A type of
stagehand. Riggers are responsible for
flying (hanging) items from the
ceiling of a
building and doing it safely. They are trained in load handling and working with the rated strength of the building they are working in.
When you go to a rock concert and see all those lighting trusses hanging from the ceiling by chain motors, how do you think those motors got up there? Riggers put them there.
Riggers are generally good guys, as putting themselves in situations that could instantly cause your death and is avoided by most people gives them a certain zen sense.
They are also kinda piratey, but in a nice way. I guess it has to do with hanging from ropes suspended way-too-fucking-high in the air.
