A bridge needs to be built, so time to bust out the cranes, right? Not so fast, a Chinese company has built a machine that has a creative way of setting girders into place.
The SLJ900/32, made by the Beijing Wowjoint Machinery Company, is a 580 ton, 300 foot long and 24 foot wide mega machine that looks more like a train than a crane and acts a lot like a Stretch Armstrong action figure. Instead of using a stationary or crawler crane to lift the girder of a bridge from the ground and drop it into its place, the SLJ900/32 drives the girder onto the previously placed girder, slowly extends its arms to the next support platform, pushes the girder towards the front of the machine and then lowers it into place.

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.
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.
