Reduction of degrees of freedom of narrow arm longwall shearer loader by Guyan's method is presented in this work. Model was made as 3D model, and for modal analysis Ansys program was used. Finite element method enabled determination of freąuencies and shapes of free vibrations of the system, before and after the reduction of degrees of freedom. In the aim of comparison of the elaborated models the MAC criterion was used.
