Q:The most dangerous among crane accidents are:?
Dangerous to whom and exactly what does overturns mean? Operators are most likely to be killed when a tower crane breaks (is this an overturn?) because the operator is several hundred feet up in the air in the cab. Hitting power lines can be risky to the operator if dumb but staying in the cab is likely to be safe (stepping out may kill in touching ground) Overturning a ground based crane is going to hurt someone in the area much of the time.
Q:Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace...?
Apparently that IS what they were called. Who knew? I would have guessed something a little more poetic like Dragon's Tail because it's long and straight, swings on a pivot and frequently has notches along to top for latching the bails of cooking pots and the like. Crane sounds so... so... ordinary.

Q:How do they get the construction cranes up the sides of buildings as they increase the height of the building?
Sometimes the structure of the crane is built onto using the crane itself, building itself into a box. Then the crane lifts itself to the higher level. This can be done many times.
Q:Climbing process of an internal climbing tower crane
