Sandvik has launched the DS422iE, its first battery-electric cable bolter designed for underground rock reinforcement using cement-grouted cable bolts. The new machine expands Sandvik’s battery-electric underground drill lineup, eliminating the need for a diesel engine in underground applications.

The DS422iE utilizes a lithium-iron phosphate (LFP) battery chemistry, selected for its enhanced safety profile in underground environments, while aiming for high productivity and equipment utilization. The electric driveline, combined with full automation, also reduces fuel consumption, heat and noise compared to diesel alternatives.

The rig is capable of installing up to 25-meter cable bolts with multiple steel strands per hole. It is equipped with an on-board automatic cement mixer and a 600-kilogram cement silo, which Sandvik says reduces manual handling and refilling between installations. Charging While Drilling technology enables operation for up to four hours off-grid, facilitating full-cycle drilling where electrical infrastructure is limited.

“Sandvik DS422iE is the first battery-electric cable bolter on the market, marking another significant milestone in Sandvik’s battery-electric vehicle competencies,” said Ari Kopperoinen, product manager, rock support drills at Sandvik. “The ability to continue rehab work off-grid using battery power is a transformative feature for mines with an unstable electrical grid. Combined with our industry-leading battery technology, operations have never been more productive or independent.”

DS422iE carries over features from the diesel-powered DS422i, such as one-hole automation, repeatable bolting accuracy, tele-remote and full fan automation and a cabin with improved visibility. The system is also compatible with Sandvik’s digital tools, including iSURE, Sandvik DrillConnect, Digital Driller, and My Sandvik remote monitoring systems.
