Rock box liner for a floor of a dump truck body

摘要

A rock box liner for a floor of a dump truck body includes a plurality of bins coupled to the floor. Each bin has an opening for receiving an amount of payload material from a payload that is deposited within or dumped from the body. When payload material from the payload is deposited within the bins, a portion of the payload material extends upward and outward from the openings of the bins to thereby create a supplemental surface upon which a substantial portion of the payload moves across when dumped. The supplemental surface shields the floor of the body from frictional wear due to loading and dumping of payloads and thus extends the body's operational life.
