Case Study: Kalari HSE reduces emissions and fuel use with Cummins QSK60 Advantage solution

Kalari HSE - Customer Case Study

Kalari HSE, a mining contractor operating in Australia’s Bowen Basin, wanted to reduce carbon and diesel particulate emissions while also lowering operating costs at its South Walker Creek coal mine. To do this, the company looked for a more efficient power solution for its Komatsu 830E haul trucks and chose Cummins QSK60 engines.

Cummins implemented its QSK60 “Advantage” rebuild upgrade program, replacing the old fuel system with Modular Common Rail technology and adding combustion improvements from its Tier 4 engineering programs. The result was a 63% reduction in diesel particulate emissions, a 3% cut in fuel consumption across six trucks, and more than 510,000 kilograms of CO2 saved annually, while also extending life-to-overhaul from 22,000 to 30,000 hours and reducing total cost of ownership.
