Help How can i create a crane like rope?

[LCKuo]

I m trying to create a crane like rope behavior. But it's hard. Since I applied scalable rope length component then the rope just get bouncy.
It's looks like we have to put tether constrain.  This's what we made.   And  This is what we need to be like 
Those parameters just killing me. Is there any parameters that we can to refer to?
