The results of vibration measurements at characteristic points on the belt conveyor drive of bucket wheel excavatorSRs400 manufactured by Takraf are presented in the paper. The operating processes (transport of material on the belt conveyor) belong to the category of impacts, such as fitting, acceleration, sudden loading, and the like, which are extremely pronounced in mining machinery. For monitoring purposes, measurement was undertaken in all three directions, upon overhaul and after 11,850 hours of operation. Movement, speed and acceleration of oscillations were plotted using measured data and the effect of the rear connection of the electromotor mount support on its proper performance was determined.

Extensive vibrations of the belt conveyor drive electromotor of a bucket wheel excavator as a result of intensified wear-and-tear of its mount support
