Summary:
As a critical piece of construction equipment in tunneling, mining, and underground engineering projects, the safety certification of wet-spray robotic platforms is a core component for ensuring equipment quality, construction safety, and market access. China has established a multi-tiered safety certification system that encompasses national mandatory standards, industry standards, group standards, and international certifications, providing clear technical guidelines for the design, manufacturing, inspection, and operation of wet-spray robotic platforms.
I. Domestic Core Standard Certification Requirements
Wet-mix shotcrete boom trucks in the domestic market must meet the following key standard requirements, which form the basis for equipment safety certification.
1. Mechanical Industry Standard “Concrete Wet-Spraying Platform for Rock Roadways”
This standard is one of the most important industry product standards for wet-mix shotcrete rigs. It specifies the rig’s type, basic parameters, technical requirements, test methods, and inspection rules. The standard applies to the manufacture of wet-mix shotcrete rigs used in rock tunnels in metallic and non-metallic mines, coal mines, railway and highway construction, and underground engineering projects. Equipment manufacturers must ensure that their products fully comply with the requirements of this standard during design, production, and factory inspection; compliance is a prerequisite for obtaining industry certification.
2. Group Standard “Construction Machinery and Equipment: Concrete Spraying Bogie”
This standard is issued by the China Construction Machinery Industry Association and focuses on concrete pump wet-spray trolleys that are either built on self-propelled wheeled specialized chassis or modified from standardized Class II automotive chassis. It provides supplementary provisions addressing the specific characteristics of such mobile equipment, including chassis compatibility and driving safety. Manufacturers of equipment that comply with this standard may, in accordance with the prescribed procedures, apply for and obtain the corresponding group-standard conformity certification.
3. Mechanical Safety Certification
China’s machinery safety certification adopts internationally recognized certification schemes and conducts rigorous assessments of product safety performance. Enterprises applying for certification must meet the following basic requirements:
Possess a valid business license.
The product complies with the requirements of the applicable mandatory national standards or industry standards.
Product quality is stable and capable of mass production.
The enterprise has established a standardized quality management system.
The certification process comprises application submission, document review, product type approval, audit of the enterprise’s quality management system, and testing of product safety performance, among other steps. Upon successful completion, a certification certificate is issued with a validity period of four years.
II. International Certification and Requirements for Special Application Scenarios
For wet-spray trolleys intended for export or specific application requirements, compliance with the relevant international or industry-specific certifications is also required.
1.CE Certification
Wet-spray trolley exported to the EU market, CE Certification is a mandatory requirement. It demonstrates that the product complies with the relevant EU safety, health, and environmental protection standards. The certification process primarily includes project application, document preparation, product testing, report compilation, submission for review, and certificate issuance. Among these steps, the preparation of technical documentation—such as drawings, electrical schematics, and user manuals—is of paramount importance.
2. Mining Explosion-Proof Certification
When wet-spray trolleys are used in coal mines and other environments with explosive hazards, the equipment must comply with the specific requirements of the mining explosion-proof standards and obtain the corresponding mining product safety certification. This necessitates that all electrical components and mechanical structures of the equipment be designed to be explosion-proof, thereby eliminating any potential ignition sources.
III. Certification Process and Ongoing Compliance Management
Safety certification for wet-spray trolleys is a systematic undertaking that places particular emphasis on post-certification oversight.
1. Overview of the Certification Process
Generally, the certification process begins with a company submitting an application to a qualified certification body. Subsequently, the company must prepare comprehensive technical documentation, and the product is sent to a nationally accredited laboratory for safety performance testing. The certification body also conducts an audit of the company’s quality management system. Once all these steps have been successfully completed, the certification center approves and issues the certificate.
2. Post-Certification Supervision and Maintenance
Obtaining certification is not a one-time, set-it-and-forget-it achievement. During the certificate’s validity period, the certification body will conduct regular surveillance audits of the manufacturer’s quality management system and inspections of product safety performance to ensure that certified products continue to comply with the certification requirements. Enterprises must properly manage their certification certificates and marks, use them only on certified products, and remain subject to oversight by the certification body.
Summary
The safety certification requirements for wet-spray boom trucks constitute a multi-tiered, comprehensive compliance system. Equipment manufacturers and users must accurately identify and meet the applicable standards and certification requirements based on the target market—whether domestic or international—and the specific application scenario, such as general construction projects or specialized environments like coal mines. By adhering to rigorous certification procedures and maintaining ongoing compliance management, not only can construction safety and equipment reliability be effectively ensured, but the product’s ability to legally enter the target market and earn user trust is also critically dependent.
