This paper presents a method of determining modal characteristics of surface mining machines, which was used to establish the optimal number of buckets based on experimental studies of an existing machine. An experimental and operational modal analysis was implemented to determine the dynamic characteristics. Based on the technical requirements of the excavator, the quantity of buckets was set so as to avoid resonance during operation.
