In 1982, the An Taibu mining area welcomed large-tonnage mining trucks equipped with Cummins KTA50 engines. This was the first time Cummins products entered this open-pit mine. At that time, more than 20 technical experts, overhaul engineers, and parts specialists from the United States, the United Kingdom, Australia, and other places crossed the ocean to escort the stable operation of the equipment of China Coal Pingshuo.
In 2005, the Chinese service team took over the responsibility of protection. On the basis of continuation of service, they actively went deep into the working conditions on the front line to tailor economic and efficient maintenance plans for customers.
Now, the main engines in the mining area are successively entering the "fourth major overhaul period". To ensure the production rhythm of the mining area and the reliable operation of the equipment, Cummins innovatively launched the "refurbishment" plan.
Refurbishment is not repair; it is "rebirth".
Entering the fourth usage cycle, the core components of the engines reach a critical node for deep maintenance. Cummins, in combination with the actual working conditions of China Coal Pingshuo, innovatively launched the "refurbishment" plan - from core component replacement, original factory process assembly, to whole-machine load testing, the entire process is benchmarked against the factory standards of new machines. Each refurbished machine is inspected in detail before leaving the factory, with power parameters and clearance all aligned with the technical requirements of new machines, ensuring long-term and reliable operation in heavy-load mining conditions.
The refurbishment plan launched by Cummins has solved our urgent problems. These refurbished engines have operated at full load for a long time, and the mining production rhythm is no longer disturbed by equipment failures. The two major problems of budget pressure and production risks have been solved simultaneously.
Original factory standards, no quality downgrade.
Combining the actual operating status of the equipment and the annual production capacity plan, Cummins tailored a scientific refurbishment admission mechanism for China Coal Pingshuo, reasonably arranging the refurbishment rhythm, making equipment maintenance and production plans synchronized. Throughout the refurbishment process, pure parts were used, ensuring the quality of refurbishment from the source.
As of now, this plan has been implemented and achieved results in the Pingshuo mining area of China Coal: a total of 15 QSK60 engines have been refurbished and overhauled, with a 6915% increase in hours.
With the continuous advancement of the refurbishment plan, the service life of the main equipment models in the mining area has been significantly extended. This not only ensures the reliable operation of the equipment but also helps customers save procurement costs, reduce maintenance costs, and improve attendance rates, achieving cost optimization throughout the entire life cycle.
The zero major failure operation data of the refurbished machines that have been in use for the past two years fully validates the technical reliability and economic feasibility of the Cummins refurbishment plan. We highly recognize Cummins' customized mining power refurbishment service.
Equipment has a cycle, but service has no end.
China Coal Pingshuo has been working with Cummins for over 40 years. Behind the trust is the full lifecycle service support throughout pre-sales and after-sales. The service team goes deep into the working conditions on the front line, combines the equipment maintenance plan of the customer, and jointly formulates scientific maintenance rhythms and high-standard refurbishment plans, reducing equipment downtime risks from the source.
At the same time, service technicians are stationed in the mining area, on call 7×24 hours. With exquisite skills and rich experience, equipment needs are addressed promptly, problems are solved quickly, ensuring mining efficiency.
In addition, Cummins also collaborates with the customer on-site to store and prepare spare parts, accurately grasping demands and providing timely supplies. This comprehensive chain of tailored, on-site response, and daily tracking services provides long-term and stable service support for the production operation of China Coal Pingshuo.
