ABSTRACT:
An anchor boring unit includes a base plate attached to a loading apron of a section advance machine, with a square tube swivelling around a vertical axis and movable by a hydraulic cylinder attached to the base plate. Another square tube is telescoped in the first square tube and a carrier attached to the upper end of tube can be lifted along the axis by another hydraulic cylinder. An arm attached to the carrier is movable by a third hydraulic cylinder around the axis and a plate attached to the arm is movable by the second hydraulic cylinder around another axis perpendicular to the first axis and to a boring axis. The anchor boring unit is capable of telescoping with two other cylinders for moving a mount in relation to the base plate and a boring machine in relation to the mount along a boring axis for seating roof anchors regardless of the section height and for seating wall anchors using the same boring unit as for the roof anchors.
