This article presents research on the correlation between vibrations of the ŁZKS 1600 stacker-reclaimer superstructure and the harmonic changes in loads in undercarriage supports. Investigations are focused on the change in center of gravity location caused by superstructure vibrations and its influence on loads acting on the elements of the undercarriage. The presented research and analysis of results indicate a clear correlation between dynamic behavior of the superstructure and the changes in loads acting on the undercarriage. It was shown that the harmonic nature of the changes in these loads is derived from the global vibrations of the superstructure, which cause a dynamic change in the position of the center of mass.
