Cummins Inc says it has commissioned its diesel-hybrid solution in partnership with one of China’s leading rigid mining truck manufacturers, North Hauler Joint Stock Co., Ltd. (NHL), demonstrating progress in decarbonisation for industrial customers.
The hybrid NHL NTH260, a 220-t payload mining truck, rolled off the production line in January and is headed to Baiyun iron mine of Baogang Group, China, to begin field testing in March. As a power solutions provider, Cummins’ optimised hybrid system allows the truck engine to be downsized from the previous 2,500 horsepower QSK60 to the current 2,000 HP two-stage QSK50.
“We’re excited to share this significant milestone in our journey to advance bridge technologies and provide our mining customers with innovative, practical decarbonisation solutions,” Jenny Bush, Cummins Power Systems President, who joined key leaders from Cummins Power Systems China for the commissioning ceremony in the NHL industrial park in Bautou, China, said.
The truck is expected to provide a leading total cost of ownership based on initial cost advantages, fuel efficiency and extended service life of the engine, Cummins says. Improved fuel efficiency directly correlates to emissions and greenhouse gas reductions. Advanced hybrids have the potential to improve fuel efficiency up to 30% dependent on the mine profile and advanced battery technology and controls integration, according to the company.
Haiquan Guo, General Manager, NHL, said: “Our partnership with Cummins spans 40 years and advancing the hybridisation of our equipment is another demonstration of what we can accomplish together for the benefit of miners globally.”
NHL produces trucks with payload range from 35 t to 360 t, with Cummins as the standard engine configuration.
Molly Puga, Cummins Power Systems Executive Director of Strategy, Digital and Product Planning, added: “We are intent on enabling multiple pathways to carbon neutrality for industrial markets, including both first-fit and retrofit solutions. It’s partnerships with our customers like NHL and Baiyun iron mine that will accelerate product availability in the market and make both near- and long-term carbon reduction goals attainable.”
In 2023, Cummins announced approval of unblended renewable diesel use in all industrial high-horsepower engines.
