9 Day Old Crane

Friday Morning Sept. 26 2008 - Castle Hill/Sydney

9 Day Old 250t Liebherr Crane (never used before)
$4mill price tag (USD or Aussie?)


Failure of back propping beneath the 200mm thick concrete deck
Crane support outrigger punches through slab causing crane to lose balance and collapse across the site and onto adjoining property


Crane balanced in the air for approx 1 hour before entire rig & boom collapse completely across site and rigs falls through to the basement level.





Miraculously no one was seriously injured or killed.

"Miraculously no one was seriously injured or killed."

Until the foreman kills someone with his bare hands.

Somebody pulled a fast one with the concrete, I wouldnt of drove her out there on it. Engineers and their degrees huh, and the stress load is?, Could you even imagine having to call your BOSS on this one. (No I really think you need to get down as quick as possible, theres been a situation.)

Yes I thought it was the new big fire truck that had fallen thru one of the old streets in town. One of them with the old 1800's sewer systems we have here in the city.

The operator, whether any "engineer" told him it was ok, should have known better. I had a 300t similar crane on a local job. Sitting on our hard pack sand in Salisbury, he pot down the outriggers with 4 foot diameter pads, and I watched in wonder as they pushed four inches down before the crane began to rise! When it left the site, it had to drive over the sidewalk, which was 6 inches above the street at the curb. As it drove over, it left the concrete sidewalk level with the street. The sheer weight of these things is incomprehensible, let alone the weights they add when they pick up a load!

9:59, where is Salisbury was there a use for a 300T crane? I know there was a big one at the hospital about 9 months ago.

I have never seen a crane that size put down outriggers into sand without having 20-30 foot long bridge mats under them. It is a wonder it didn't tip over if it really was that large.

It was at the hospital; he just put them down for stabilization during disassembly, not to pick a load.
