Rotary or DTH drilling up to 9” (229 mm) – Multi-pass

The DM45 is a crawler mounted, hydraulic tophead drive, multi-pass rotary drilling rig specifically designed for production blasthole drilling. It utilizes a diesel engine to drive the air compressor and hydraulic system. Electric-over-hydraulic controllers are ergonomically located so that the operator faces the drill centralizer while drilling. The DM45 is available in both high pressure and low pressure models to fit your tricone bit or DTH drilling needs. An angle-drilling option is also available.


Features & benefits

  • The new cab design allows a direct line of sight from the operator's seat to the drill table
  • The powerpack maximizes mechanical efficiency and isolates the components from drilling and propelling shock loads
  • The engine and airend combinations are designed to deliver optimum air and horsepower to meet the toughest drilling conditions without sacrificing power
