Sandvik have developed an auto mode feature allowing an operator to simply set the appropriate machine parameters and starts the drill in auto mode. Throughout operation the Sandvik DE140i automatically compensates for changes in drilling conditions to optimize drilling within the pre-set parameters.

Advantages

• All operating commands in auto mode are executed automatically from the touchscreen
• The automatic functions enable the operator to complete other tasks during the drill cycle or set to drill a core run during shift change increasing productivity
• Individual user profiles permit saving settings for a particular drill site
• Appropriate parameters can be selected to suit less - experienced drill crews
