Big Digs With the Backhoe Loader!
In Big Dig With the Backhoe Loader!, presenter and motorbike racer Grace Webb takes us on a tour of a powerful backhoe loader, a machine with not one, but two digging arms! The backhoe at the back is perfect for digging huge holes, while the loader up front scoops and fills them back up. This video is excerpted from BBC’s Grace’s Amazing Machines, a children’s show that introduces kids to some of the biggest, fastest, and most amazing machines in the world.
Lesson Express
Q: Why does the backhoe loader have such big, ridged wheels?
A: The large, ridged wheels help it move over bumpy ground on construction sites, making sure it can dig and load on uneven terrain.
Q: How might using the joysticks to control the backhoe be similar to playing a video game?
A: The joysticks control the backhoe’s movements, like lifting and scooping, similar to how a video game controller lets you control actions on the screen.
Q: Why is it important for the backhoe and loader to work together on a project?
A: The backhoe can dig a hole, and then the loader can move or refill the dirt, making it possible to do two jobs with one machine and save time.
