Abstract (en)
A tunnelling, ripping or heading machine comprises a machine body and excavating means (20) connected to said body by a mounting arrangement (15). The mounting arrangement (15) is movable, relative to the body of the machine, in a first direction, under manual control. Such movement automatically activates movement in a second direction so that a predetermined excavation pattern results. A method of excavating using such a machine is also described.
