The load proved heavier than expected
9. September 2017
A crane overturned onto a home in the Brookhaven, suburb of Atlanta, Georgia on Thursday while removing a large oak tree from the back garden/yard.
It seems that the crane, a three axle Liebherr, was simply overloaded when the tree section it was given proved to be heavier than estimated.
The crane was lifting directly over the rear with the outriggers well set up on mats. The homeowners were in at the time but thankfully no one was injured in the incident.
The home though sustained considerable damage as the crane boom sliced into it.
The damage to the home is substantial

Lifting trees has to be by far and away the load that causes the most crane overturns, bar none. Surely the messages has to be never trust a tree workers estimate of the weight he is about to unleash on the crane.
