In recent years, electric earthmoving machinery has become a new trend in the development of the industry. China's electric earthmoving machinery has made significant progress in technological innovation, environmental protection and energy conservation, market share, and international influence, and the innovative achievements have been applied around the world. However, the industry still lacks safety standards related to electric earthmoving machinery.
The "Safety Requirements for Electric Earthmoving Machinery" systematically proposes safety requirements and specifies implementation standards for B-level or above electric earthmoving machinery for the first time. It clarifies the requirements for general safety, dust, water, fire, battery system safety, motor and electrical control safety, charging safety, and battery swapping safety of electric earthmoving machinery, and correspondingly specifies the testing methods for electric earthmoving machinery.
This standard is conducive to regulating and ensuring the safe use of electric earthmoving machinery, reducing accidents, minimizing casualties and equipment damage, improving the reputation of enterprises, maintaining social stability, and protecting the environment and ecology. At the same time, it can also promote the improvement of the quality of electric earthmoving machinery products and guide the industry to design products that meet national standards with unified standards.
General Requirements for the Battery Replacement System of Pure Electric Hydraulic Excavators in Earth moving Machinery
In electric earthmoving machinery, electric excavators are widely used in scenarios such as river cleaning, disaster relief, mining, and dam construction. However, due to remote working conditions and slow track movement, the inconvenience of energy replenishment has become a bottleneck for the commercialization of electric excavators. Therefore, it is urgent to research and apply battery swapping technology for electric excavators.
The release of the "General Requirements for the Battery Replacement System of Earth moving Machinery Pure Electric Hydraulic Excavators" can solve the current situation of no standard for the battery replacement system of pure electric hydraulic excavators, provide standardized and scientific standards and theoretical basis for the requirements, testing methods, and inspection rules of the battery replacement system of electric excavators, promote the development of battery replacement electric excavators, and guide the industry to design high-level battery replacement excavator products.
This standard specifies for the first time the technical requirements and test methods for the number of battery changes required for electric excavators, safety requirements for the battery change process, battery change environment, and battery change duration.
In 2014, Liugong was the first in the industry to embark on the path of electrification research, and has now gone through more than 10 years of history. As a leading enterprise in the electrification of construction machinery, Liugong has always taken it as its responsibility to promote the development of the industry. Since the establishment of the Electric Earthmoving Machinery Sub Technical Committee of the National Earthmoving Machinery Standardization Technical Committee, Liugong has been committed to formulating high-level national and industry standards for the country, contributing its own wisdom, and promoting the development of upstream and downstream enterprises. The release of national green standards this time is not only a certification of LiuGong's strength in electrification, but also a powerful demonstration of LiuGong's leadership in industrial upgrading and injection of green energy.
In the future, LiuGong will continue to play the platform role of the Electric Earthmoving Machinery Technical Committee, under the leadership of the National Earthmoving Machinery Standardization Technical Committee, collaborate with industry peers to tackle challenges, continuously output more high-quality standards, and contribute LiuGong's strength to improving the technical level and international influence of China's electric earthmoving machinery products.
