This certificate is issued under the China Mining Product Safety Mark Certification System, administered by the National Center for Safety Mark Certification of Mining Products (AQB).

It certifies that the product “Mining Belt Conveyor Alignment Electric Control Device (ZJK127(A))” manufactured by Huaibei Hezhong Mechanical Equipment Co., Ltd. complies with relevant Chinese mining safety standards, including GB/T 3836.1-2021, GB/T 3836.4-2021, MT 209-1990, and enterprise standard Q/HHZ031-2024, as well as the requirements of the mining product safety certification system.

The certification confirms that the product has successfully passed a full conformity assessment process, including technical documentation review, type testing, factory inspection, and post-certification supervision, ensuring stable and safe performance in underground coal mine environments.

In terms of international alignment, this certification is functionally comparable to global mining and hazardous area safety systems such as:

MSHA (Mine Safety and Health Administration, USA) approval for mining equipment safety compliance

ATEX Directive (EU 2014/34/EU) for equipment intended for explosive atmospheres

IECEx system for hazardous area electrical equipment safety certification

However, the MA/CMAC mining safety certification is specifically designed for coal mine operational safety in China, with a focus on underground belt conveyor system reliability, explosion protection compliance, and safe electrical control performance in hazardous environments.

Products with this certification are officially approved for use in coal mine operations in China, ensuring compliance with national mining safety regulations.
