1. A method for minimizing relative movement between a liner plate and an interface surface of a load-bearing portion of mobile earth-moving machinery, the liner plate comprising a first opening, a second opening, and a grout strip, the grout strip being disposed along a perimeter of the liner plate

1. A method for minimizing relative movement between a liner plate and an interface surface of a load-bearing portion of mobile earth-moving machinery, the liner plate comprising a first opening, a second opening, and a grout strip, the grout strip being disposed along a perimeter of the liner plate, the method comprising: a) welding the liner plate at the grout strip to the interface surface;b) filling a space defined by the grout strip, the liner plate, and the interface surface with grout, the filling being performed via the first opening while air from the space exits through the second opening; andc) allowing the grout to harden,wherein a hardening of the grout enables the liner plate and the load-bearing portion to form a single structure to distribute load within the single structure. 2. The method of claim 1, further including: covering the first and second openings. 3. The method of claim 1, wherein the grout fully covers the interface surface. 4. The method of claim 1, further including coating the interface surface with lubricant to ease removal of the liner plate from the interface surface. 5. The method of claim 1, wherein the welding comprises seam welding. 6. A liner plate for mounting on an interface surface of a load-bearing portion of mobile earth-moving machinery, the plate comprising: a) at least two openings; andb) at least one grout strip along a perimeter of the liner plate,wherein the liner plate is configured to be welded at the interface surface at the at least one grout strip to create a space defined by the grout strip, the liner plate, and the interface surface,wherein a first opening of the at least two openings is configured for passage of grout to fill up the space and a second opening of the at least two openings is configured for passage of air, andwherein the liner plate is configured to function as a replaceable sacrificial damage item to prevent the interface surface from getting damaged while also preventing pre-mature damage of the liner plate itself due to weld-cracks and localized deformation by minimizing relative movement between the liner plate and the interface surface. 7. The plate of claim 6, wherein the at least one grout strip is fabricated from mild steel. 8. The plate of claim 6, wherein the at least two openings each include a securing mechanism. 9. The plate of claim 8, wherein each securing mechanism is sized to allow the placement of a cover in each of the at least two openings. 10. The plate of claim 8, wherein the securing mechanism is configured for removable attachment of conduits to the liner plate. 11. The plate of claim 7, wherein the at least one grout strip is 3 mm thick and 23 mm wide. 12. A method for minimizing relative movement between a liner plate and an interface surface of a load-bearing portion of mobile earth-moving machinery, the liner plate comprising a first opening, a second opening, and a grout strip, the grout strip being disposed along a perimeter of the liner plate, the method comprising: a) coating the interface surface with a lubricant;b) welding the liner plate at the grout strip to the interface surface;c) filling a space defined by the grout strip, the liner plate, and the interface surface with grout, the filling being performed through the first opening while air from the space exits through the second opening; andd) allowing the grout to harden,wherein a hardening of the grout enables the liner plate and the load-bearing portion to form a single structure that distributes load within the single structure, andwherein coating the interface surface with the lubricant eases removal of the liner plate from the interface surface. 13. The method of claim 12, further comprising removably attaching a first conduit to a securing mechanism of the first opening to channel grout to fill the space. 14. The method of claim 12, further comprising removably attaching a second conduit to a securing mechanism of the second opening to allow air to exit from the space through the second conduit and to avoid voids in the grout. 15. The method of claim 13, further comprising removing the first conduit from the securing mechanism after the space is filled and coupling a hard facing over the first opening. 16. The method of claim 14, further comprising removing the second conduit from the securing mechanism after the space is filled and coupling a hard facing over the second opening. 17. The method of claim 12, wherein the grout fully covers the interface surface. 18. The method of claim 12, wherein coupling comprises seam welding. 19. The method of claim 12, wherein the grout strip is 3 mm thick and 23 mm wide. 20. The method of claim 12, wherein the grout strip comprises mild steel.
