FIELD: mechanical engineering, particularly for mining.
SUBSTANCE: machine comprises undercarriage, load-bearing frame and jib-type executive tool. The executive tool comprises drive with reducing gear, jib frame with cutting chain, as well as jib movement and rotation mechanisms. The machine also has mechanism for transversal executive tool movement, which includes body, two horizontal bars fastened to load-bearing frame and triple hydraulic cylinder block. The executive tool is secured to mechanism for transversal executive tool movement by means of horizontal pins and may swing in vertical plane.
EFFECT: improved operational capabilities due to possibility to cut any number of slots in predetermined mine areas selected on basis of mining conditions.
