Development of a UAV Towing Hook

This paper presents the development concept of a UAV towing hook designed for use in combination with the "UAV + Little Flyer" device. Compared with conventional towing hooks, the proposed design incorporates a guidance unit that facilitates easier suspension and alignment during operation. In addition, the hook is equipped with a safety mechanism to prevent accidental detachment during maintenance tasks. The device has already been widely applied in transmission line maintenance operations, effectively enhancing both safety and operational efficiency.
