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.
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.
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.
As we’ve seen in the past, demolitions aren’t all about implosions. There are still many manual demolitions that are carried out by skilled excavator operators. The Victoria Street Bridge in Ontario, Canada is a recent example of that.
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.
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.
Cameras are EVERYWHERE these days. They’re on sites documenting the full construction process of your project, they’re on projects taking 360 degree progress footage, and most importantly, they’re in your pocket on your smartphone. Having a camera in your pocket at all times can be a good or bad thing, especially for employers, because not only can it make lives much easier for communication and documentation purposes, but it also gives people the chance to show the world when things go absolutely terribly.
With cranes being on many construction sites, it’s easy for workers to get complacent. Hundreds or thousands of construction materials can be lifted by cranes throughout the project, but all it takes is one time for a disaster to occur.
In regards to timelapse videos, it was a big year for sports arenas and the city of Atlanta, Georgia. These types of videos have become more popular in recent years due to the wide availability of documentation services available. Not only that, but civilians who own drones have also taking a liking to their area’s construction sites.
