Positioning laser relocation for Sandvik DL421

To enable both generations of longhole drill rigs to operate with the same wall marking, Sandvik has designed a kit to change the location of the lasers on the DL421.

  • Description

    Sandvik longhole drills use lasers to position with accuracy the machine’s carrier in the drift, using marks drawn on the walls by mining Engineers. The distance between the drilling line and the lasers has changed between the older DL421 and the new generation DL422i and DL432i drill rigs.

    To enable both generations of longhole drill rigs to operate with the same wall marking, Sandvik has designed a kit to change the location of the lasers on the DL421. The lasers are now installed in the front mudguards of the machine, instead of on the boom tilt pins.

  • Advantages

    -Enables DL421 or DL422i and DL32i to use same positioning marking to navigate.

  • Customer values

    -Reduce the risk of error is the positioning of the longhole drills.
    -Ease the planning work.
