Vibration damping of ultra-light belt conveyor galleries

From the model to full implementation

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 HBK 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: "HBK 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.
