Underground Roof Bolters
Operator-Up Roof Bolters
The Fletcher Model N3114-AD/E roof bolter is designed for bolting in stope conditions as narrow as 6.5’ (2 m). Drilling, resin insertion, and bolting is all done from the MSHA canopy operator’s basket that is mounted on a boom that lifts and swings to allow multiple installations.
N3120-AD/E man basket roof bolter is designed for installing commonly used roof bolts in the back or either rib, in headings from 8 ft. 10 in. (2.69 m) wide to 17 ft. 6 in. (5.33 m) wide and up to 18 ft. 10 in. (5.74 m) high. In difficult ground conditions, protective canopies over the carrier operators’ platform and man basket allow the operator to install bolts from safe, protected positions.
