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!
While placing concrete on the 7th floor of a new hotel in Houston, TX, 16 construction workers were suddenly sent falling to the 6th floor below, sending 9 of them to the hospital, according to local news reports.
As a storm blew through the Dallas, Texas area on Sunday afternoon, a tower crane standing near an occupied apartment building collapsed causing at least one fatality and 6 injuries.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
Over the years, Liebherr, the German Crane Manufacturer, has given us some absolutely amazing videos. For example, they put on a show for their best customers one year and lifted one crane with another crane, which was lifted by a third crane, which was then lifted by a fourth crane. Another video highlighted the 58 cranes that were on site at the same time at the world’s largest airport build in Istanbul. Well, the company is back at it again, this time on top of Europe’s new tallest building.
