How would you use a pulley system with one rope to pull at a single item at two points simultaneously?

The free ropes of two block and tackle pulley systems could be joined to pull an object in two places.

Or you could just hang a rope over two pulleys on a ceiling, tie both ends to the object to be lifted, and pull the rope in between the pulleys.

To use a pulley system with one rope to pull a single item at two points simultaneously, you have a few options:

1. Use two block and tackle pulley systems: In this setup, each pulley system consists of a fixed pulley and a movable pulley. Secure the object to be lifted to the two movable pulleys of each pulley system using separate ropes. Then, gather the free ropes of both systems and join them together, either by tying them securely or using a carabiner or a knot. By pulling on the joined ropes, you can lift the object at both points simultaneously.

2. Hang a single rope over two pulleys: Another option is to hang a rope over two pulleys that are mounted on a ceiling or any other sturdy structure. Attach one end of the rope to one side of the object to be lifted and the other end to the opposite side. Then, standing in the middle of the two pulleys, pull the middle section of the rope downwards. This will cause the object to be lifted from both points simultaneously.

Both of these methods allow you to distribute the force required to lift the object between two separate points, making it easier to pull or raise the load.
