Change constraint length with blueprint at runtime (crane cable)

Im trying to make a working crane and i need to be able to change its cable length for cargo lifting. How can i achieve that?

I’d define an end point (at the end of your crane where its moving up and down) and a start point at the highest point of the crane. Then you can spawn more elements at the top if needed, or destroy them, by checking the length of the Vector from Start to End Point.

Heres a tutorial that works similarly

I was hoping for simple “constraint length” in constraint component. So basically i need to extend length of constraint component by adding to its own length, right?
