Abstract

1379417 Mine roof supports OESTERREICHISCH-ALPINE MONTANGESELLSCHAFT 14 Dec 1972 [14 Dec 1971] 57663/72 Heading E1P [Also in Division F1] The props 2, 3, 4, 5, Fig. 1, of a mine roof support are moved into a position perpendicular to a floor frame 6 by claws 8, 9, Fig. 2, arranged on opposite sides of an abutment 13 and moved towards each other by a hydraulic ram 17, 18, 19, Fig. 4, provided with a pressure relief valve 24. Claws 8 are attached to the ram cylinder 17 and claws 9 to a piston-rod 19 by a pin 20 which slides in slots 21 in tongues 15, 16. The latter are attached to the cylinder 17 and guided for sliding movement by members 10, 11. The claws are moved towards each other until their faces 23 are in contact with opposite sides of the abutment 13.
