There’s no doubt that construction industry has some very impressively sized and powerful machines out there and unfortunately not many of us get to actually use them. Since most of will never be able to drive one of these, we can at least marvel at videos of them. Youtuber JD Rock recently put together a video compilation of the 10 largest construction machines in the world, which you can find at the bottom of this post. To help you understand just how big these things are, the descriptions of each will be listed directly below this paragraph.
Primarily used by mine operators in the US, Canada, and Australia, Komatsu’s D575A is the largest bulldozer in production and has been since its inception in 1991. It boasts a 1,150 horsepower engine and is able to move 90 cubic yards per pass.
The 160,000 pound L-2350 holds the Guinness World Record for Biggest Earth Mover with its lifting payload of 72 tons. The massive loader has a standard bucket of 40.52 cubic meters and a 2300 horsepower engine.
The always impressive Liebherr, manufacturer of some very impressive cranes, also boats one of the largest bucket excavators with their R 9800. Another machine typically used for mining, the 9800 weighs in at 1,785,700 pounds and have a bucket capacity of 62 cubic yards. That could save a lot of time digging out the pool for the back yard.
#7 Belaz 75710
The Belaz 75710 actually recently supplanted the CAT 797F dump truck (which you can see being assembled from start to finish here) as the world’s largest. Standing 26 feet tall, the 450 ton haul truck is powered by two separate 65-litre engines, each with 2300 horsepower.
Though the Hitachi EX8000 is shown in the video, the CAT 6090 is actually slightly bigger. With an operating weight of 1,080 tons, the 6090 is powered by a massive 4,500 horsepower engine.
Electric rope shovels are built to be able to remove large amounts of overburden and ore more efficiently that other loaders. The 109 ton 4100XPC sits 48 feet tall and can haul up to 82 cubic yards
Weighing in at a whopping 10.4 million pounds, the 2570W can dig to a depth of 140 feet and has a boom length of 310 feet. It’s certainly not a speedster though, with top walking speeds clocking in at 0.15 mph. It certainly won’t be stealing any bases soon.
The 50 year old crawler transporter are actually being modified in 2015 to assist in the launching of the space shuttle that will take us to Mars. These massive 131 feet long and 114 feet wide weigh in at greater than 6 million pounds and carry NASA rockets from site to site…at 1 mph. One of the two crawlers in existence has traveled 2,207 miles in its lifetime, which, if my math is correct, took 2,207 hours.
The title of world’s largest tunnel boring machine is actually held by “Big Bertha,” which is 57 feet in diameter. It was specifically built to dig underneath the city of Seattle, Washington for a 2 mile roadway, but broke down in the middle of the project. It's estimated that it will take another 2-3 years to make the necessary repairs.
The Bagger 293 is not only the largest excavator, but also holds the record for the largest land vehicle in the history of the world. At 310 feet tall and 721 feet long, the 4 year old German machine can move 100,000 cubic yards of dirt per day with the use of its 20 rotating buckets.
For some reason, there are plenty of people out there willing to try their hand at the “hard hat challenge,” in which worker’s attempt to launch a hard hat onto their head by stomping on a shovel, a 2x4, or any other launching mechanism. It all seems like fun and games until the wrong side of that hard hat ends up hitting you on top of the head, which seems to happen EVERY TIME.
Sometimes the way to do something doesn’t have to be the toughest way. Slipping overboots on over your work boots seems less like “slipping” and more like “jamming” and “forcing” some times.
Kids say the darndest things…so much so that there was a whole TV show made about it. Kids never really quite understand exactly what adults do for a living, so it’s really fun to hear about the little things they pick up on and then watch them try to put the pieces together.
As we have highlighted before on Construction Junkie, China has shown us what a model for efficiency is when it comes to large infrastructure projects. That being said, they seem to be creating a lot of one-off, gargantuan pieces of equipment to do so. In the video below, we see the Sanyuan Bridge in Beijing get entirely removed and replaced with a new bridge in 43 hours.
The most terrifying thing on a job site is when workers get creative with heavy machinery. Sometimes it works out and nobody thinks anything of it, but, if they’re not extremely careful, chaos can’t break loose.
Just in time for Halloween, here’s a video of a bunch of dirty rats living below a concrete slab in Brazil that a group of lucky contractors had the pleasure of uncovering. As the crew broke up piece after piece of concrete, more and more rats scurried out in a hurry, much like that scene in the movie Ratatouille, when hundreds of rats fell out of the ceiling. At least those were animated.
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.
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.
There are many classic pranks that construction workers pull on the new guy on the site, such as being sent to find a left handed hammer or a light bulb repair kit, but this one might just be the most tiring.
Building implosions are always fun to watch, although sometimes they just don't go quite right. So when companies can accurately control a demolition and have two structures hit in mid-air, it's a thing of beauty! The Cockenzie power station in Scotland has two 487 foot tall chimneys and when it came time to demolish them, there was no better way then to have them strike mid-collapse.
