Bulk container trucks and tilt trucks are large wheeled containers that are used to move bulk materials from one place to another. Tilt trucks have a slanted wall that allows the trucks' contents to fall out when the trucks are tipped forward, which speeds unloading compared to non-tiltable bulk container trucks. Hopper trucks have tapered ends that minimize the distance materials need to be lifted to load them onto the trucks. Cube trucks and box trucks have containers with tall, impact-resistant, rigid walls. Basket trucks have containers with soft fabric walls.
