摘要

A truck body designed for transporting hard rock mined ore. The truck body includes a body floor having a first material forming a floor structure and a liner structure including a second material covering at least a portion of the floor structure. The second material has a hardness that is greater than a hardness of the first material and prevents wear of the truck body floor by the hard rock ore. The truck body includes a front wall and two opposing body sidewalls that taper outwardly from front to rear of the truck body such that a width between the body sidewalls at a rear of the truck body is at least 10% greater than a width at the front of the truck body. The outward tapering of the body sidewalls promotes movement of the load away from the body sidewalls as the load is released from the truck body.
