Have you ever wondered how much a human can lift? The strongest woman in the world can lift 387.5 kilograms - that's over 3.5 times her own body weight. And the strongest man? Yeah, he can lift 425 kilograms, 2.3 times his bodyweight.
However, these ridiculously strong people don't match up to the animal kingdom. A gorilla weighs 220 kilograms and can lift 10 times its body weight, at a grand total of 2,200 kilograms.
Compare the animal world to the mechanical world - A forklift can lift up to 100 tons. An an airplane? Forget about it. A Antonov AN-225 Mriya weighs 285,763 kilograms and can lift off weighing up to 580,598 kilograms.
