Why don't Cranes Fall Over?🏗️| Curious Questions

#why #curious #kids #question #education

A crane🏗️can lift and move heavy things and set them down again in a different place. To lift the loads, cranes🏗️usually have a winch. Cranes are used to load and unload ships. But also trains and trucks. There are many different types of cranes🏗️for this purpose. To move containers in the port, there are huge bridge cranes. Some trucks also have small cranes on their loading area. The tall, fixed cranes🏗️ you see on construction sites are tower cranes. They often reach far into the sky. To prevent them from falling over, they have a stable concrete foundation at the bottom. This keeps them firmly on the ground. They also have a weight at the top of the short end of their arm. These concrete plates keep the crane🏗️balanced when it is pulling up a heavy load. The tower of the crane is very stable. If it should ever be very windy, it doesn't matter. The wind then simply blows through the lattice. This is because the lattices offer the wind only a small surface to attack. In addition, the crane🏗️arm is movable. It turns with the wind like a weather vane. And that's another reason why the crane always stays straight.

In a nutshell: Because they are kept in balance by heavy plates and are movable at the same time, even the highest cranes🏗️do not fall over.

Hello, I have a question that I couldn't find the answer. How does the dead weight on the other side balances the jib on the ever moving moments caused by the load???? No videos explains this important working principle. I felt very frustrated.
