The Liverpool tower crane that collapsed is being removed.
It's a good showing of what it takes to remove these
cranes after collapse. They have a self erector to suspend
the workers cutting the crane apart. There is a 500 ton
crane assisting the 800 ton crane. Clean up of this
magnitude can easily approach a million dollars. I was
involved with the clean up for the Belleve crane collapse
and the cutting apart of the crane and it is a long drawn
out process to figure out weights, closest center of gravity
for rigging, and methods of cutting that will prevent the
shock loading on the crane. It's dangerous work for certain.
