Atlanta tower crane mishap

News is coming in of an unstable tower crane in the centre of Atlanta, Georgia. It looks as though something went wrong while the crane - a Terex hammer head - was being climbed down/dismantled at the end of its contract. The emergency services have evacuated the area and are waiting on the arrival of a two mobile cranes along with additional tower crane erectors.

If you don't know what you're talking about it is better not to comment.
One needs to know the instructions of the manufacturer given by manual and training.
climbing down a crane is not an easy job, and a hard job. Crane erectors are special
people and very reponsable. Unfortunately something went wrong here, I am happy to see the crane still stands and nobody is injured. But keep you comments till after the investigation results. We all (the industry) can only learn from misshaps to prevent other accidents.

No requirement to remove ballast up or down. Another case of jumping the gun in the good old USA.

Atlanta fire department have released this statement (copy and paste)
Atlanta fire spokesman Sgt. Cortez Stafford said a mechanical failure with one of the crane’s hydraulic cylinders caused the crane to lean.

If it had too much back ballast then ghat would have suggested that one piece of ballast should have been lifted off before the climbing down process. If a crane could have lifted the ballast off then it could have disassembled the whole crane, removing the need for the climbing operation.... so that sounds a tad implausible to me... am no expert but it doesn't sound right....

There is too much back ballast still on the crane for that configuration, its surprising it hadn't missed the rearward guides due to deflection on the first few sections.
