"Taking delivery of a brand new outdoor swimming pool, a builder films
as a crane operator attempts to hoist the ready-made structure over the
new owner's house and into the garden." "...the man behind the lens
can be heard to exclaim "watch out for the chimney" as the delicate
operation progresses."


As near as I can tell, the rigging is just fine, and the crane is plenty
big. It appears that someone miscalculated badly when determining the
amount of counterweight to install on the crane for the lift.

I am wondering if those cranes could have some kind of an automatic
safety system that prevents tipping.

They have computers and alarms, but it's up to the operator to give the
computer the correct information and pay attention to what it's saying.
