Excavator

The excavator was my favorite when I was a kid. I like to watch the excavator under construction on the side of the road and appreciate its dynamic dynamics. It is like a huge robot arm. The excavator is really cool!

This is a movable excavator model. Just turn the handle to simulate the dynamics of the excavator. If you connect two or more excavators side by side, they can operate synchronously and make a circular excavation action, which is very interesting!
