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.

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.

Simple. It is probably spoilt. You might want to get it fixed by a professional.
