Excavator 'house' Hows it work?

[chopped]

It is interesting its all stuff that we cant ''see''. Im assuming that this 'rotary manifold' would have to be centered in the disc. But then that leads to another question..Is there some sort of central middle bearing???
And then of cource I wonder are there rollers on the outer side?

With a crane when you set the house there are hook rollers that go underneath the ring gear. these travel with the house and the ring gear is tied to the track body. Pretty amazing when your talking a 150 ton lattice boom crane.
