In several types of industries portal cranes are among the most critical installations. Yet, compared to more standard production assets like motors, pumps, fans or compressors, few portal cranes get the same treatment with regard to condition monitoring. Apart from the erratic operational conditions, the monitoring of drive motors and gearboxes is not all that different from the more common applications.
Monitoring the main wheel bearings is however a much bigger challenge. On top of the irregular operating conditions, one also has to cope with low speeds and very high ambient vibration originating from the contact of wheels and rails.
This case study shows the results of a successful monitoring program for portal cranes in the steel industry. Based on advanced high frequency monitoring techniques and the use of specific filters, bearing condition can be detected in a most reliable way. The application of wireless monitoring allows to further increase both the efficiency of the program, as well as to eliminate all safety risks.
1. Learn which monitoring techniques allow to successfully monitor low speed applications, even if ambient vibration poses additional challenges.
2. Learn the advantages of using wireless vibration monitoring techniques over portable vibration measurements.
3. Learn the advantages of using wireless vibration monitoring techniques over wired online monitoring techniques.
