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.
While being prepared for demolition, the Grand Avenue Bridge in Glenwood Springs, Colorado unexpectedly collapsed to the railroad tracks below. Thankfully, no injuries were reported, but the local police chief said that workers had to flee the scene once the bridge section started to fall.
Directional boring, or horizontal directional drilling, is a common method for installing underground pipe and conduits, among others. Its main benefit is that it minimally disturbs the areas around where your pipe or cable needs to be installed. Instead of cutting concrete, asphalt, or ripping up landscaping, the boring machine digs a tunnel underground and the installing material slides in after it’s complete.
That’s what it’s SUPPOSED to do anyway.
Smoke stack demolitions are always fun to watch because they typically stand much taller than the buildings surrounding them, giving cameras great views of the carnage. They don’t always go well, like when a 2.6 million pound brick stack fell directly on top of an excavator (the operator was fine, by the way), but they’re always dramatic.
Buildings are demolished all the time in order to make way for new construction. The buildings that are demolished have usually lived out their useful life and are no longer functional. Recently a demolition video resurfaced, which shows a 27 story building in China being imploded. The strange thing is that, since it was finished in 1999, the building had never even been used.
There are a lot of people that would be pretty unhappy with whoever tears down a 98 foot tall, 105 year old tree to make room for a building expansion. In order for most projects to work financially, however, many trees are uprooted and replaced with smaller trees. That’s not what happened with what is believed to be the state of Idaho’s largest sequoia tree, however.
As recently highlighted by several multi-story building fires, contractors should always be prepared in the event a fire starts on a job site. There have been dozens multi-story building fires in the past few years and many were started when the building was topped out. In most cases, the project was completely destroyed, leaving developers and owners to deal with years of delays from insurance claims. A massive five-alarm fire at an Oakland construction site is one of the more recent examples.
In today’s race for most powerful cordless tools, it’s important to remember the humble beginnings of hand tools, especially those with mechanical parts. Much like cars of the early 20th century, mechanical and power tools were simple machines, as opposed to the heavily electronic tools that are becoming popular now. Easy to understand and easier to repair.
Two construction workers in Sarasota, Florida were recently trapped 15 stories in the air after one of the lines on their suspended scaffolding snapped. One of the two men was able to be pulled to safety by some co-workers on site, but the second was stuck on the scaffold for an hour before the fire department could rescue him.
Since it opened its doors in 2010, the Burj Khalifa has been the world’s tallest building, one of the most coveted titles in all of the construction industry. If all goes according to plan, the Burj’s reign at the top will come to an end when Saudi Arabia’s Jeddah Tower is completed in 2020.
