A lot of safety discussions center around how to keep yourself from falling off or being launched from lifts, but not many safety discussions involve how to get off of them when you’re in danger. Just recently, two construction workers in Boise, Idaho had to make some quick decisions as their welding blanket caught fire while they were in the lift.
At the time of the fire, the boom lift was extended roughly 60 feet in the air and they were too far away from the building to be able to jump to safety. Worse yet, the control board on the basket no longer was disabled due to the fire. As the flames started to get larger, quick thinking workers on ground level were able to swing the basket towards the building, which allowed the two men to jump to a ledge on the sixth floor. The two men were able to get away with only minor burns and were treated for smoke inhalation and KBOI in Boise reports they are doing well.
I’m not sure there are many situations than being trapped by a fire, but these two aren’t the first to have to jump to safety to avoid being badly injured. Dramatic footage of a construction worker trapped on a 5th floor balcony of a $50 million Houston apartment complex engulfed in flames was caught on video in 2014. In the video, you can see the worker lowering himself down the fifth floor balcony and swinging onto the fourth floor balcony, where he was rescued by a team of firemen. That building, which was nearing completion, was completely destroyed by the fire.
Luckily for the crew at the recent Boise job site, the fire was able to be contained within the basket of the lift. It’s a sobering reminder that job sites can and do catch fire and split second decisions need to be made in order to save lives when it happens.
Below is the raw video footage of the men jumping off of the lift:
Below is the full news story from KBOI:
Early this year, a landslide caused catastrophic failure to the Pfeiffer Canyon Bridge along California’s famous Highway 1. California Transit officials closed the bridge on February 21st and announced it would be demolished and replaced. Time is of the essence as US News reports that over 400 residents are stranded on one side of the bridge and helicopters have had to bring in food for them. The residents are still able to use the footpaths in the area to cross the canyon.
If you’re into heights, then China may be the place you need to be. The country recently unveiled the world’s highest and longest glass bridge and, as scary as many tourists may find that, it was way more dangerous while it was under construction. New footage of another construction site in the Laowang Monutains is giving that bridge a run for it’s money.
There’s no doubt that bridge demolitions by implosion are extremely fun to watch, but the fireworks show and big splash into the water below can sometimes overshadow other demolition projects that don’t allow implosion. Priestly Demolition Inc. (PDI) recently won two 2016 World Demolition Awards for one of those projects where implosion was not an option and they have also produced an incredibly detailed video of how they did it.
Since Construction Junkie was conceived in 2015, we’ve seen a lot of construction equipment flip for some really stupid reasons. Like this crane, this other crane, and this third crane dropping a bulldozer. Those are just some of the ones caught on video and they should be enough to convince you not to go out of your way to do dangerous things with a crane.
Rowlett, Texas was hit hard by a tornado in 2015 and the city is still dealing with the effects of it. In the horrible storm, 13 people were killed and over 400 buildings were damaged or destroyed, according to CBS DFW. In a story we covered last year, one Rowlett woman also had her house mistakenly knocked down by a demolition company when addresses got mixed up after the tornado.
In an incredible fight for his life, excavator operator Daniel Miller, of Australia, spent 2 long hours trapped by his excavator with only his nose and forehead above water. Amazingly, the man survived and his wife says it was due to his sheer mental strength and will to survive.
Cranes are a staple of many construction sites throughout the world, but they’re susceptible to damage caused by sudden bursts of high wind. Winds were blamed for the collapse of the New York City crane collapse that killed one man and injured 3 others in 2016 and again for the devastating crane collapse in Mecca, which killed over 100.
Much like the stories above, a crane collapsed last week in Dubai, UAE, after sudden heavy winds burst through town.
You might be operating some big machines on your construction site, but, chances are, none of them can come close to the Bagger 288 bucket wheel excavator. There’s probably an excavator on your job site right now, but imagine the work you could get done if you have a machine with 18 buckets, each with a capacity of 6 tons. That’s the capacity of the massive 30 story tall ThyssenKrupp Bagger 288 bucket wheel excavator.
We saw some pretty awesome demolition videos in 2016, like this super slow motion bridge demolition and this video of 116 excavators working side by side to demolish an overpass overnight, but this new video is already on top of the leaderboard for best demolitions of 2017.
Steel rebar, the world’s favorite reinforcement material for concrete, greatly increases tensile strength in concrete. Due to concrete’s rigidness and tendency to shrink and expand, reinforcement is necessary in many cases to reduce cracking and slow structural failure. This material is elementary to most of throughout the construction industry, but what you may not be familiar with is how much stress steel rebar must be under before it completely snaps in half.
