Abstract

1460434 Mining machine haulage JOHN LAING & SON Ltd 5 April 1974 [18 April 1973] 18788/73 Heading E1F A mining machine 10 is hauled along a seam 14 by driving a machine-mounted endless chain 50 and bringing the chain into engagement with a track 55 by means of a saddle clamp (23 Figure 3 not shown). The endless chain is driven by a drive sprocket 18 and is tensioned by an adjustable sprocket 24. The track 55 comprises units 53a-53d, each unit having plates 61-63 mounted for limited sliding movement on a respective spill plate 52a-52d. The plates 63 have the track 55 and a chain profile 70 formed therein, the latter being connected to a similar profile on an adjacent unit by a chain link 71 to ensure accurate spacing of the units. The saddle clamp (23) includes a movable block 27 having a guide slot 33 and a saddle member (45) which slidably engages the plates 61-63.
