BD8DIN If you're in a hurry, there is actually another possible method: As everyone knows, mechanical waves are also waves and will naturally move. Perhaps by vibrating the rope in a certain way, you could push the hook in the middle forward... Since you don't need to buy or make anything, you can simply try it out to see if it works.
Disclaimer: The above information applies only to spherical nylon ropes, buildings, oscillators, and hooks in a vacuum environment.
Alternatively, you could simply use a long pole to lift the rope on this side and see if you can slide it over.
