When will another U.S. or Canadian construction site suffer from another 'tower crane' collapse?

This settled collapse is not a "tower crane." Just because it is one of the biggest cranes doesn't make it a tower crane. A tower crane works on towers. They are at the top of towers or on top of something next to a tower. Tower cranes are worrying people lately because non workers walk under them everyday, but they don't collapse often. Regular large cranes, on the other hand, collapse all the time. I supervise (as a surveyor) the loading and unloading of bulk product at the port of New Orleans. We have a crane collapse (usually the boom on the older kind that we are gradually replacing) every few months here alone (with injury and occasional fatalities). Now multiply that with every other port in the U.S. / Canada and this happens every month. This should have been settled only if a "TOWER CRANE" collapsed.

Good points made...wasn't that aware of the differences...although common sense does dictate.

Were the accidents referred to in the question involving tower cranes, or 'regular large cranes' as Epicur referred to.

Needs to have settlements issues cleared pretty soon

BTW Epicur...only about 70 miles from ya here in Gulfport

@Bayoubear.
Epicur's comment was made 5weeks ago when this question was settled falsely.
The question was re-opened due to epicurs valid arguement which I entirely agree with.
This question refers to "Tower Cranes" which are often used for the construction of hi-rise buildings.

Ok. Sorry for the fast post.
This is probably NOT a "Tower Crane". It was being used to construct a part of a refinery, AND althought it was a giant crane (took two months to construct on site), it WAS constructed "on the ground".

yeah, they are calling it the "largest mobile crane in the nation", so that would probably not be a tower crane. Also, from the video, it doesn't appear to be a tower crane configuration.

They brought it in for some maintanence.

So perhaps another question should be formed related to any construction and/or mobile cranes...but like Epicur said, those accidents happen fairly often.

This market has been re-opened.

amazing though, the Houston Crane (that collapsed yesterday) was capable of lifting 1,000,000 pounds.
