You’ve probably seen an excavator most days of your life, especially if you work in construction, but, unless you work in the mining industry you’ll never see something as big as the Liebherr R 9800, a roughly 800 ton excavator. Standing at 36’3” high, 28’9” wide, and 83’0” long, this mega machine can load 75-93 tons of material per pass. According to mining-technology.com, the R 9800 is the third largest excavator in the world, behind only the Hitachi EX8000-6 and the Bucyrus RH400.
As you can imagine, something that large takes quite a bit to assemble and cannot just be shipped whole to your job site. This particular machine had quite the journey to get to site. First, it traveled by sea from the production site in Colmar, France to Australia. From there, it was hauled, in pieced, by trucks another 169 miles (272 kilometers) to its job site at the Moolarben coal mine. It’s a total logistical nightmare, but the folks at Liebherr were able to get the job done using several cranes to lift the extremely heavy pieces and even more men to make the final connections.
To see the Liebherr R 9800 in action, look no further than the video below, uploaded to Youtube by Bauforum24!
A construction crane that was working on a highway widening project in St. Martin Parish in Louisiana collapsed onto the adjacent roadway last week, injuring one driver.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
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.
As the US is experiencing our own natural disaster, by way of Hurricane Florence, China is being hit badly by a Typhoon Mangkhut. According to Independent, the storm has caused a crane, which was being used on a 22-story housing development, to crumble. That collapse was caught on camera by neighbors.
There have been a few devastating structural collapses across America and the world this year. In March, an under construction pedestrian bridge collapsed in Florida, killing 6. In Colombia, ten workers were killed when a large section of a bridge being built collapsed. Both of those tragedies happened while the structures were still being built, but a recent collapse in Texas has a bit of a different story.
If you’re a general contractor in the Davie, Florida area, I have an idea why one of your deliveries might have been late last week.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
In January of 2018, ten construction workers were killed and another eight were injured when a bridge spanning the Chirajara canyon in Columbia partially collapsed. That collapse has since been blamed on a poor design, reports have stated. Last week, the remaining sections of the bridge were demolished in dramatic fashion.
A 47 year old crane operator is facing charges of driving while intoxicated and leaving the scene of an accident after driving a truck mounted crane into several vehicles on the Long Island Expressway in New York.
