Abstract
The mining machine can serve a dual function, as a road header or as a continuous miner. The machine has a turrent 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 provide the pivotal connection for the parallel arms 40 of the continuous miner.
