Abstract

989,592. Mineral-mining installation. GEWERKSCHAFT EISENHUTTE WESTFALIA. Sept. 4, 1963 [Sept. 7, 1962], No. 34955/63. Heading E1F. [Also in Division B8] Each of the shifting devices provided in a mining installation for advancing a mining machine-guiding conveyer comprises a ram 10, 14 extending between the conveyer and a thrust block 11 and another ram 24 positioned above or below and directly or indirectly associated with the first ram so that by appropriate directional supply of pressurized fluid to the rams an oblique downwardly, or upwardly, or horizontal pressure can be applied to the conveyer as required to keep the mining machine cutting at a desired level. In the embodiment shown the ram 24 is combined with a damping unit 25 connected to a box structure 27 connected to the cylinder 10 of ram 10, 14 and slidable in the thrust block 11. The cylinder of the damping unit is openly connected to the pressure medium supply line of the rams 10, 14, 24.
