Date Jun. 16, 1988.The openpit mining device includes a cantilever arm which is swivellable around a horizontal axis and carries a support or tool carriage. The support or tool carriage is shiftably supported in a transverse relation to the longitudinal axis of the cantilever arm and has tools rotatably supported on it. For this purpose, the head of the cantilever arm carries a rod-type guide and the tool carriage or support carries a rod-type guide. The guide rods are mutually interconnected with interposition of an intermediate carrier. The shifting drive is provided by hydraulic cylinder-piston-aggregates which are arranged between the intermediate carrier and the head and between the intermediate carrier and the support.
