100% Electric tramming

DD422iE produces zero emissions while tramming due to the onboard battery’s electric energy, improving the health and safety of all underground workers.  

Reduce reliance on diesel

Eliminate diesel particulate matter (DPM) to lower ventilation costs and energy consumption. Reduce the need for expensive infrastructure to transport diesel underground. 

Energy reserve for max loads 

Draw reserve power from the batteries during peak loads while drilling with the jumbo’s intelligent power management system. Meet ever-increasing productivity requirements despite limited underground mine electric power capabilities.

Drill anywhere in the world

The multi-voltage system creates flexibility to operate anywhere in the world. The jumbo operates in networks ranging from 380V - 1000V and both 50 and 60Hz, meaning you can move your drill from one country to another with ease.

Electrification

More productive, powerful and better for workers' health

"Every mine has a capital purchase or a maintenance replacement coming up in the next few years, and they would be missing out if they decided not to investigate or pursue battery-electric technology."
