lighter and increasing column spacing. This tends to
make modern composite floors flexible and oscillatory. As a result, newer
buildings often do not dampen vibrations as well as older ones. Add to this the
noise and vibrations transmitted from nearby construction, manufacturing,
transportation systems or HVAC installations in the same buildings. Moreover,
high prices of real estate in modern cities have propelled air-tight
developments and compact construction which necessitate accommodation of large
number of high speed production machinery, office complexes and sensitive
machinery and equipments in the same buildings. Thus, mezzanine floors and upper floors are
added as a cost-effective way to increase square footage not only for storage
but also for production purposes. And of
course, vibrations are present in all operations involving machines and motion
due to inherent exciting forces. But, such excessive vibrations, may lead to
structural and mechanical failures, frequent breakdown and maintenance of
machines, human discomfort and noise. Hence, cost effective measures need to be
taken to reduce the vibrations within acceptable limits.

vibration dampeners provide lower natural frequency than the frequency of the
suspended floor (generally, the natural frequency of the pads should less than
half of the frequency of the suspended floor) so that resonance is avoided besides,
decreasing vibration amplitudes.
Dynemech will need to know how much the machinery is shaking. Then based on the machine shaking and other factors affecting the structural vibrations, we have the task of designing the vibration isolators for
the machinery to achieve the desired response on the roof.
We have successfully installed large industrial machines on mezzanine and upper floor including roof-tops:
