Fletcher Model HDR is a versatile roof drill designed for general purpose bolting in up to 4.5 m high roof conditions. The model HDR features an operator platform, therefore rib protection tubes are possible and included. The boom lifts, swings, and extends to allow multiple installations from one chassis position. Heavy-duty Fletcher systems mean long life, maximum reliability and productivity.

For use in mines where:

  • Overcasts and falls require bolting in heights over 2.5 m
  • Production needs do not require a dual boom bolter
