On April 21, a large-scale continuous belt conveyor, independently developed by CRCHI, was successfully installed and commissioned in Changsha and is set to be shipped to Spain for delivery. This marks the first time a domestically-produced continuous belt conveyor has entered the Spanish market.

It was learned that this continuous belt conveyor, with a total length of 4,500 meters, will be used in the expansion project of Line 8 of the Barcelona Metro in Spain. Through customized development, the R&D team has integrated features such as continuous slag removal, intelligent control, environmental noise reduction, and safety protection, with over 95% of the key components sourced domestically.
