ROADHEADER AND CUTTER HEAD THEREFOR
20250314172 · 2025-10-09 ·

A transverse cutter head for a mining machine has an outer surface including a plurality of cutting tools. Tips of the plurality of cutting tools define a virtual contour line when viewed in a cutter boom longitudinal direction and a rotation of the cutter head is considered. The contour line is formed by at least four sections, namely a first section, a second section, a third section and a fourth section. The four sections are located adjacently in this order, wherein the first section is located closest to the cutter boom and the fourth section forms a side wall cutting area. The first section and/or the fourth section run substantially straight. Each one of the first section, the second section, and the third section has a pitch angle different from the pitch angle of the other two sections. A roadheader having such a cutter head is also provided.
