A truck crane is a special kind of truck that helps lift and move heavy things, like big boxes and even cars! It has a long arm called a boom. Think of the boom as a giant arm that can stretch up and reach out to grab things.
Here’s how it works:
- Getting Ready: The crane truck drives to where it needs to help. It can go to places like construction sites or garages.
- Using the Boom: The boom can go up and down, and it can also move side to side. This way, it can reach the things that need to be lifted.
- Grabbing the Item: At the end of the boom, there is a special hook or grabber that catches onto the heavy item.
- Lifting: Once the boom is holding the item, the crane can lift it high into the air and move it to a different spot. It’s like picking something up with your own arms but much stronger!
- Putting It Down: After moving it to the right place, the crane gently lowers the item down, just like when you put your toys back on a shelf.
So remember, the truck crane uses its boom to lift and move heavy things around, making it very helpful for many jobs!
