The Catenary Intelligent Comprehensive Inspection Device is a self-propelled intelligent detection unit that integrates laser measurement, 3D recognition, and high-definition imaging technologies. It can precisely locate and perform high-definition imaging of catenary supporting devices, auxiliary suspensions, contact suspensions, dropper seats, and pole number areas, while also providing static detection of catenary geometric parameters. It is used for daily inspection and maintenance of catenary suspension facilities on electrified railways.
