Pulleys accomplish 2 separate operations throughout the computer controlled additional benefit technologies listed elsewhere here.
Explanation:
If indeed the pulley would be connected to that same attachment point, these are named a corrected pendulum or perhaps a change in direction. Its job should be to reverse the trajectory of that same rope pull.
Unless the pulley would be connected to that same load, this same pulley seems to be a detachable as well as a mechanical additional benefit.
