Crossing construction over existing infrastructure may cause substantial economic losses and introduce serious safety risks. Therefore, improving the safety and efficiency of live-line crossing construction is of practical importance. This paper proposes a cable-net deployment robot system that automates the installation of protective barriers on energized transmission lines. The system integrates a mobile robot with multiple cooperative deployment units and incorporates mechanisms for stable locomotion, anti-fall self-locking, and axial locking. Experiments under simulated operating conditions demonstrated that the system maintained structural stability under a maximum load of 5750 N, withstood a 22 kg equivalent impact mass at a 5 m drop height, climbed a 15° slope without slippage of the conical magnetic-adsorption wheels, and exhibited a traction force of approximately 41 N during steady motion, with fluctuations of 15-65 N during obstacle traversal. Moreover, a clear, consistent fluctuation pattern between traction and wheel angular velocity enabled adaptive locomotion across varying conditions. These results verify the feasibility and reliability of the proposed system and provide a practical robotic solution for improving the safety and efficiency of live-line barrier installation.
