Excavator - Rigged

I Like to move it move it ... I Like to move it move it...

Yihaaaa...first rig ever ist nearly completed^^
Tubes will be skined during next days, but its enough for today.

After 10 hours of work, I cant hear things like bones, parent, attachments, constrains, wire parameters ,controls, dummys, graph/parameter editor,  etc. for the next few hours, but im still confident with it.

No I´m looking forward to make it spinning around being the actual lord of destruction haha.
