Sandvik DD421 Record Breaker
Sandvik DD421 boosts productivity in mine development and small scale tunneling. Powered by new efficient rock drills, robust booms and a wide selection of feeds, it offers an optimal coverage of 60 m2.
The new carrier layout is specifically designed for safe access to all service points, and all daily maintenance is conducted at ground level. Adjustable drilling settings of the new hydraulic control system optimize drilling performance in any conditions. To ensure highly accurate drilling results and enable valuable feedback information of the drilling process, the drill rig can be equipped with TCAD™ instrumentation.
The DD421 is the successor to the proven Sandvik DD420 drill rig, with even greater serviceability, and improved performance. The modular design makes training, operating and maintenance of the fleet easier.
Key features • Drilling booms providing 8 – 60 m2 cross sections • 25 kW rock drills • TCAD/TLOG instrumentation • Fast and efficient mobile carrier
