How Giant Steel Cables Are Made In Massive Production Line | Over 10,000 Feet In Length

Описание: How Steel Cables Are Made – Strong Enough to Hold the Brooklyn Bridge | THE MAKING

The Brooklyn Bridge has carried millions of people for more than 140 years. Every day, 120,000 cars cross safely — all thanks to one thing: 14,000 miles of steel cables holding the bridge together. That’s enough cable to stretch halfway around the planet.

But how are steel cables actually made strong enough to support a bridge weighing 14,680 tons? In this documentary, we follow the journey of steel cables from raw iron ore to twisted strands of steel wire that can hold up skyscrapers, oil rigs, wind turbines, and one of the most iconic bridges in the world.

Born out of desperation in the 1830s when miners needed something stronger than hemp ropes, steel cable quickly became one of the most important inventions in engineering history. Today, factories produce over 10 million tons every year — the hidden backbone of modern civilization.
