T3F Hanging rail robot is an intelligent inspection solution designed specifically for the wind power industry. With the smallest size in the industry, the robot is able to carry out inspection tasks in a narrow space, realizing a closed-loop system of all-weather data collection, information transmission, intelligent analysis and early warning for inspection, operation and maintenance control, which not only improves the operation and maintenance efficiency of wind farms and reduces manpower costs, but also significantly improves the safety and reliability of wind farms.
