Hundreds of news stories have been written recently about the tragic crane collapse in Mecca that claimed 107 lives and injured more than 200 others. The investigations into what exactly went wrong began soon after. On Tuesday, Saudi officials suspended the contractor, Saudi Binladin Group, from new contracts until all legal matters are settled, according to NBC News. Today, Liebherr released a press release statement on their findings after Liebherr crane experts visited the site of the collapse.
The crane that collapsed was Liebherr’s LR 11350 crawler crane, which has a 2,976,000 pound maximum lifting capacity at 39 feet. According to the press release, the crane’s boom was erected approximately 190 meters (620 feet) at the time of the collapse. On the day of the collapse a strong thunderstorm rolled through the area and CNN’s weather service reported winds up to 80km/h (50mph) and a nearby Liebherr Tower Crane recorded winds of 105km/h (65mph). During the time of high winds, Liebherr says that the crawler crane titled over.
“The operating instructions of the LR 11350 and the associated ‘Wind Speed Charts’ show that the crawler crane could not withstand such a high wind load and that the boom should have been lowered to the ground preventatively to avoid the tilting of the crawler crane,” the press release said.

Seattle is in the middle of a construction boom. With that, comes a series of challenges, such as the struggle to fill jobs, an enormous amount of noise that irritates residents, and even a skyline filled with the most out of any other city in the country. That’s right, you may not have guessed it, but Seattle’s 58 cranes lining the city’s skyline are the most in America currently, with the next closest being Los Angeles, California with 40. Amazingly, 58 cranes is also the number currently being used to build one single project oversees: the new Istanbul Airport, which is currently on track to be the world’s largest after completion.
