An excavator is a big machine that helps to dig and move dirt, rocks, and other heavy things. Think of it like a giant robot with a long arm and a big scoop on the end, like a shovel!
Here’s how it works:
- Big Arm: The excavator has a long arm that can reach out and move things around.
- Digging: The scoop at the end of the arm can dig deep into the ground to pull up dirt or rocks.
- Moving: Once it has a scoop of dirt, it can lift it and move it to a new spot.
- Building: Excavators are often used in construction to help build roads, homes, and other large projects.
So next time you see an excavator working, remember that it’s a special machine that helps us dig and move big piles of stuff!
