I'm a journeyman crane operator and when I looked at that vid two things made no sense at all.. a) where did the ball come from? The crane in the picture was not moving so for the ball to swing like that it had to have been hung up on something somehow.. yet if that was the case how come there was absolutely no shock load at all on the crane? If that had happened in real life with a giant ball like that (many times too big for the crane pictured) it would have flipped the crane over. The crane didn't even rock. b) I've never worked demolition before... one of the most dangerous and technically demanding crane tasks, but I know they would not use a modern rubber tired, telescoping boom crane for that. Demolition work is for crawler cranes.. and not the new ones with the high tensile steel booms, but for the old cranes with heavy booms |
