Stingers pressurization upgrade DL432i

Sandvik has developed a new modification kit for stinger pressurization to improve the drilling module stability of the DL432i.

  • Description

    Stability of the drilling module during long hole drilling operation is a critical factor to insure hole accuracy and optimal drilling performances. This means the stingers efficiency is a very important topic. Improper anchoring of the drilling module can also generate important vibrations and unexpected movements that could damage or reduce the life of the module.

    Sandvik has developed a new modification kit for stinger pressurization to improve the drilling module stability of the DL432i. Continuous pressure holds the stinger better on the rock during drilling.

  • Advantages

    -Improve the drilling module stability.
    -Avoid unexpected vibrations and movements

  • Customer values

    -Improve drilling accuracy and performance
    -Reduce vibrations and risk of unexpected movements that could damage the drilling module.
