Crane story October 16, 2016Posted by WorldbyStorm in Uncategorized.
Bet you don’t know that most cranes (or tower cranes) were developed and built in Europe, well so says the Washington Post, and there’s a…flock of them above Dublin at the moment. The Irish Times recently sent a reporter up one. Got to admit I’m not sure I’ve the head for height to replicate that endeavour.
Still, I was curious about how safe they are. The Post notes that:
The tall and spindly vertical part of the crane is not where the chief hazard lies, experts say. Keeping it upright is easier than it appears.
“It’s pretty elementary; it’s just a matter of balancing forces,” said Henry Petroski, a professor of civil engineering at Duke University and author of a dozen popular books on mechanics and engineering. “The geometry can get a little complicated, but it’s not anything that’s beyond a first- or second-year engineering student.”
It is during these manoeuvres — along with erecting or disassembling the crane — when accidents are most likely to happen, experts say. Running the crane is safe, as mechanisms are built into the controls that prevent the operator from doing things that might destabilize it, such as lifting a too-heavy load.
