Recently, our company's three fully hydraulic tunnel drilling machines have successfully passed the review of the national mining product safety mark and officially obtained the mining safety certificate (KA certification). This marks that our product has met the relevant regulations of the country, industry, and mining safety, and can be officially put into production, sales, and use.

The safety mark for mining products is an important certification mark established by the state to ensure the safety production of mines and ensure that mining products comply with relevant standards and regulations. Our products have passed this certification, which not only proves the excellent performance of our products in design, production, quality control, etc., but also reflects our high responsibility and commitment to mine safety production.

In the process of applying for mining safety certification, we strictly followed the relevant national and industry standards, carefully prepared and submitted relevant application materials and samples. After strict review and testing by the National Mining Product Safety Certification Center (CMAC), our product has successfully passed the testing and evaluation of various indicators and ultimately obtained a mining safety certificate.

We are well aware that mine safety production is related to the life and property safety of miners, as well as to the development of the national economy and social stability. Therefore, we will continue to uphold the concept of "safety first, quality first", continuously improve the quality and performance of our products, and provide users with safer, more reliable, and more efficient mining products.

At the same time, we also thank our users and partners for their trust and support. We will continue to work hard, innovate continuously, provide users with higher quality products and services, and make greater contributions to the safety of national mining production.
