Shaft drill rig (3 arms)

Drilling tasks during shaft sinking operations:

 

  • blast holes

  • prospecting holes

  • injection holes

  • water drainage holes

  • pneumatically driven

  • adaptable to various shaft diameters

  • drill feed systems for various blast hole lengths (up to 4,800 mm)

  • foldable like an umbrella to create a minimum diameter for transport through the shaft platform to the shaft floor

  • rapid erection at shaft bottom

  • rapid and accurate positioning of drill feeds to blast hole pattern due to stable set up by bracing elements

  • integrated lubricating system for drifters and pneumatic feed motors

  • easy maintenance due
