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.
Falls on the jobsite is the leading cause of injuries and fatalities in construction. Keeping up with housekeeping on your site is a great way to reduce risks of falls, but other protections, like rebar caps should be installed when rebar is exposed. A young construction worker recently found out the hard way what happens when rebar is left exposed.
Completed in 1976, the CN Tower in Toronto, Canada held the record for the tallest freestanding structure in the world from 1975-2007, until it was supplanted by Dubai’s Burj Khalifa. At its highest point, the CN Tower, which is mainly used as a communications and observation tower, reaches 1,815.4 feet (533.33m). Last year, the tower underwent a $16 million renovation and Priestly Demolition shared a fascinating, in-depth video for how they took care of the demolition of the interior space and walls.
Cranes collapsing on-site are serious business, especially since many of them resulted in the loss of life. A recent crane collapse on a construction site in Alpharetta, GA was caught on camera after it caught fire, but luckily no one was injured.
There are a lot of different specialty construction contracting sectors within the industry and cruise ships are definitely one of them. There are plenty of unique challenges when dealing with a moving ship versus a static building. A recent accident highlighted the challenges when a crane collapsed on a cruise ship under renovations, injuring 8 people.
Almost 7 years ago, construction began on the west side of Manhattan’s $20 billion mixed-use development. On March 15, 2019, Hudson Yards, as the development is known, has officially opened.
Demolitions by implosion can be fun to watch when they go right – or wrong – but nearby residents can be greatly affected by the high powered blasts and huge clouds of debris that follow. A few years ago, a botched demolition in England left dozens of nearby residents unable to return to their homes for several days. Last week, an obsolete Steel Basic Oxygen Plant in Weirton, West Virginia is leaving residents in a similar situation.
Traditional safety training for construction workers includes OSHA 10-hour or 30-hour courses, toolbox talks, and safety inspections. Those training techniques are all important and necessary, but construction workers are an extremely hands-on group of individuals and putting them in real life situations can be much more beneficial to them instead of classroom training.
Over the years, Liebherr, the German Crane Manufacturer, has given us some absolutely amazing videos. For example, they put on a show for their best customers one year and lifted one crane with another crane, which was lifted by a third crane, which was then lifted by a fourth crane. Another video highlighted the 58 cranes that were on site at the same time at the world’s largest airport build in Istanbul. Well, the company is back at it again, this time on top of Europe’s new tallest building.
When we think about historic buildings of ancient times that are still standing, we can stand in awe of the level of detail that was incorporated into designs without modern tools and technology. For a few decades, it seemed like we would never see that type of character in buildings again, but sports stadiums are becoming new modern wonders, pushing the limits of not only what’s capable from a construction standpoint, but also the budgets.
