Vibrating on translate or rotate(hinge joint)

Hi,

I am trying to move trolly of the crane or lift the arm of the crane up and dwn.On stop of the movement it is swinging by hinge joint by physic engine.
But while moving the trolly the objects hanging to the crane are vibrating, which I want to avoid,

Please find the attachment.

check the mass and general physics settings.

Also ensure to try them on unity 3, cause the upgraded physx has a much stronger linear equation solver which is a crucial part of your setup

You might get a better result in this case with a configurable joint. Give the joint free rotation, and set the X/Y/Z motion to Limited in the axis that points upward from the vehicle to the crane and Locked in the other two axes. Then, give the joint a very small linear limit value (say about 0.1 or less). This should give the joint a bit of slack to cope as the crane gets dragged.
