Ultrasound measurement on slewing ring and expertise after replacement
For years, the reclaimer at a paper mill in north-western France had worked reliably, pivoting on three pinions mounted on reducers.
The reclaimer is used to collect wood chips from a pile and convey them by buckets. However, quite unexpectedly, the structure supporting this equipment collapsed. Fortunately, the company had implemented a monthly preventive maintenance program to monitor the condition of these slewing rings.
It was at this point that the company made a key decision. They decided to rely on technology to assess the severity of the ring’s breakdown after the collapse. They used an ultrasound measuring device (SDT340), the only technology that could provide an in-depth analysis of the situation. Reference measurements taken prior to the incident were retained to enable the current state to be compared with the initial state.
