The paper deals with the problem of applicability of the metal magnetic memory (MMM) technique in the crane structural inspection and monitoring. The MMM method does not require the external magnetization of a structure that results in reduction of downtime of maintenance operations. Measurement of the intensity of the self-magnetic leakage signal can be an alternative to other non-destructive methods used for inspection of a large crane's structure and equipment. However, the complexity of the residual magnetization effect in the MMM technique is the problem with its application. Thus, the magnetic flux leakage behavior on the crane girder surface under different measurements and the crane's load conditions is analyzed based on the results obtained during experiments carried out on the overhead traveling crane.
本文探讨了金属磁记忆（MMM）技术在起重机结构检测与监测中的适用性问题。MMM方法不需要对结构进行外部磁化，从而减少了维护操作的停机时间。自磁泄漏信号强度的测量可以替代用于大型起重机结构和设备检测的其他无损检测方法。然而，MMM技术中剩余磁化效应的复杂性是其应用中的一个问题。因此，基于在桥式起重机上进行的实验结果，分析了在不同测量和起重机负载条件下起重机主梁表面的磁通量泄漏行为。
