Abstract
The appliance for sinking vertical shafts, has a harness (1), with horizontal axes, of rotation, bearing a pair of rotary hewing heads (9). These are mounted on carriers (3), for symmetrical movement in a vertical plane, between a centre position adjacent the shaft axis, and a peripheral position against the shaft side. There is an adjustment system for raising and lowering the hewing heads. The heads are distributed so that the horizontal components of the operative reaction forces cancel each other out.
