Okay, little buddy! Let’s talk about dumper trucks!
A dumper truck is a big truck that helps carry heavy things like sand and rocks. Imagine you have a big box of toys, and it's so heavy you need a strong friend to help you carry it. That’s what dumper trucks do!
Now here’s the fun part! This truck has a special part on the back that can lift up. It’s like when you lift your arms to reach for the sky!
When the back of the dumper truck lifts up, it makes room for the heavy stuff inside to fall out. It’s like turning your toy box upside down to let all your toys spill out! So, the truck can empty all the sand or rocks onto the ground where people need them.
So, dumper trucks are super helpful because they carry heavy things and can dump them out easily!
