The other day I noticed a mobile crain on the building site nearby where I work, not unusual. I thought they were putting up the steel frame of the building
You can see the guy checking things out in the cab
But they were still lifting concrete blocks
Next day it was lifting the rest of the crane in place
That's how they put a tower crane together
That,s not the biggest crane we have had, check out the link if you want to see it.
