Very nice, and something you don't see everyday.
Here in Norway we don't have so many skyscrapers to excavate on.
But when we build powerlines its not unusual to fly an excavater.
Problem is the Bell 214 doesn't lift the exc in one piece....
I spent a summer in a Kobelco 903 working on the powerlines, wasn't nessecery for me to move by air that summer...though.
But you demont the stick, fly it.
Demount the boom, fly it.
Demount all but 4 bolts on the mainbearing, connect to the chopper, take out the last bolts and fly the mainpart.
At last you fly the undercarrige.
Then you fly yourself in a smaller copter to the mounting site.
Chopper lifts the mainpart and puts it on the undercarrige. Those pilots are extremely skilled. Fit that mainpart to the undercarrige with a helicopter!
Boom and stick mounted last with the chopper.
On shorter moves you use your tracks. They fly your tools anyway.
Normaly u have a compressor, barrack, toolscontainer, timber, iron and fueltank.
Everything moved with the chopper.
You work in two or tree teams together. One on each powerpole/post. Move when u have finished a post.
Got a lot of passenger time in a chopper that sumer.
