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.

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

A liner for a work machine body, such as the body of an off-highway truck, protects the body from wear. The liner has a plate with openings through the plate arranged in a preselected pattern. The plate is of a size to fit a particular portion of the body and is typically removably fastened to the body. The plate has raised strips of abrasion-resistant cladding, such as chromium carbide, bonded to the top surface thereof. The raised strips cause material to tumble, instead of to slide, when being removed from the truck. The tumbling action reduces wear on the liner.

A guarding and clamping device wherein a plurality of control lines are held in position by resilient blocks on a support member of a work machine. The control lines are also protected and maintained in an ordered arrangement by cover guard.
