Abstract

1,213,857. Advancing mine roof supports. KLOCKNERWERKE A.G. 6 March, 1968 [7 March, 1967], No. 10840/68. Heading E1P. In an advancing mine roof support comprising two frames A, B arranged in parallel, one frame 13 has a bar 10 disposed parallel to and adjacent its elongated foot portion whilst the other frame A has a strap 14 extending transversely thereof which strap is attached to a slide 12 able to move along the bar and has a heel part 15 adapted to make sliding contact with the foot portion of the frame B thereby limiting relative tilting movement between the frames. The frames are advanced by rams 21, 22 which are disposed as shown and coupled to a conveyor by haulage ropes 23, 24. An advancing jack may be disposed within the rod 10 and the slide may have a venturi-shaped bar therethrough. To allow a degree of swivelling, see Fig. 4 (not shown).
