Recently, the "Qiyuan&Tongli - Rio Tinto's first 91 ton battery swapping wide body mining truck launch ceremony" was grandly held at Tongli Heavy Industry's Xipo base. The 91 ton DTE145 wide body mining truck released this time is another milestone achievement of close cooperation between Tongli Heavy Industry and Qiyuan Core Power, which will provide mining giant Rio Tinto with safer, more efficient, and environmentally friendly engineering transportation solutions.
As a global mining leader that integrates mineral resource exploration, mining, and processing, Rio Tinto Group regards low-carbon transformation as its strategic core, planning to achieve a 50% reduction in operational emissions by 2030 and a net zero emissions reduction in operational operations by 2050. The pilot project of pure electric to electric mining cards launched by Rio Tinto in its mining operations is an important step towards achieving carbon reduction targets.
In recent years, as new quality productive forces driven by technological progress and industrial innovation, new energy and intelligence have become new highlands for upgrading and improving the transportation industry chain. Tongli Heavy Industry is also continuously promoting the research and application of new energy and intelligent technologies, contributing to the sustainable development of the mining transportation industry.
In fact, as early as 2015, Tongli Heavy Industry had already embarked on the path of automation and green development, successfully restructuring the industry's first lithium titanate battery pure electric wide body vehicle. Up to now, Tongli Heavy Industry has established a safe, green, and comprehensive intelligent new energy product system through product combinations such as pure electricity, battery swapping, hybrid, hydrogen fuel, and line control in the field of new energy products.
In 2019, Tongli Heavy Industry and Qiyuan Xin Power cooperated, based on Tongli Heavy Industry's comprehensive accumulation and industry advantages in product technology, supply chain system, manufacturing process, and market services in the mining engineering transportation industry. With the help of Qiyuan's leading advanced technology in the field of "green electric transportation" and high-quality energy service capabilities, both parties leveraged their respective advantages to develop and solve pure electric products, forming a strong alliance. The cooperation results have gone from the initial 70 ton product to the 91 ton DTE145 wide body mining truck released this time. The product has been applied to multiple large open-pit coal mines in China, and this time DTE145 will be applied in copper mines in Mongolia, opening a new chapter of cooperation between the two sides to serve overseas mining enterprises.
DTE145 is a new generation of non road transportation equipment jointly developed by Tongli Heavy Industry and Qiyuan Xin Power, which integrates high reliability, long service life, high efficiency, low emissions, and high safety features. It can effectively assist the global mining industry in reducing carbon emissions.
Rigid welded frame+all oil and gas suspension+A-frame guidance, large capacity battery+permanent magnet synchronous drive system+3 gearbox, MTBF significantly increased to 800 hours. Adopting forward development of rigid frame and CAE simulation multi wheel optimization, the safety factor in key areas exceeds 3 times. Key components of mining vehicle chassis are used, with a design life of ≥ 10 years. Pure electric drive, with a speed of ≥ 15 kilometers per hour on an 8% slope and a maximum speed of kilometers per hour, meeting the operating speed standards for mining vehicles. Equipped with a dual cylinder lifting system and short unloading time. The Qiyuanxin Power Mining Card 800 battery system can meet the requirements of electric mining cards with large load capacity, complex transportation scenarios, high endurance requirements, and large environmental temperature differences. If green electricity is used, nearly zero emissions can be achieved, and the annual carbon reduction per vehicle can reach over 250 tons. Adopting FOPS&ROPS certified cab, the application of fully hydraulic steering+emergency steering system, electric braking and hydraulic braking are organically combined to ensure high safety of vehicle operation.
In the future, Tongli Heavy Industry will continue to focus on the goal of "safe, efficient, green, and intelligent" mining construction, and steadfastly promote research and development innovation. With an open and inclusive attitude and the ambition to continue leading the industry, we will provide customers with cost-effective, safe, and reliable green smart mining transportation solutions, and continuously enhance the product value of our customers. Tongli Heavy Industry firmly believes that with the continuous advancement of technology and the expansion of application scenarios, new energy and unmanned driving products will continue to lead the mining transportation industry towards a better future.
