We grounded the motivation of students to develop and use catalogue in their work. Examples with family planetary reducers are given and the construction of safety over flow valve is discussed as well as its rotor eccentric crusher in mine industry. A 3D model of rotor crusher is presented with the catalogues numbers of crushing and flywheel head. We made computer investigation of repercussion plates of crusher and their static movement. The results are analysed and recommendation are made about improvement of construction. A conclusion about relationship between competitive power of products and quality of training in higher technical education was made.
