This paper presents results of analysis characteristics of vibroacoustic wawes of the dynamic equipment of mining shovels and classification of defects of rotating equipment on which is substantiated the use of methods of vibration control and non-destructive testing. A set of more than 60 diagnostic rules for automated detection of major damage to property on the basis of selective frequency bands warning systems for predictive maintenance of mining machines. The efficiency of an integrated diagnostic approach for evaluating the technical condition of the mechanisms in the parameters of mechanical vibrations. It is proved that only the widespread use of modern methods of vibration diagnostics and non-destructive testing allows early detection of equipment defects of mining shovels. This research revealed the basic laws of the changes in the technical state of the dynamic equipment such as draglines from the analysis of parameters of mechanical vibrations. The results of these researches demonstrate the need to move categorically repair and maintenance departments of industrial enterprises in the service system technology on its actual technical condition, a platform for the implementation of the basic elements of the concept which will serve as a designed complex of diagnostic rules detecting defects on the analysis of the parameters of mechanical vibrations.
