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.
