“There are three crucial factors that we need to address and improve in all of the 400i-class applications: safety, productivity and process control,” Naapuri says.
The upcoming relaunch includes Sandvik DL432i and Sandvik DU412i longhole drills and Sandvik DS422i cable bolter, as well as an extensive automation update. Sandvik launched its first 400i-class drill, Sandvik DD422i development jumbo, in 2013 and subsequently expanded with the electric Sandvik DD422iE. “On top of that, we also make use of the new possibilities created by big data and mining automation.”

A common denominator across the series it says is strong symbiosis of sound engineering design and advanced automation solutions.”The Sandvik 400i class offers a well-rounded package for mining and construction in drifts and tunnels 4 by 4 metres or larger: development drills for mine development, tunnelling jumbos for underground construction, cable bolters for mine safety and rock reinforcement, and longhole drills for production drilling and service support.”“While the product development for this drill family is ongoing, we particularly want to address the significant productivity, cost-effectiveness and sustainability challenges the mining industry faces today,” says Jukka Naapuri, Product Manager for underground longhole drills at Sandvik Mining and Rock Technology. In response to several current needs and trends in underground mining, Sandvik Mining and Rock Technology has relaunched and upgraded its 400i-class drill family.
