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 Scraper Electric Control Device (ZGK127(H))” 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/HHZ011-2022, as well as the requirements of the mining product safety certification system.

The certification confirms that the product has passed a full conformity assessment process, including technical documentation review, type testing, factory inspection, and post-certification supervision, ensuring safe and reliable operation 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) mining equipment safety approval system

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

IECEx system for hazardous area electrical safety certification

However, the MA/CMAC certification is specifically designed for coal mine safety regulation in China, focusing on underground conveyor system operation safety, explosion protection compliance, and industrial control reliability in harsh mining environments.

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