The most popular method of demolition these days is by implosion, but not always welcome in certain areas or situations. The use of explosives can greatly damage neighboring buildings and spread hazardous materials over a large radius, which is why a cooling tower at the Mülheim-Kärlich power plant in Germany had to be slowly dismantled from the top.Read More
After causing devastation in the Bahamas, Hurricane Dorian worked its way up the U.S. East Coast last week and eventually made its way up to Nova Scotia, Canada as a Category 2 storm. The storm left more than 369,000 without power in the Canadian Region, according to CBC, but also caused a tower crane to buckle and collapse in the city of Halifax.Read More

One of the most important rules of safety is using the correct tool for the correct job. Steep slopes can be a dangerous obstacle for many pieced of heavy equipment on a jobsite, as made clear by the various videos passed around the internet showing machines tumbling down embankments.
I recently ran across a machine called a Spider Excavator that is specifically designed for work on difficult terrain. One is currently being used on a California Transportation (Caltrans) project along State Route 2 in order to clear an area after a mud slide.
Slides have to be cleared from the top down, so the use of a spider is extremely useful. Equipped with wheels and a total of 4 outriggers, the machine is able to climb up hills safely by setting the bucket down and push itself up.
Not everyone will need a machine like this, but those who need it will be happy they have it.
Check out the video of the excavator in action below:

On Saturday afternoon, tragedy struck downtown Seattle as a tower crane that was being dismantled suddenly fell to the street below, killing two ironworkers and 2 people that were in their cars, as well as injuring 4 others. Dashcam footage of that collapse has recently surfaced, giving some clues as to why the crane fell as it did.
After reviewing the video and pictures from the scene, many believe that the pins, which secure the tower crane sections together, were pulled prematurely. King5 News reports that experts point to the fact that the base section of the crane did not move at all. Many initial reports pointed to wind gusts that rolled through the area, but it now appears that the wind only played a small part as the structure was significantly weakened.
In King5’s story, attorney David Kwass, who has worked on the litigation for crane incidents in the past, drew comparisons to a 2012 crane collapse in Dallas. In that case, many thought the wind was a big factor, but it was later discovered that the crane had been prematurely de-pinned.
As the investigation rolls on, let’s not lose sight of the fact that 4 people lost their lives and many others will be affected by witnessing the incident for years to come. King5 also reported that the victims were 33-year-old Travis Corbet and 31-year-old Andrew Yoder, both ironworkers, as well as a 19-year-old college freshman Sarah Wong and 71-year-old Alan Justad.
The video of the incident shared on YouTube is below.
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.Read More
