if you use a double fixed pully, it could make the rope or wire haver that much more preasure
The main advantage of using a pulley system compared to just running the rope over a branch is that the pulley reduces the amount of friction and effort needed to lift objects. By passing the rope upward and through a single pulley, the load is distributed more evenly, making it easier to pull downward to lift the object.
Reduces friction and makes it easier to lift the object by changing the direction of force.

Passing the rope upward and through a single pulley creates a mechanical advantage, making it easier to lift the object with less effort. The pulley reduces the amount of force needed to lift the object by distributing the weight across multiple strands of the rope. This configuration also allows for a smoother and more controlled lifting motion compared to just pulling the rope directly over a branch.
Passing a rope upward and through a single pulley increases the mechanical advantage, making it easier to lift heavy objects by applying less force. This setup also allows for better control and direction of the lifted object compared to just putting the rope over a tree branch.

I think what you want is the "mechanical advantage". It's 2 .
You have to have the right size pulley for the weight of the object you want to move and a secure place to attach it. Then, once it's all hooked up, you'll need to generate the force to pull on the rope or cable that will then move your object. If it is more than you can produce with your body, you can attach an engine to it and let it do the work.

Reduces friction
Although a single pulley doesn't offer a mechanical advantage as does the compound pulley, sometimes it can be helpful to change the angle. For example, when lifting an object, it may not be desirable or possible to stand directly above or below it. A single pulley allows one to stand to the side and pull. It also eliminates the friction associated with pulling a rope over a sharp edge, which would be the case if pulling at an angle over the edge of, say, a rooftop.
Reduces friction
Simple. It is probably spoilt. You might want to get it fixed by a professional.
To make a horizontal pulley system, you will need a fixed support structure, a pulley wheel, and a rope or cable. Attach the pulley wheel to the support structure and thread the rope through the wheel. Secure one end of the rope to the object you want to move and pull on the other end to create a mechanical advantage for lifting or moving the object horizontally.
The rope pulled over the branch is hampered by the rope's friction over the branch. The same rope pulled over a pulley is not affected by friction as the pulley wheel will turn as the rope is pulled.
