Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
In the video below, you’ll see tracked crane attempting to lift a bulldozer up what appears to be a 60-70 foot tall retaining wall. When it gets the machine near the top of the wall, the crane begins to tip and the bulldozer falls back down to the bottom of the excavation. There are also 2 workers that are repelling down the side of the retaining wall as the dozer falls. They both appeared to be uninjured.
It’s unknown whether any injuries occurred, but we certainly hope everyone made it out safe. The only other additional information we have is from the Facebook video description explaining that it happened in Mexico.
This isn’t the first time that we’ve seen a crane collapse trying to raise or lower a bulldozer, either. Back in 2016, we shared a similar video of an incident that happened in Russia.

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.
