“I heard a loud boom. I saw this big crane, and it went into the neighbor’s yard and is crushing the house,” said Patricca Davis, a resident and witness of an unfortunate crane accident which happened in the Lauderhill area of Florida on May 31 2018. According to the news sources, the crane fell over and its boom crashed into two Lauderhill homes, leaving a resident and the crane operator with minor injuries. During operation, at some point, the crane lost its stability and fell towards the houses.

While the respective residents and crane staff are expressing gratitude to God till today for saving their lives, the proliferation of worldwide crane accidents and related losses in the construction sector are a matter of concern for everyone. However, labor organizations like OSHA (Occupational Safety and Health Administration) has implemented strict measures and recommendations regarding cranes, derrick and hoist safety.
Let’s go back in time and study notable crane accidents that have happened worldwide over the past few years:
“Big Blue”, Wisconsin, July 1999
At some point during the construction of the Miller Park baseball stadium in Milwaukee, the ‘Big Blue’ crane collapsed with a load of over 450 tonnes on the hook. The incident happened on the miserable evening of July 14, 1999, killing 3 ironworkers. The cause of the accident was due to a large force of wind which was not considered for the load the crane was lifting, despite climate warnings by some of the field workers. This is one of the largest accidents to have happened in the history of cranes. The memories still haunt those who were witnesses of the ‘Big Blue’ tragedy.

2. Bellevue, Washington, November 2006
On November 16, 2006, a 210-feet tall tower crane toppled from a construction site and collapsed damaging three buildings and killing a resident inside the top floor. The crane operator suffered minor injuries. According to the L&I (Labor and Industries) Department of Washington State, the cause of the collapse was metal fatigue of the steel base frame, which was not strong enough to support the working crane.
