Title: Liner for a work machine body and method for manufacturing the same

Abstract: A liner for a high-wear portion of a work machine body, such as a dump truck body, is formed by separating a unitary plate of wear material, such as steel, into separate plate sections. The plate sections are formed such that confronting plate sections have portions that interfit with each other. Gaps or voids are left between the interfitting portions to define openings the liner from the top surface to the bottom surface thereof. The openings cause material ejected across the liner to tumble rather than slide, thereby reducing abrasive wear. By separating the plate and forming the liner in this manner, no scrap material is created, which reduces cost compared to known design. In addition, liners having a variety of different dimensions can be created from the same plate sections by varying the relative spacing between adjacent plate sections.
