Large Crawler Crane Lifting Viaduct Section Goes Wrong
Northern Italy. 9 May 2017. A crane, owned by Vernazza, was rigged with a back mast and suspended superlift counterweight was lifting a large section of a new viaduct at the Arcisate Stabio railway yards, near Varese when it appeared to the rear of the tracks came off the ground and after seeming be on the point of balance for a while before it finally lost stability and overturned dumping its load. The operator managed to jump clear as the crane went over and is uninjured and that no one else was caught up in the incident.   |

As long as nobody got hurt, it's just entertaining. (The ancient Romans used to do this, without any crane, and they never dropped their viaducts.) |

Seems to me they didn't have quite enough counterbalance and/or the load was much too heavy for the crane.

Re: Large Crawler Crane Lifting Viaduct Section Goes Wrong
I don't know the math involved, but just looking at that, my gut says the counterweight is much too small. Apparently I'm right.  |

They didn't give themselves any room to raise the counterweight and/or lower the boom it was on.

Re: Large Crawler Crane Lifting Viaduct Section Goes Wrong
That was an impressive catastrophic failure to be able to see happen. I rewatched the video several times to see all the nuances and was specifically looking for the operator whom I saw barely dodging falling debris. Impressive indeed.

Somebody has obviously fucked up the calculations for this lift. There should be a 50% safety margin for the whole operation. |
