Battery-driven tramming – zero emissions
Using the onboard battery, Sandvik DD422iE produces zero emissions while tramming, contributing to the health and safety of underground workers. The elimination of diesel particulate matter (DPM) and other engine emissions may even help reduce the mine's ventilation costs and lower its energy consumption.
No diesel – improved safety, lower costs
Eliminating the diesel engine potentially even reduces the need for expensive infrastructure to transport diesel fuel to the underground mine. Freedom from fuel logistics provides major cost-savings potential and further improves the safety of underground operations.
Recharge by drilling and tramming – uninterrupted productivity
This rig's power system uses the existing electric infrastructure during drilling to recharge the battery and load the battery while tramming downhill, thanks to the regenerative brake system. There's no need to worry about power outages, as this rig keeps on going – from one mine site to the next, thanks to the multi-voltage-compliant universal electric system.
Peak power management – energy reserve for max loads
By drawing reserve power from the batteries during peak loads during drilling, the jumbo's intelligent power management system helps meet ever-increasing productivity requirements despite limited underground electric power capacities.
3 ways Sandvik DD422iE will improve your mining operation:
- Helps reduce overall diesel particulate matter (DPM), nitrogen oxides (NOx), and carbon dioxide emissions in your mine, creating an improved underground environment for workers.
- Charges your batteries during the normal drilling cycle and downhill tramming.
- Better drilling performance with our active power compensation system.
