The P&H 77XD blasthole drill, with 77,000 pounds of max bit loading capacity, can be configured for rotary or hammer drilling, diesel or electric power, and single- or multi-pass drilling. This machine is designed to deliver an up to 10% maintenance and repair cost advantage and up to 5% availability advantage.

Several other smart features are available for the drill to facilitate improved cycle times, including enhanced auto drill and electronic load sense control. The 77XD is compatible with our new high-precision GPS tele-remote operation console and automation solution, which includes features such as geo-fencing, auto navigation, obstacle detection and mitigation, Hawkeye 360 camera system, and more.

Designed for productivity

  • Single-pass angle drilling with automatic mast positioning and adaptive auto leveling allows operators to perform multiple functions with a single drill rig
  • Propel with mast and carriage up, enhanced auto drilling, and automatic pipe and bit handling reduce drilling cycle time
  • Auto navigation increases precision of hole location with drill pattern

Designed for ease of maintenance

  • Robust, solid mast construction with simple rack and pinion design reduces maintenance
  • Patented pipe handling liners aid collaring; horizontal mast storage extends life of drill string
  • Optional mast access service platform allows easier inspection and maintenance of mast and top portions of deck

Designed for zero harm

  • Major components are integrated  into the chassis for lower center of gravity and increased stability
  • Cab designed for improved visibility, increased lines of sight, noise reduction, and automatic dust suppression
  • "Point of use placement" for hydraulics places the tester next to the function for increased awareness
