chains for a battering ram

Hello everyone

I made a battering ram and tried to give it physics. I tried Hinge joints for the chains

but the results are not really what I am looking for (the ram is bouncing up and down a lot) and if I try to increase the mass of the ram the chains break and everything is falling apart

im not really experienced with Unity and have no idea what other options I have.

Does anyone of you Guys got a better solution for stuff like this? or made something simmilar and can tell me how he got a relatively realistic result?
