Shenli Rigging Passes First Annual CRCC Surveillance Audit After Relocating to New Factory

From July 25 to 26, an expert team from the China Railway Inspection and Certification Center (CRCC) visited Shandong Shenli Rigging Co., Ltd. to conduct an on-site annual surveillance audit following the company's transition to updated standards and the relocation of production to a new facility. After a comprehensive assessment, Shenli Rigging successfully passed the audit, and its certification remains valid.

CRCC is a leading third-party certification body in China’s railway product sector. This surveillance audit covered three core areas: a comprehensive assessment of the factory's quality assurance capabilities, on-site product sampling and testing, and a review of compliance regarding the use of certification marks. Guided by the latest railway product certification rules and the TB/T 2075-2024 standard for electrified railway catenary components, the expert team conducted a systematic and rigorous review covering technical document management, production site control, supply chain management, finished product consistency, equipment calibration, product testing and verification, and quality traceability systems.

During the audit, the expert team visited the new factory's production lines to verify process execution, controls on key raw materials, and the inspection process for finished products prior to shipment; they also selected certified products on-site for performance testing. Simultaneously, they conducted a detailed review of all documentation—including quality system files, supplier management records, non-conforming product disposal logs, and records regarding the use of certification marks—evaluating the company's standardized control capabilities for its intelligent production lines and its end-to-end quality traceability system.

The audit identified one minor non-conformity, for which the company has already formulated a closed-loop corrective action plan. Based on the comprehensive review, the expert team concluded that the factory’s overall quality assurance capability is stable and reliable, effectively ensuring the consistent quality and conformity of certified products; the control system operates effectively; sample test results met railway industry standards; and the company’s procedures for using certification marks are compliant with regulations. The expert team unanimously agreed to approve the annual surveillance audit.

This audit marked the first CRCC surveillance review since the company transitioned to the new standards and commenced operations at its new production base. Successfully passing this audit demonstrates the authoritative body's recognition of the company's end-to-end quality control and intelligent manufacturing capabilities. It also validates Shenli Rigging’s ability to ensure stable and reliable delivery of rigging components for electrified railway catenary systems, further solidifying the company's compliance credentials and core competitiveness in the railway market. Moving forward, Shandong Shenli Rigging will continue to adhere to CRCC railway standards as its fundamental guideline. The company will further optimize intelligent production line processes, upgrade its end-to-end quality control system, and strictly ensure product consistency, safety, and reliability. By providing high-quality products for electrified railways, it aims to actively support the construction of major national projects—such as high-speed railways and intercity rail transit—thereby contributing to the high-quality development of my country's rail transit industry.
