video

Portland Oregon. No accident to report. just a link to a youtube video of a tower crane being erected. I'm often asked the question of how they are erected or climbed. Here is a good time lapse of it being done. If it wasn't time lapse you could use this video instead of taking Ambien.

November 10th, 1978


Charolette North Carolina

A 390 to 630 Liebherr tower crane dropped a "steel rod" (I hear rebar) from a beam. It went through a school bus. Fortunately no kids were in the bus at the time and the steel rod missed the bus driver. Often we are asked to hoist over the street. You'll see jobs with laydown yards accross the street from the jobsite because the site itself is being 100 percent used. The practice of hoisting over the public has to be stopped. In most cases this would have nothing to do with the crane itself but rather the rigging and those practices.
