Pawn doesn't swing

I have a simpla crane Pawn with some constraints.
When i move the arm left and right it doesnt swing, but when it hit something it reacts right.

I nearly searched for an hour for the right setting. What do i am doing wrong here?

Thanks for any help.

Make sure the physics start awake.

I did, that is not the problem.
I made this work now. Instead of using “Player Start” in the scene, i place it manually in the scene and used “Auto Posses Player -> Player 0”.

But i don’t understand what the difference is.

Here i made a video about that isue:

I still don’t understand why the physics are different from “Player Start” to manually place the Pawn into the scene with “Auto Posses Player -> Player 0”.
