The large industrial cranes carry out transportation operations in the presence of a large impact load and mechanical stresses acting on the crane’s structure. The safety and efficiency of crane operations can be improved through providing the continuous structural health monitoring of crane’s equipment and components. Advanced non-destructive techniques can be employed for inspection of cranes during operation, that leads to reduce the down time costs and increase the safety confidence in the monitoring process. Magnetic flux leakage methods of non-destructive inspection are widely utilized in identification of damaged areas in steel structures. However, the traditional magnetic flux leakage techniques are more appropriate in detecting cracks, but not sensitive to the detection of micro-defects. Metal magnetic memory is a relatively novel method of detecting the micro-damage in ferro-magnets due to the stress concentration. This method proved its effectiveness in early identification of the possible defect location. However, the method is preferable to off-line inspection due to the presence of operational variations in on-line measurements that can cause false indications of damage. In this paper, the problem of continuous inspection of crane’s frame using the metal magnetic memory method is considered. The influence of operational variations on the self-magnetic flux leakage signal is investigated and quantitatively analysed based on the experimental results obtained on a laboratory-scaled overhead travelling crane.
