A drive assembly of bucket wheel at the bucket-wheel excavator (BWE), as a rule, is a unit characterized by large force having huge torque and mass with structures in different arrangement including the support structures as well. Behavior prediction is of crucial importance in order to apply the right approach of operation and maintenance on gearbox, electrical engine as well for structural elements supporting this assembly. It is obvious that vibrations measured at distinctive points of the entire drive assembly and support structure represent the main prediction parameter. The measurement results are used to confirm mathematical model developed by means of finite element method, which is based on theory on flexibility, static and dynamical review for obtained results
