Transcription: Dump trucks are used to carry materials from, to and around the construction site. They have large metal boxes called beds which are filled by the loader. Off the road dump trucks have gigantic tires and are used to move huge amounts of material around the construction site. To empty the load, the driver raises one end of the truck bed in the air, then gravity makes the material slide out of the truck. This over the road dump truck is delivered delivering the soil that will be leveled to create the roadbed.
