Features and benefits
Robust, solid boxer-style mast construction
To help reduce maintenance time and increase structural reliability, we've engineered an innovative solid boxer style mast.
Intelligent compressor control
This smart feature allows the operator to regulate the amount of air into the hole and helps manage power and fuel consumption. Effectively manage associated bailing velocity as well, which can help lower operating costs.
Auto-bit handling
The innovative auto-bit carousel helps to reduce bit change downtime. This feature also helps to flex into a new hole diameter quickly so operators can seamlessly adapt the drill pattern to quickly reach optimal fragmentation.
Drill automation system with remote control operation
Increase drill utilization, helping to reduce operator inefficiencies and overdrilling. Single and multiunit high-precision GPS (HPGPS) remote control operation for effective control.
Auto navigation capability with high-precision GPS (HPGPS)
This feature increases the precision of hole locations within drill patterns to elevate productivity. It also allows the movement of the drill between holes without the operator inside the cab.
Single and multipass angle drilling
The versatility to allow operators to perform multiple functions with a single drill rig with automatic mast positioning and adaptive auto-leveling.
