Boomheader |
A relatively soft-rock mining machine that can mine selectively and cut any shape or size of tunnel by use of a cutting head on a hydraulically controlled boom or arm that is generally centrally positioned on the unit and extending cantilever-fashion in front of the machine in such a way that it can be vertically raised or lowered or swung in an arc from side to side.
