How did these diggers get up there?

Excavators dismantle Chinese highrise from the top down.

They probably dismantled them and brought them up in the lift bit by bit.

I also don't see any sign of any health & safety officers.

Your average tower crane wouldn't have the capacity to lift these even if they were close to the jib.

Mobile crane with a superlift

Tried to zoom in on the pictures but I can't see clearly the model no. Look like Komatsu 210 . At a guess those exc are only 20t give or take a few t . Well within limits of a mobile

They're both only 13 tonne machines, easy lift for a large mobile crane.
They're putting incredible trust in the structure of a building they are compromising as they go. A worker was killed in Aus not too long ago when his machine went through a slab doing demo on a much lower building.

I don't think health & safety exists in China, I don't see any high viz vests.

Crazy isn't it? The reason they're demolishing it is because they were starting to lean. You wouldn't catch me up there driving a machine!

More likely some Russian\Chinese chopper if a helicopter. The Mil-26 can lift 20 metric tons and the machine is only 13 tonne.

Maybe a helicopter is more common than a mobile crane. Dunno.

Why not use the tried and tested wrecking ball. Faster, better, cheaper, safer and leave the machines on ground to tidy up after Mad chinese.

Nobody uses wrecking balls now and haven't for years. Most high rise buildings in Europe are demolished from ground level with high reach demolition excavators fitted with peckers, crusher jaws or shears (up to 90m reach but 30-60m more common). Top down is sometimes still done but with remote control Brokks (specialist radio control mini diggers with breakers)
