Excavators are big machines that look like giant robots! They can help us dig in the dirt and move things around. Let’s see how they move, step by step:
- Big Wheels: Excavators have big wheels or tracks, like a tank! These help them roll over the ground with ease.
- Turning Around: Sometimes, they need to turn. The middle part can spin around, like when you are turning in a circle!
- Using Arms: Excavators have long arms that move up and down. They can grab dirt and stones and put them somewhere else!
- Driving Forward: When the driver wants to go, they push buttons or pull levers. This tells the excavator to push its wheels forward.
- Stop and Go: The driver can make the excavator stop! It's like when you play 'freeze' during a game.
So, excavators are like amazing toys that help us with work by moving around, digging, and lifting! Isn't that cool?
