ELI5: Explain Like I'm 5

Dump trailer

A dump trailer is like a big wagon that you can put things in, like dirt or rocks or wood. But instead of just pulling it around, a dump trailer can tilt up and dump out all the things inside. It's kind of like when you turn over a bucket to dump out the sand you just played with on the beach. The dump trailer has a special device that lifts up one end and tilts it until everything inside falls out. This is really helpful when you need to move a lot of heavy things from one place to another quickly, like when you're helping clean up a job site or moving things around a farm or garden.
