Based on the wavelet packet theory, the vibration signal of the hoist spindle is analyzed in time-frequency domain. The information of specific frequency band is used to diagnose the fault and the correctness and validity of the method are proved by analyzing the experimental data. This study provides an effective method to deal with the vibration signal of the hoist spindle and then to carry out fault diagnosis.
