TMC’s
low-profile 65 Series Floor Platform
Isolation Systems are designed for
larger, floor-mounted instruments.
These platforms effectively isolate
instruments weighing a few hundred
to tens of thousands of pounds and do so without the compromises
in stability normally encountered when isolating
instruments with a high center-of-mass.
Historically, we approached the
problem of a tall, top-heavy payload by combining our Gimbal
Piston™ Air Isolators with
“ lifthoods” and a massive floor platform. This lowered
the effective system center-of-mass and achieved
the required stability.
Increasingly, our floor platforms
are configured with our Stacis® Active
Piezoelectric Isolators in place of our
Gimbal Piston Isolators. The advantages of Stacis
over pneumatic isolation include:
The Gimbal Piston Floor Platform is still available and recommended in many applications. We will help you determine whether a Stacis or Gimbal Piston Floor Platform is best for you.
TMC works closely with instrument manufacturers to ensure that our platform design meets the instrument’s footprint, structural, and utility requirements. We have successfully isolated hundreds of different instruments and are often already familiar with the tool requirements. In most instances, you need only provide the tool manufacturer and model for us to recommend a solution.
