UPDATED ELECTRIC DRIVE WHEEL LOADER
Built on a solid switch reluctance technology foundation leveraging more than 15 years of Caterpillar electric drive experience, updates to the Cat 988K XE deliver up to 10% faster downhill speed, improved rimpull and increased hydraulic breakout force for up to 5% better production. The updated design improves cycle times in load and carry applications, while an optional counterweight increases stability and offers faster manoeuvrability with these tasks. A new Go-Pedal for the 988K XE
features three dynamic breaking levels to give operators easier single right-hand pedal operation. Standard Tire Slip Prevention reduces tire slip and wear to increase tire life and lower owning costs
Achieving zero-emissions mining
reduction targets of more than 30%, with an ultimate goal of being net zero carbon by 2050. “A year ago,
Newmont, the world’s largest gold mining company, has announced a strategic alliance with Caterpillar to deliver a fully connected, automated, zero carbon-emitting, end-to-end mining system. Together, they will collaborate to create a safer, more productive mine, and substantially support Newmont in reaching its 2030 greenhouse gas (GHG) emissions
we announced industry-leading emission reduction targets because we understand the human contribution to climate change,” said Tom Palmer,
president and CEO of Newmont. “Now, we have furthered that commitment by announcing a new alliance with Caterpillar to address climate change by fundamentally changing the mining industry through the rapid development of a comprehensive all- electric autonomous mining system to achieve zero emissions mining.”
Creating the fossil-free mine
Three companies will jointly develop an electric trolley truck system for underground mining. ABB is working with mining company Boliden and mining and infrastructure equipment manufacturer Epiroc to develop and demonstrate an electric trolley truck system on a test track at Boliden’s Kristineberg mine in northern Sweden. The development project by the
three companies will enable heavy transportation with electric driven
battery vehicles and is expected to lower CO₂ emissions and improve the work environment at the underground copper-zinc mine. The system will build on Epiroc’s
zero emissions mining haul truck Minetruck MT42 Battery and is highly suitable for long haul ramps. It will feature a trolley pantograph that is to be connected to an overhead contact power line. ABB will provide the electric trolley truck system design, definition of standards and vehicle interface, as well as rectifier substation for the test track. The electrical infrastructure is part of the ABB Ability eMine portfolio of electrification and digital systems designed to accelerate the decarbonisation of the mining sector.

PRIVATE WIRELESS NETWORK DEPLOYED
Nokia has deployed an industrial- grade private wireless network with Antofagasta Minerals for Minera Centinela, to support secure and reliable operations at its copper mine in Chile. The network will allow the mining group to accelerate its digital transformation. Nokia industrial-grade private
wireless provides the high capacity and low latency required for mining companies to reliably and securely connect a variety of sensors, devices, equipment and vehicles, above and underground. The network, already in operation after being deployed in a record four months, will initially connect a fleet of autonomous trucks. Going forward it will support a wide array of operations as part of a five-year digitalisation plan.
