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.

Claims

1. A liner for a load carrying work machine body, comprising:

a first wear resistant plate section having a plurality of laterally extending projections defining a plurality of laterally opening recesses therebetween; and

a second wear resistant plate section having a plurality of laterally extending projections defining a plurality of laterally opening recesses therebetween, said first and second plate sections are located adjacent to one another such that a plurality of openings are defined in said liner.

2. The liner of claim 1 wherein said openings cause load material ejected across said liner to tumble rather than slide across said top surface of said plate structure.

3. The liner of claim 2 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from steel.

4. The liner of claim 2 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from metal.

5. The liner of claim 2 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from a non-metallic material.

6. The liner of claim 2 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from a single homogeneous material.

7. A liner for a load carrying work machine body, comprising:

a first wear resistant plate section having a first set of lateral projections that define a first set of laterally-opening recesses; and

a second wear resistant plate section having a second set of projections that define a second set of laterally-opening recesses, said first and second plate section sections are located adjacent to one another such that the first set of projections interfit in respective ones of the second set of recesses to thereby define a segmented plate structure.

8. The liner of claim 7 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from steel.

9. The liner of claim 7 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from metal.

10. The liner of claim 7 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from a non-metallic material.

11. The liner of claim 7 wherein at least one of said first wear resistant plate and said second wear resistant plate is manufactured from a single homogeneous material.
