Yes it was.
The way they lift the load.
A crane is a vehicle used to lift things usually with a hook.
Birds do not lift weights.
The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib. The closer the load is positioned to the mast (center of rotation), the more weight the crane can lift safely.
A crane can lift heavy things higher than people can.
To lift things.
Up to one ton, apparently..
The record for the heaviest crane lift belongs to the "Taisun" crane in China, which lifted a 20,133 metric ton (44.385 million pounds) jacket in 2014.
That depends on the specifications of the crane. The largest crane in the world is capable of lifting 20,000 Metric Tons (tonnes).
This is one of the mysteries of the universe. The answer was revealed to me once in Shanghai. A crane "grows" or gets taller as needed as the building under construction is built. the top section of the crane as a lift built in. The crane hauls a new section, like a section of scaffolding, up to the top and sets in place. I'm told that a crane is often anchored in place in the base of the elevator shaft, so when the building is complete, they lift the crane out section by section, leaving the very base in the elevator shaft permanently. Or at least that's the way I understand it to happen.
it is used to lift stuff
Many insects can lift objects of huge weight, proportionate to their own size. An ant, for example, can lift 5 times its own body weight.
