AU-DO
The AU-DO rocker suspensions have been mainly devel-
oped for the channel support in continuously loaded, base
frame excited two-mass oscillation systems with unbalanced
drive (energetic amplification). The base frame m
1
is excited
by means of unbalanced motors and the spring accumula-
tors of the AU-DO rocker suspensions amplify the marginal
frame oscillation amplitude into a considerable throw ampli-
tude on the conveying channel m
2
. The base frame is ideally
supported on ROSTA Oscillating Mountings Type AB. These
systems are characterised by low, hardly measurable resid-
ual force transmission into the substructure and are therefore
suitable for installation on steel frameworks and interme-
diate floors in processing buildings. Additional customer
benefits are the low-noise operation, the low involved motor
power and the simple installation.
The AU-DO elements are available in 5 sizes.
We will be glad to calculate your specific system, please ask
for our relevant questionnaire.
