In August 2025, a grand unveiling event for the new generation of XE750GKHEV mining hybrid excavator, equipped with a Cummins M15 hybrid engine specially developed for mining, was held in Yunnan. Following the global debut of XE650GKHEV in 2024, XCMG once again collaborated with Cummins to introduce an upgraded hybrid excavator solution, injecting new impetus into the green transformation of mining operations. Representatives from XCMG's excavator division, the Yunnan Mining Association, and relevant business leaders of Cummins China, along with over 130 partners from the entire value chain, participated in the event.
Cummins is committed to providing more low-carbon and environmentally friendly power solutions. In this event, XCMG showcased a matrix of hybrid and fuel-powered flagship products, including the XE650GK HEV and XE-750GK HEV equipped with Cummins 563-kilowatt M15 hybrid engine, as well as an 87-ton excavator.
During the practical drills simulating complex working conditions in a mining environment, the new generation of hybrid excavators equipped with Cummins M15 hybrid engine demonstrated outstanding performance. According to the actual measurement statistics of XCMG equipment, the energy consumption was reduced by more than 20% compared to the fuel-powered models.
As the core power unit of this hybrid product, the Cummins M15 hybrid engine combines high efficiency, energy conservation, intelligence and reliability.
With numerous innovative technologies, it provides a powerful "heart" for XCMG excavators.
Sturdy and reliable, easy to maintain.
The new independent cylinder liner, high-strength cylinder block and cylinder head structure give the equipment extraordinary heavy-load and anti-fatigue capabilities, ensuring its long-term stable operation. The front double-layer gear train adopts a fully sealed design, making it immune to high dust invasion.
All-fields Adaptation and profit-making Tool
After undergoing tests at 4800m altitude and -30°C extreme cold conditions, it is custom-developed based on Chinese working conditions and performance calibrated.
The engine communicates with the main pump and main valve in real time. During heavy loads, the engine makes torque compensation in advance to prevent the reduction of rotational speed, ensuring more stable performance.
Efficiency improvement, intelligently energy saving
Integrating advanced cylinder combustion optimization technology and intelligent thermal management system, the mass production thermal efficiency reaches as high as 48%, significantly enhancing fuel economy
Using the new turbocharger HE550WG to improve fuel economy and torque transient response
The new bowl-shaped piston design and 250Bar Cylinder burst pressure result in more thorough combustion and a more responsive dynamic performance.
Combined with the 2000Bar ultra-high pressure injection, it achieves full-range closed-loop high-precision fuel supply compensation, bringing users an ultimate fuel-saving experience.
In response to the specific needs of the mining market segment, Cummins will continue to deepen its efforts and is committed to providing customized low-carbon power solutions for the construction of green and intelligent mines. By leveraging innovative technologies and professional services, Cummins aims to create sustainable value for mining customers and jointly build a new ecol
