If the tire on your car gets punctured, you might be stuck waiting at the maintenance shop for around an hour for the hole to be patched. But, if one of your $30,000 heavy duty earthmoving tires develops a hole, you’re going to be waiting much longer.
The video below shows the entire process of repairing a relatively small laceration in an earthmoving tire, using a process created by REMA TIP TOP. REMA supplies automotive and industrial products, including the OTR Tire Retread Product, highlighted in the video, which are made in the company’s Madison, GA plant.
As you’ll see, the repair requires a heck of a process to complete, which starts by making the small hole into a large crater. After the patch is cut in and applied, a series of taping, gumming, and stitching techniques keep the patch in place. It’s a long and tedious process that clearly requires a lot of precision and quality, so we can take solace in that fact that we’re not the ones that have to do the work. There is a significant part of the tire repair process that was cut out of the video, however, which is the vulcanization process, which hardens the rubber by heating it at high temperatures with sulfur.
If you’re interested in some general best practices for maintaining your large equipment tires, OTR Tires provided some good tips on their website. Many of the tips, like checking tire pressure regularly, checking tread depth, and avoiding potholes, are pretty obvious, but others are good reminders. Maintaining proper speed, for example, isn’t just a good practice for safety, each tire also has a recommended speed limit that should not be topped. If you’re storing your tires, make sure it’s for no longer than 90 days and in an area that does not get extremely hot or cold.
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.
As America’s infrastructure is continually described as “crumbling,” I thought it would be a good time to take a look back to how highways were paved around 70 years ago. A lot has changed in the past seven decades, but you might be surprised by how similar paving still is.
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.
One of the best parts (for me, anyway) of large developments that cost hundreds of millions of dollars being built is being able to learn about different construction methods that can reduce costs or deliver the project sooner than traditional methods. The Crown Sydney, a future 890 foot tall tower in Australia, is using a method called “top down construction” to shorten their project schedule and avoid additional hazards on the $740 million project.
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 couple weeks ago, we shared a list of the 100 tallest buildings to ever be demolished. One of the most interesting things that I learned while researching for that article was that although Detroit’s Greater Department Hudson Store was not the tallest building on the list (it was #21), it was the tallest on the list to actually be imploded.
Back in September of 2017, the $100 million renovation of the Seattle Space Needle began with the installation of a 28,000 pound scaffold system ring designed to circle the famous saucer shaped top of the Needle.
One thing’s for sure, the only thing better than one structure being demolished is two structures being demolished at the same time. Late last week, a decommissioned Florida Power Plant saw to the implosion of two 462 feet tall cooling towers in spectacular fashion.
Learning to tie several useful knots has been on my to-do list for a while now and I’m reminded of that every time I tie some insane knot that’s way too loose or nearly impossible to un-tie. I guess one of my my biggest hurdles is figuring out which knots would be most useful for me.
Construction crews were preparing to replace window glazing on the 47-story tall Wellhouse na Leninskom tower in Moscow, Russia, when a cable snapped just as the window was about to reach the top of the structure
