Deep within the Kunming mines, the limestone rock layers have a dense structure and are hard in texture. In this tough working environment, the "powerful" mining owner, Mr. Gao, has already found a solution to reduce costs and increase efficiency by taking advantage of the gaps in the rock layers.
When the XEG-750GK hybrid excavator, equipped with the Cummins M15 hybrid-specific engine, was launched, Mr. Gao, as a "first batch of seed users", promptly purchased two units. Let's follow Mr. Gao to see how this hybrid excavator performs?
High efficiency and fuel savings - $200,000 saved annually
The mining operation is intense, and fuel costs are the major expense in mining operations. Mr. Gao admitted that choosing a hybrid equipment was due to the consideration of economy. The actual operation data was even more surprising.
"I have used the Cummins engine before, and my impression was that it saves fuel. This XG-75T hybrid excavator equipped with the M15 hybrid-specific engine has an average hourly fuel consumption of 42 liters, saving 5 liters per hour. Based on 5,000 hours of annual operation, with an oil price of 8 yuan per liter, the annual fuel savings are nearly $200,000."
The XG hybrid excavator equipped with the M15 hybrid-specific engine from XCMG can achieve high efficiency and fuel savings. The core lies in the hybrid "peak shaving and valley filling" technical advantage, which effectively improves the efficiency of engine fuel consumption utilization; at the same time, the equipment is equipped with an electric rotation system, which not only improves the return transportation efficiency but also realizes the energy recovery during the rotation process, further reducing energy waste.
Hybrid Advanced Technology
Dynamic Coordinated Energy Management Strategy
The M15 hybrid-specific engine specially developed by XCMG and Cummins achieves perfect synergy with the motor. Through better power coordination and dynamic matching strategies, it breaks through the power bottleneck of traditional systems and enhances both operational efficiency and maneuverability. At the same time, it is equipped with an electric reversing system that starts and stops faster and operates more precisely, significantly improving the smoothness of load operation. The efficiency advantage in mining loading and high-frequency cyclic operation scenarios is more prominent.
After the engine torque peaks and valleys are smoothed out, it always operates in a stable and comfortable condition, reducing high-intensity load impacts, effectively slowing down component wear, and thus significantly extending the overall service life of the engine and reducing subsequent maintenance costs.
Overcoming Hard Rock
More Powerful High-Altitude Power
The overall power output of the hybrid system is not affected by high-altitude environments, and the overall high-altitude power performance of the equipment is more powerful, with stronger adaptability to complex mountainous and high-altitude mining conditions. Facts have proved that the Cummins M15 hybrid-specific engine can handle hard limestone with calm power output, allowing Mr. Gao to handle tough operations with ease.
"Rock mines have high rock hardness and heavy loading tasks. The Cummins M15 hybrid-specific engine of this model has considerable power. We adopt a two-shift working mode, with people stopping but equipment not, and the equipment operates continuously for nearly 20 hours every day. The performance is stable and reliable, fully meeting the high-frequency operation requirements of Kunming mines."
The Cummins M15 hybrid-specific engine has delivered ultimate fuel efficiency, advanced hybrid technology, and powerful power to Mr. Gao.
