Recently, the results of the TOP50 annual product selection for construction machinery, which has attracted much attention in the industry, were officially announced. XCMG Mining Machinery's XE650GK HEV large tonnage mining hybrid excavator stood out and won the 'New Energy Product Innovation Gold Award', solidifying the leading position of domestic mining equipment in green transformation with its hardcore technology strength and once again refreshing the industry's low-carbon equipment technology height.
Against the backdrop of the comprehensive implementation of the dual carbon strategy and strict control of energy consumption and emissions in mining, the high fuel consumption, carbon emissions amplification, and high operating costs of traditional large tonnage fuel powered excavators have become the core pain points restricting the high-quality development of mining enterprises. Foreign brand hybrid products are priced high, core technologies are blocked, and post maintenance is cumbersome. Domestic mining enterprises have long lacked cost-effective and fully autonomous heavy-duty hybrid solutions. XCMG, which has been deeply involved in mining machinery for more than 30 years, relies on a global collaborative research and development platform, focuses on continuous efforts to tackle heavy mining conditions, and has completed independent research and development of the entire hybrid power system chain after three years. It has created the flagship hybrid excavator XE650GK HEV, which is suitable for hard rock mining and earthwork stripping.
On the technical level, this model has broken through three major industry bottleneck technologies: dynamic load dual electric rotary energy recovery, multi physics field hybrid power matching, and engine waste heat recovery. Innovative parallel hybrid power architecture, with a rotary braking energy recovery rate exceeding 50%, significantly reducing energy loss in the hydraulic system; Equipped with a new generation intelligent collaborative electronic control system, it matches the engine, motor, and hydraulic output in milliseconds, ensuring no attenuation during heavy load excavation and reducing fuel consumption during light load operations. Actual test data shows that compared to pure fuel excavators of the same tonnage, the overall energy efficiency of the whole machine is improved by more than 15%. A single equipment can save fuel of 200000 to 300000 yuan per year, and carbon emissions are significantly reduced, perfectly balancing production efficiency and environmental protection needs.
In response to the harsh environment of high dust, strong impact load, and 24-hour uninterrupted operation in mines, XCMG has specially strengthened the overall structure of the machine. The key load-bearing structure adopts remelting welding annealing process, thickens the wear-resistant bucket and heavy-duty track chassis, resists impact and wear, and increases the average trouble free working time of the equipment by 20%; The driver's cabin is equipped with multi-stage shock absorbers, silent air conditioning, and ergonomic suspension seats, greatly reducing fatigue during long-term operations. The digital central control screen displays real-time energy consumption, power, and fault warning data, making operation convenient and intuitive.
It is worth mentioning that the entire machine has achieved 100% localization of core hydraulic, hybrid three electric, and power components, completely eliminating dependence on overseas components. The modular universal design allows 95% of components to be interconnected with XCMG's existing mining operations, and over a thousand service outlets across the country can quickly complete maintenance and parts replacement. Compared to imported hybrid equipment, the comprehensive operation and maintenance costs have been reduced by nearly 50%. At present, this model has been deployed in large open-pit mines such as Yungui, Inner Mongolia, and Shanxi in batches, with more than 40 equipment operating simultaneously, responsible for high load processes such as granite crushing, ore loading, and earthwork stripping.
The heads of multiple mining companies have stated that the long-term use of imported excavators, high oil costs, and maintenance expenses have compressed profits. After replacing with XCMG hybrid models, production capacity has not decreased, operating costs have significantly decreased, and the pressure of low-carbon transformation has been simultaneously alleviated. Relying on hybrid products such as XE650GK HEV, XCMG has now built a complete hybrid mining matrix ranging from 65 tons to 87 tons, covering the entire scene of small and medium-sized sand and gravel mines and large metal mines.
Winning the top industry award this time is a dual recognition of XCMG's green innovation by the market and industry authorities. In the future, XCMG excavators will continue to deeply cultivate the diversified new energy track of hybrid, pure electric, and hydrogen fuel, and provide a complete set of green and intelligent mining equipment solutions to assist the green and low-carbon transformation of domestic mining industry, and promote the continuous ascent of domestic high-end excavation machinery to the global industrial peak.
