The reliability you need for the productivity you demandWhen you need the lowest cost per meter drilled and blasted, Komatsu rotary drills deliver. Featuring rugged and reliable rotary carriages and enclosed boxer style masts, these machines provide ample torque and bit loading through the tough rock conditions. With maximum bit-loading ranges from 77,000 to 150,000 lbs. (68,039-34,927 kg) Komatsu offers a range of rotary drills for a variety of capacities and applications.
Features may include:
Robust, solid boxer-style mast construction- To help reduce maintenance time and increase structural reliability, we've engineered an innovative solid boxer style mast.
- 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.
- 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.
- Increase drill utilization, helping to reduce operator inefficiencies and overdrilling. Single and multiunit high-precision GPS (HPGPS) remote control operation for effective control.
- The versatility to allow operators to perform multiple functions with a single drill rig with automatic mast positioning and adaptive auto-leveling.
