How Make a Rope with Pulley?

Hello everyone. I am a newcomer here in the community, so, I mean that is a pleasure to be here participating with you.
I’m looking for effective ways to create a system of ropes with pulley, just like my image.

I’m not sure, but I believe the Box2D addon, can do this job. I’m using it for these tests, but I am having no success!

Could anyone help me with this?
