Here is another example of a crane overturning while helping remove a tree, this time in Largo, Florida, on Sunday. This time it involved a 20 tonne boom truck painted in the livery of A-OK Crane Service of Tarpon Springs.

The company specialises in tree work and knows how tricky it can be. It seems that in this case the crane was lifting a substantial section of the tree and had started to slew when the crane overturned. The outriggers remained solid, so it looks as though it was a classic overload – either actual or dynamic as the section twisted and moved out of radius.
