Machines That Get the Job Done: Tugboats, Backhoe Loaders, and Street Sweepers
In Machines That Get the Job Done: Tugboats, Backhoe Loaders, and Street Sweepers, presenter and motocross racer Grace Webb looks at three useful machines: a tugboat, a backhoe loader, and a road sweeper. Whether allowing us to pull a massive ship, dig a large hole with ease, or keep our streets clean, each machine serves an important purpose. 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 chair swivel around in the backhoe loader?
A: The chair swivels so that the driver can face either the front loader or the digging arm at the back, the backhoe.
Q: What protects the tugboat from damage when it’s pushing large ships?
A: Rubber bumpers and tires at the front of the tugboat protect it.
Q: Why do you think we need to clean our roads?
A: Debris, dirt, or leaves could create dangerous driving conditions.
