FIELD: mining industry, movement of mining machine along rack or traction chain of conveyer. SUBSTANCE: hydromechanical drive of mining machine includes body, power cylinders, crankshaft and camshaft intercoupled by mechanical transmission, unit of distribution valves mechanically connected to camshaft, pressure and discharge lines. Power cylinders are joined on one side with the use of hinges to body and on the other side their rods are coupled to crankshaft which carries driving sprocket. Camshaft and its driving gear are joined movably for relative turn through 180 deg and registration in each extreme position. Turning mechanism is put on one end of camshaft. EFFECT: increased operational reliability of hydromechanical drive. 4 dwgr
