This video is a bit of a throwback, but I recently came across it on the interwebs for the first time and thought it was worth a share.
The incident below happened almost 10 years ago at the Wesfarmers Curragh coal mine in Queensland, Australia. According to the Sydney Morning Herald, the boom of one of the site’s 5 draglines was being lowered by four cranes. The boom ended up free falling around 100 feet when one of the crane’s winches failed.
As with most crane collapses, damage doesn’t stop with the crane itself. As the Youtube poster, malaycobra, points out in the description, “as you can see the correct radius hadn't been chosen to let the drag line boom clear the M4600-based Transilift boom.” The poster also notes that the official report after the incident cited “operator error” as the cause.
One of the crane operators was injured and it’s believed that his injuries were minor. HLI Consulting posted several up close pictures of the aftermath of the crane collapsed on their Flickr page, which you can check out here.
WARNING: there is strong language in the video...
While placing concrete on the 7th floor of a new hotel in Houston, TX, 16 construction workers were suddenly sent falling to the 6th floor below, sending 9 of them to the hospital, according to local news reports.
As a storm blew through the Dallas, Texas area on Sunday afternoon, a tower crane standing near an occupied apartment building collapsed causing at least one fatality and 6 injuries.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
Over the years, Liebherr, the German Crane Manufacturer, has given us some absolutely amazing videos. For example, they put on a show for their best customers one year and lifted one crane with another crane, which was lifted by a third crane, which was then lifted by a fourth crane. Another video highlighted the 58 cranes that were on site at the same time at the world’s largest airport build in Istanbul. Well, the company is back at it again, this time on top of Europe’s new tallest building.
