We’ve touched on several of the biggest and baldest construction machines in the past, like this 800 ton excavator and this 600 ton haul truck. While videos about these gigantic machines are fun to watch, they also truly put into perspective how many people and time goes into creating and assembling them.
In this post, we’ll be looking at Joy Global’s P&H L-2350, originally designed by LeTourneau Technologies, which currently holds the record for the world’s largest of its kind. At an operating capacity of 160,000 pounds (72,574 kg) and a total payload of more than 400 tons, this magnificent beast has a bucket capacity of 53 cubic yards (40.52 cubic meters).
When the designers set out to design the 2350, they couldn’t even find wheels big enough to work, so they had to team up with Firestone’s engineers to specially design a 13 foot tall tire, which also happened to be the world’s largest tire.
As you can imagine, this loader requires a lot of power to operate and even more fuel. The engine produces 2300 horsepower, which is turbo-charged and consumes roughly 50 gallons of fuel per hour. The total fuel tank capacity is around almost 1050 gallons (3974.68 liters).
According to ExtremeTV, who uploaded the video to Youtube, the price tag on the 2350 was $1.5 million in 2012.
It’s a tale (tail) as old as time: a horse walks into a construction trench, gets stuck, has to be lifted out of it by a helicopter. The trench didn’t appear to be that deep, so I don’t think OSHA is going to need to get involved with this one.
For the third time in a year, construction workers have had to be rescued while dangling mid-air by fire rescue teams in Southern Florida. Last year, there were two incidents in Sarasota, Florida that involved failed suspended scaffolding in as many months. Just last week, another incident in Palmetto Bay required the Fire Department to intervene.
Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
Crane collapses on construction jobsites are usually pretty terrifying, especially when the jobsite is full of workers. A construction site in St. Petersburg, Florida got extremely lucky when a large construction crane collapsed and narrowly missed several running workers.
This video is a bit of a throwback, but I recently came across it on the interwebs for the first time and thought it was worth a share.
It’s been a while since we have shared a demolition video on Construction Junkie. We recently discussed a very high profile demolition project, the tallest voluntary demolition on record, which is schedule to start next year and how it is expected to happen, but no videos. Between the cold weather in most of the country and the general lack of interesting demolitions happening, it’s good to finally be back to feeling normal around here.
Last Thursday, every construction professional’s worst nightmare happened. Lives were lost, both construction workers and civilians, by way of the catastrophic collapse of FIU’s under construction pedestrian bridge. We shared what we knew as of late Thursday night, but since this is not only a tragedy directly related to construction, but also a huge learning opportunity for the entire industry, I wanted to make sure we continued to follow and update on the story as it develops.
Terrible tragedy struck Florida International University’s (FIU) campus yesterday when a newly installed pedestrian bridge collapsed onto the road below, killing at least 4 and severely injuring many more.
It’s pretty amazing the work that can get done when a lot of resources and money are thrown at one project. Past examples of this include a gigantic sinkhole that was repaired in Japan in just under a week, the complete emergency rebuild of Atlanta’s I-85 overpass that was completed a month ahead of schedule, and this video of 116 excavators working side by side to demolish a 1,640 foot long overpass overnight.
When anyone sees a hard hat, they typically immediate associate it with construction. It’s the ultimate symbol of safety on the job site. We all know we should wear them, but it’s easy to get annoyed with the minor inconvenience that they cause and forget about the extreme consequences that could result if a falling object catches us when we aren’t wearing one.
