Wrecking balls got a big publicity boost in 2013 when Miley Cyrus released her hit song, but, they’re not really that popular with regards to demolition. Wrecking balls are slowly becoming extinct in the construction industry, making way for more precise hydraulic excavators and explosives. Made of forged steel, wrecking balls typically range between 1,000 to 12,000 pounds. Needless to say, they’re big, they’re heavy, and they don’t belong around operating streets and buildings. Which leads us to the video below…
If a 1-12,000 pound wrecking ball free falling from a crane can demolish a concrete building, just imagine the damage it can do to a moving minivan. The result, which you can watch below, isn’t pretty. The minivan never stands a chance.
Depending on your reaction to the video, this next paragraph may either be a relief or a total bummer. The fact is, a quick Google search revealed that the video above is from the set of the movie “The Other Guys,” which starred Will Ferrell and Mark Wahlberg. Though it may be a staged accident on a movie set, it’s yet another example of the size and strength of equipment throughout the job site. Much like this mining truck running over an SUV for a safety video, when construction equipment is mixed with the public, catastrophes can happen. Being aware of your surroundings can make all the difference.
Mistakes during demolitions happen. Sometimes contractors knock down the wrong buildings, other times the explosives used don’t knock the building over, and other demolitions are carried out with a complete lack of regard for human life. As fun as they are to perform and watch, they’re inherently dangerous and there should be a plan in place in case things go wrong.
Cranes collapse for a variety of different reasons. Some are overloaded, some catch on fire, and others succumb to high wind loads. Regardless of the reason, a falling crane can cause tons of damage and have the potential to kill on-site workers and pedestrians walking near the job site.
A recent crawler crane collapse in Northern Italy could have been much worse as the crane, carrying a large section of viaduct, crashed to the ground.
Construction Junkie has shared a lot of demolition videos. Typically, people line up waiting for the moment when the building explodes with their eyes peeled and cameras ready, just waiting for the perfect video. This video, however, is much different.
Doing something in the name of revenge typically is never a good idea. Concrete truck operators getting involved with that revenge is probably an even worse idea. But, anger makes people do weird things, including video taping said revenge.
As harmless as it looks, dirt can be one of the biggest hazards on any construction site. It’s heavy and is bound to collapse without warning unless proper safety measures are taken into account. Landslides are essentially no different than trench collapses, without proper shoring or sloping, you could be putting worker’s lives in danger.
Nobody likes having something stolen from them, obviously, but some people are also more willing to go to extreme lengths to get their items back. Construction sites are hot targets for thieves, because there’s typically thousands of dollars worth of tools and material on site at any time. On one construction site in Dallas, an alleged thief thought he was going to snag a tool from the site and drive away safely, but several construction workers had a different thought in mind.
Other than at the zoo, there aren’t many options for Americans to come into contact with a rhino. It’s also becoming increasingly rarer to come into contact with them in their native countries. Black rhino populations, like other rhino species, have fallen drastically since 1970. Savetherhino.org estimates that in 1970, there were around 70,000 black rhinos in Africa, but now there are only around 5,000.
Remote sites have extreme challenges, like finding enough staff to work the jobs and being able to get materials to the site. Large mining operations have turned to self-driving dump trucks, like this 320 Ton mega machine, for a few years now. But, Lockheed Martin, a giant in the world of global security and aerospace, has a different solution for remote sites.
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.
