How'd they get those excavators up there?

In pieces?

That is pretty neat.

Kinda reminds me of this scenario.

Will any helicopter lift a big excavator like that in one piece?

I find it interesting they are sitting on top of the building they are tearing down. How do you drop to the next floor without going down to the bottom?

I’d say they picked them up with their hands and set them there then they zoomed in so you don’t realize the building is only 2 foot tall. That or it’s a video game. I’m fairly certain it’s not real.

They climb. FF to about mid video.

That’s a steel structure specifically designed for that stunt. You can’t just go climbing buildings with excavators.

Simple. They use a sky hook!

According to this article High Anxiety: Rooftop Excavators Tear Down from Up Top that's a fairly common way to tear them down in China. A small comment at the end of the article states that they use a bigger crane to get the machine up there.

None the less, Leibherr makes some dandy machines. I suspect they were lifted up there with a heavy lift chopper. Probably the house and then the sticks.

Unfair. We have to do it from the ground.

Suspended belief - extreme chimney demolition in Austria

Contractor Felbermayr recently brought down a 100-year-old brick-built chimney in Wels, Austria, using a mini excavator suspended from an all terrain crane

Razing the roof

Cranes are still needed on demolition jobsites, though not necessarily for the applications that they were used in the past. ACT reports

I think that I read about that in Sunday School many years ago... wasn't that excavator named "David"? I'm quite sure that was his sling at the end of the boom.

Yes. A Sikorsky sky crane could do it

MIL MI26, can carry 10-long ton on a long line.

M-26–the world's largest heavy-lift helicopter–which is capable of transporting up to 44,000 pounds.
komatsu PC 300 LC weight 70327.5 lbs

its possible i guess to lifted in pieces and assemble on the roof top but you need a lift to assemble the boom so i am not sure.

It holds the worlds record for lift by a helicopter
In 1982, It lifted 125,000 pounds to 6500 ft in the air!

My gut reaction is in full agreement with you.

As I saw it....there were TWO of them....why would they need two when one alone could reach probably 75% across entire building without moving? (this presumes it is on the FAR side.....if it's in middle, it can probably reach all sides, so why crowd with two of them?)

Also, when they build buildings, my guess is they build them with the thought that the floors and ceilings are safe for purpose..... not safe for having not one, but TWO fairly heavy duty machines rolling around the roof?

Yeah, call me skeptical.

As I said in the post with my link above, they use a large crane to lift them up. Apparently it's a common practice in China, where they don't bother with trivial things like a solid base before building. They might be tearing down something today which they built last year.
