Abstract

1,081,225. Advancing mine roof supports. HOESCH-BERGBAUTECHNIK G.m.b.H. Aug. 11, 1964 [Aug. 23, 1963], No. 32705/64. Heading E1E. An advancing mine roof support comprises two parallel frame units advanced selectively by a device 1 therebetween, each comprising two (or more) props 2- each one being mounted for tilting movement on a foot-plate 3 and arranged parallel to the direction of advance, - each frame being connected to the device 1 by a respective stub axle 4. Each frame includes pre-tensioned leaf springs 5, 6 between the stub axle 4 and the props 2, of adjustabe rigidity. The springs 5, 6 are adjustable in position to vary the distance between the props 2 of each frame.
