The “HAT” type pylon rotators are used for heavy
duty DUT measurement.
This unique hat-shaped rotator is positioned on top
of the pylon and provides a mounting interface on its
bottom fl ange to allow the rotator to fi t inside the DUT.
Fitting the rotator inside the DUT minimizes the
rotator’s interference in the measurement results.
Above a 20 ton DUT load, the mounting interface is on
top of the rotator.
