Wang Guodong, Secretary of the Party Committee and General Manager of Baotou Steel Group EBO Intelligent Manufacturing Technology Co., Ltd, Wang Yaolong, the open-pit mine manager of Huaneng Group North Weijiamao Coal and Electricity Co., Ltd., attended the event. Leaders of major mining enterprises, equipment companies, industry experts in the mining field, partners, and mainstream media gathered at the scene to witness this historic moment in China's large-scale mining power industry.

Through 18000 hours of practical testing

Equip our country's mining equipment with a 'Chinese heart'

Energy security is the 'greatest of nations'. The technology content and industrial barriers of large-scale mining power are extremely high, and for a long time, the market share of independent brands has been almost zero.

Faced with difficulties, Weichai and Guoneng Zhuneng Group, guided by national strategy, opened the prelude to the breakthrough of domestically produced large-scale mining power, and ultimately achieved the hard core result of independent and controllable 300 ton mining engines.

After a comprehensive and multidimensional special acceptance review, the expert group unanimously agrees that:

The 300 ton mining truck equipped with Weichai 12M55 has undergone 18000 hours of continuous practical testing under heavy load and high-intensity continuous operation conditions in mines. The engine's performance has reached the industry's advanced level, fully meeting the long-term high-intensity operation needs of large mining equipment. China's mining equipment finally has a "Chinese heart".

The core system is completely autonomous and controllable

Localization substitution accelerates industrial upgrading

As the benchmark for the first 300 ton mining truck powertrain in China, the core system of the 12M55 engine is completely autonomous and controllable: the exclusive ECU electronic control system can be optimized and customized for calibration at any time, and the ultra-high pressure common rail closed-loop control system can achieve precise control of the fuel system.

At present, Weichai mining truck power meets the demand for 100-400 ton mining trucks, which can perfectly adapt to various operation scenarios in large and ultra large open-pit mines, and can provide complete replacement solutions for all series of vehicle models according to customer needs.

Weichai has also established a dedicated service system for the entire life cycle of the mining industry, ensuring efficient delivery and equipment operation. It has laid out mining service bases and spare parts centers nearby, and helped mining enterprises achieve a win-win situation of safety, controllability, cost reduction, and efficiency improvement with the optimal three guarantee policy, sufficient spare parts reserves, complete training empowerment, flexible guarantee system, and full life cycle protection.

During the event, the attending guests visited the Guoneng Zhuneng mining area and observed representative models of high-end mining power products such as Weichai 16M33, 12M55, and 16M55 on site. Through the actual working conditions of two in use mining trucks, they intuitively felt the stable performance of the "Weichai Heart" power.

future

Weichai will continue to put customers at the center, take ensuring the safety of the industrial chain as its responsibility, adhere to high-level technological self-reliance and self-improvement, further deepen strategic cooperation with major mining enterprises, equipment enterprises, industry associations, and research institutions, and work together to promote the high-quality development of mining equipment in China.Editor/Cheng Liting
