Hey there! An excavator is a big, strong machine that helps people dig in the ground. It looks kind of like a giant robot with a long arm and a big scoop on the end, like a shovel.
Here’s how it works:
- The Arm: The long arm of the excavator stretches out really far so it can reach deep into the ground.
- The Scoop: At the end of the arm, there’s a scoop that can grab dirt, rocks, or even big pieces of old buildings.
- Moving: The excavator can spin around in circles and move forward or backward to go wherever it needs to dig!
- Digging: When the scoop goes down into the ground, it digs up dirt and lifts it out. It’s like using a big shovel to make a hole!
- Dumping: Once it has a scoop full of dirt, the excavator can lift the scoop high up and dump the dirt in a new spot.
Excavators are super helpful on construction sites because they make it easier and faster to build things like roads, houses, and parks!
