This study focuses on the transformation of a traditional bridge crane in the concentrate warehouse of a gold-copper smelting enterprise into a 5G+ unmanned intelligent ore-blending crane. By integrating 5G technology with a standalone (SA) network architecture and developing automated control and warehouse management systems, the upgraded crane achieves intelligent operation and unmanned capabilities. Post-upgrade results show a 20 % increase in operational efficiency, а 70 % reduction in operational duration, and over 70 % decrease in safety incidents, signifi-cantly reducing costs, improving the working environment, and enhancing safety. This initiative provides a pioneering exploration of safe and efficient crane operations in heavy industries, offering a direction for the application of unmanned cranes in non-ferrous smelting enterprises and contributing to safer and more sustainable production practices.
