Why Don't Billion Pound Cranes Tip Over

Описание: A steel arm hundreds of feet long.
Loads weighing tens—or even hundreds—of tons.
All balanced on a tower that looks far too small.

Every instinct says it should fall over.

But it doesn’t.

In this video, we break down the hidden physics and engineering that keep tower cranes and mega-cranes standing tall. From massive underground foundations to perfectly calculated counterweights, cranes survive enormous tipping forces by mastering one simple idea: moment.

You’ll learn:
Why a crane’s foundation is as important as the crane itself
How counterweights create perfect balance using leverage
What “moment” really means—and why it matters
How wind and height threaten crane stability
Why cranes are tied into buildings as they climb
How Load Moment Indicators prevent catastrophic mistakes
How modern cranes use moving counterweights to increase lifting power

These machines don’t fight gravity.
They negotiate with it—using physics with ruthless precision.
