Abstract
Liner plates of mild steel layered over with chromium carbide are provided with a bi-planar spacer clip also acting as a lifting eye on the top surfaces thereof and fasteners such as bolts or studs extending from the exposed planar surface of the mild steel layer. A chain and hook arrangement is used to deliver and locate each liner plate adjacent a wall upon which the liner plates are to be mounted in vertically stacked relationship. The clips serve as spacers between vertically stacked liner plates and the fasteners extend through pre-formed holes in the wall of the delivery structure. The clips have a notched base portion which receives a weld bead running along the top exposed edge of only the mild steel layer. The clips are left in place after installation and are gradually worn away by ore traveling through the delivery structure.
