BATTERY POWER UNDERGROUND
ground support and production drills with diesel-
free options. “The Boomer M-series face drilling
rigs have become a key piece of equipment for
mining and tunnelling applications. As part of our
commitment to continuous improvement, the
face drilling rig has benefitted from a
comprehensive upgrade, focusing on improved
safety, increased robustness, battery power,
automated functions and lower operational
costs.”
Thanks to its efficient and powerful electrical
motor and battery drivetrain, the Boomer M2C
Battery is able to perform long tramming in
challenging conditions without any emissions at
all. This means a safer working environment
underground with better air quality. At the same
time, the drill rig will charge the
battery while drilling the face so
there is no need to stop for
charging during tramming. All this
has been achieved without
changing the size and usability of
the machine. The benefits are
summarised as follows:
n The electric drive eliminates
diesel emissions and
minimises the need for
ventilation
n Thanks to the onboard
charging there is no need to
stop and charge. The Boomer M2C Battery
will charge during drilling and you can go

Using an efficient and powerful electrical motor
and battery drivetrain, Atlas Copco’s Boomer
M2C Battery is able to perform long tramming
in challenging conditions without any emission

n Large battery capacity and powerful motors
provide the ability to outperform diesel
machines in most applications
n Like all Atlas Copco equipment, the Boomer
M2C is automation ready. Add the functions
you need, when you need them.
The 100% electric Scooptram ST7 Battery from
Atlas Copco was unveiled last May 1; it is fully
battery operated. Battery power minimises the
need for mine ventilation, while offering the
same or better performance as diesel. That
reduces cost for infrastructure as well as the long
term operational costs.
"Compared to a tethered machine the battery
powered Scooptram has the flexibility of the
diesel but without the limitation of the trailing
cable. Cutting the cord means cutting costs and
adding flexibility to your underground
operations." With zero emissions and up to an
80% reduction in heat generation compared to
diesel power, the cost of installing ventilation is
minimised and the expensive refrigeration of
mines can potentially be eliminated in the long
run.
Each little detail matters when it comes to
designing a powerful, 7 t loader. Besides the
major change from diesel to battery Atlas Copco
says it also focuses on small, but smart functions
to create big savings. "For example, the
Scooptram ST7 Battery is also equipped with the
Atlas Copco unique traction control to increase
tyre life up to 30%. Together with the fact that
battery vehicles enable longer service intervals, it
increases overall up time and thus productivity,”
says Erik Svedlund, Global Product Manager -
Electric Vehicles - Underground Material Handling.
Operator comfort and productivity is a big
priority, which is why the Scooptram ST7 Battery
has excellent visibility and intuitive, ergonomic
controls in an ROPS/FOPS approved canopy for
safe ergonomic operations. The telematics
