Last week, we posted a couple videos of a 580 ton bridge girder erection machine with extendable arms that allow a girder to be dropped into place from above. The view of those videos were a little far away, so it was hard to get good details on how it worked and what exactly was going on, but now a third video has been uploaded to Youtube by Extreme Mega Machines that could help fill in some of the blanks.
In the video blow you can see how the connections are made, the mechanism that drops the girder into place, how the wheels are lifted, and several other interesting views of a girder set. After posting the last video, several people pointed out that the didn’t think the workers standing on the columns were properly harnessed and these views seem to support that thought, as well. There is certainly some opportunity for improvement in the safety department, but this is still an incredible machine and a great concept.
On Tuesday morning, February 23, the Syracuse Fire Department responded to a call about a collapsed crane on a construction site near the university. Thankfully, no injuries were reported.
