A 1:20 scale model of the new bridge
type was built and fitted with type KMR force washers
in May 2013. This model was used to carry through different tests regarding assembly and operation. Since in this case the measurements were only taken to verify the FEM results
, cost-effective miniature force washers
could be used.
The original-size bridge
was installed in a gravel plant in late July 2013. It is made of steel and stabilized by four pre-stressed wire ropes. C6A force transducers
from HBM each with 1000 kN
measuring range were installed in all of the four ropes for monitoring of the pre-stressing force
during assembly and operation. Type AE301 industrial amplifiers
were used for evaluation
. Jakob Baader, Senior Project Engineer at Bitterli+Partner Ingenieure AG says: "HBM offers a very attractive price-performance ratio
and products that can also be used in harsh environments." The measurements were highly reliable and stable
. A vibration damper optimally adapted to the bridge will now be developed based on the acquired measurement data.
