<p>The mining machine can serve a dual function, as a road header or as a continuous miner. The machine has a turret (14) into which a road header assembly can be directly pivotally mounted. Alternatively a continuous miner cutter assembly can be pivotally mounted on the turret, indirectly via transversely disposed pivot extension brackets (45) which are firstly mounted on the turret to extend the pivot axis forwardly of that of the road header assembly. Each bracket has three bores (46 - 48) in triangular disposition, two of which (46, 47) fixedly connect the bracket to the turret while the third bore (48), forwardly of the others provides the pivotal connection for the parallel arms (40) of the continuous miner.</p> |
