  • The effect of cutting head shapes on roadheader stability

    05-09-2013 · In this study the effects of the cutting-head shape (spherical conical and combined heads) were investigated by applying this method to the stability of a longitudinal type roadheader. Turning around the vertical axis of the machine was found to be the most critical stability state.
