Step 2 stops at the position of the device. Then, by stopping the steps 2, it is possible to easily identify the operating device that generates the abnormal sound, and maintenance work such as repair or replacement of the operating device is performed.

Then, proceeding to step 113, if the abnormality display means 16 is not deenergized, the procedure returns to step 111, and if the abnormality display means 16 is deactivated, the inspection work of the first operating device which generated the abnormal sound is completed. . Step 111
And when the abnormal position operation button 19 is pressed, the step 2 is moved to the position of the second operating device that generated the abnormal sound.
Is stopped, and maintenance work is performed in the same manner as in the case of the first operational device that has generated the abnormal sound. When there is another active device that further generates an abnormal sound, the abnormal display means 16 is not deenergized, and the abnormal position operation button 19 is pressed again to repeat the operation of the step 2 and the maintenance work. It is.

As described above, the receiving device 9 receives the acoustic data of the transmitting device 3 of the steps 2 circulating in the main frame 1. Then, when the sound reception data exceeds the reference sound data, the abnormality display means 16 is activated. As a result, the presence of the active device that generated the abnormal sound and the position of the active device are displayed by the abnormality display means 16.
