Cast contact pads
Abstract:
A contact pad is provided having a load-engaging front surface and an oppositely-facing rear surface, preferably comprising a cast metal contact pad having at least one depression adjacent to the rear surface and a tile embedded within the depression such that the tile has an exposed surface, and a wear element on the exposed surface. A method for manufacturing a contact pad having a load-engaging front surface and an oppositely-facing rear surface preferably includes the steps of embedding a mild steel tile within a contact pad casting pattern such that, once embedded, the embedded tile has an exposed weldable surface, casting the contact pad from ductile cast iron and applying a wear element on the weldable surface.
