[0051] In the above steps, since the width of the lifting beam of the hook itself is large enough, the wire rope of the hook exceeds the width of the second movable cable transport frame 84, ensuring that the hook does not interfere with the telescopic cable transport frame 8 within the normal lifting height range.
[0052] Step 3: Driven by the telescopic device 85, the first movable cable transport frame 83 and the second movable cable transport frame 84 move toward the head of the arm frame 7 through the track, and adjust the length of the telescopic cable transport frame 8 to an appropriate position according to the cable installation requirements;
