The 285XPC rotary blasthole drill provides up to 53,524 kg (118,000 lbs.) of bit loading, specifically designed for 229 and 311 to 349 mm hole diameter applications. This drill is used in copper and iron mines worldwide.

Powerful pulldown

  • Top-drive, rack-and-pinion pulldown has fewer wearing components requiring maintenance, contributing to better machine availability
  • Powerful rotary carriages provide ample torque and bit loading to break through the toughest rock conditions

Superior propel 

  • Mainframes and crawler frames are built for maximum strength and stand up to the most challenging hard rock mine conditions
  • Rugged crawlers and powerful hydrostatic propel drives deliver manoeuvrability, gradability, and fast set-ups

Rugged masts

  • Drill mast is designed for high-cycle fatigue resistance, resulting in less downtime and lower costs for crack repair
  • Mast, constructed of high-strength alloy steel, provides maximum rotary carriage and drill string support

Excellent operator visibility

  • Operator's cab provides a clear, unobstructed view of the drilling area, including the areas surrounding the drill
  • Full windows, coupled with video cameras, ensure that your operator has maximum visibility during drilling and propelling operations
  • Operator's chair can swivel to face the travel direction, allowing safer repositioning

Protective and productive operator environment

  • FOPS Level II-certified structure and shatter-resistant glass protects your operator during harsh mining conditions
  • Operator controls are located within easy reach to allow for maximum productivity

Superior extreme environment capabilities

In addition, the 285XPC has options available that make it ideal for some of the toughest mining conditions in the world:

  • Arctic conditions: equipped with the necessary heaters and insulation to protect both your operator and the drill in temperatures that reach -40°C (-40°F)
  • High altitude: has the power and air capacity to maximize productivity in altitudes up to 4572 m (15,000 ft.)
