With cranes being on many construction sites, it’s easy for workers to get complacent. Hundreds or thousands of construction materials can be lifted by cranes throughout the project, but all it takes is one time for a disaster to occur.
A video of a crane collapsing in Austin, TX surfaced on Reddit Wednesday night and shows about a dozen workers running for their lives as it drops the concrete panel wall and falls to the ground itself.
As you can see in the video, at least two of the workers on site are standing on the base of the wall as it begins to be lifted, as if they think their relatively small amount of weight will affect how the wall is lifted. There are 8 visible attachment points on the slab which will control that.
It should be obvious that working around or underneath any suspended material is always a huge safety concern. You will also see in the video that one of the workers is thrown off the panel as the crane starts to fail and has to pick himself up off the ground to run away. The falling concrete wall turns into a large pendulum and almost takes out a couple of the workers nearby.
The cause of the accident appeared to be due to one of the lines snapping, causing the wall to fall and then pulling over the crane. According to the Austin-Travis County EMS Twitter account, 1 man was transported to the hospital with non-life threatening injuries and another injured man refused transport. The injuries could have been much worse, but thankfully they were not.
The video of the accident below was originally shared on Reddit and later posted to Youtube by Adrian Garcia.

The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.
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.
