Lifts may seem relatively safe, because they move fairly slow, but, believe it or not, there are actually very good reasons that OSHA safety procedures exist, especially wearing a harness on a lift.
In the video below, posted to Youtube by Jumalten001, you’ll see a man try to maneuver a boom lift past what appears to be about a two foot tall concrete ledge. After the front set of tires successfully hit the ground, you can see the man have to brace himself in the basket. After that happened, you would think that he would have given the back wheels a second thought, but he powered through. After the second set of wheels hit the ground below, the boom lift bounces and launches the man in the air about 10-15 feet high and he hits the basket awkwardly as he falls. There’s no doubt that this could have ended much poorly for the man, but the fall could have also been avoided if he had been properly tied off.
OSHA regulations 29 CFR 1926.451(g)(1) and 29 CFR 1926.451(g)(4) state the rules regarding personal fall arrest systems requirements on lifts and scaffolds.
Remote jobsites with difficult terrain pose some substantial logistical challenges when it comes to getting equipment and materials on site. I’ve seen several different methods used in the past, such as heavy equipment carrying blimps, cargo planes, helicopters, and the Fat Truck, but I recently came across a new method: a cable car.
In November of last year, the 546 foot tall Mina Plaza in Abu Dhabi officially broke the world record for tallest demolition by explosion, supplanting Hudson Department Store in Detroit, Michigan, which held the record for 22 years.
If you need to get some heavy mechanical equipment on the roof of your project, you could use a boring old crane – or you could gas up the bird and make that equipment take literal flight. Alright, so cranes aren’t actually boring, but some times a helicopter makes more logistical sense, either because it reduces total lift time or, in some cases, makes economical sense. Either way, there are some important safety precautions to take in case something goes wrong.
2020 was a stressful year, so let’s decompress a little bit by reviewing some of the most fun demolition videos from the past year. A demolition that broke a 22 year old record highlights the bunch and I also stretch what the definition of “demolition” is a little bit, because I think the video is so cool. Don’t @ me.
Without further ado, here are the top 7 demolition videos from 2020:
2 years ago, crane manufacturer, Sarens, unveiled what is considered to be the world’s largest crane, by both size and lifting capacity. Big Carl, as the huge crane was nicknamed, began work a few months later on the Hinkley Point C nuclear power station in England. Now, the jobsite boasts an abundance of crane activity, a true site to behold, and it was captured on aerial footage for you to enjoy.
Back in 1998, the Hudson Department Store in downtown Detroit, Michigan was demolished by explosives. That building stood 410 feet tall across its 29 floors, making it, at the time, the tallest building to ever be taken down by implosion. The dust cloud covered many city blocks and the 20,000 unsuspecting people that came to watch the event. That record was just recently broken by a building over 100 feet taller than it.
Excavators aren’t typically meant to be dropped down to a lower level, but certain circumstances require it sometimes. The machines are obviously extremely heavy, so a large crane and proper rigging is required for it to happen safely. As a construction firm in Hong Kong, China recently found out, though, it’s a little tougher than it seems.
Usually, when a new development is going to go into a spot where a building already exists, that existing building gets blown into smithereens and its remaining rubble hauled away. BUT, there is apparently a different way to handle the situation now, which is by politely asking the building to walk away and to find a new home – well, kind of.
CAT is no stranger to finding extremely creative and expensive ways to show off their construction equipment. In years past, they’ve created a giant Jenga game with 600 pound blocks and the world’s first moving golf course on the backs of their dump trucks. Now, they’re showing off some of their new technology with the release of the biggest PAC-MAN game you’ve ever seen.
On Tuesday morning, February 23, the Syracuse Fire Department responded to a call about a collapsed crane on a construction site near the university. Thankfully, no injuries were reported.
