Based on the original JV Series vertical lifeline system, our company has implemented technical improvements and developed a derivative model by incorporating engineering experience and customer feedback. We are pleased to officially introduce the JC Series vertical lifeline device. To help customers clearly understand the differences and improvements between the two models, we hereby provide the following statement: The JC Series is a derivative model of the JV Series. The main design changes are as follows: The JC Series vertical lifeline device has obtained certification from CCQS. Certification Standard: This standard is a mandatory compliance requirement for vertical lifeline systems in the European Union market. The JC Series products have successfully completed all required type testing and performance verification in accordance with this standard. The certification is valid and authentic. The JC Series is not intended as a replacement, withdrawal, or recall of the JV Series. It is an alternative solution developed for specific application scenarios and user requirements. Although the location of the energy absorption structure has been modified, the JC Series achieves the same level of impact force control and fall arrest performance as the JV Series through the textile energy absorber integrated into the slider/fall arrester assembly. This statement is intended solely to explain the design differences and compliance status between the JC Series and JV Series products. For detailed installation, operation, inspection, and maintenance requirements of the JC Series, please refer to the accompanying product manual and the EN 353-1 certification documents. If you require copies of the JC Series certificates, test reports, or additional technical information, please contact our technical or sales team.1. Model Relationship and Design Changes
