The Fletcher CHDDR-4 model is a four mast roof drill. The bolter is run by two operators, each working two separate drill masts. With operator slide out platforms, operators can use detented controls to bolt the inside, outside, and toward the rib. Because the masts operate independently from each other, operators can perform separate tasks at the same time, maximizing production time.
