A wear component for use on, for instance, an excavator formed by a shell formed from a tough metal such as carbon steel and an inner body formed from an abrasion resistant metal such as a chromium white iron. The shell includes cross portions extending through the inner body, the cross portions being made of the tough metal. This has the effect of strengthening the overall toughness of the wear component, while retaining desirable abrasion resistance.

Wear resistant component

An attachment system for connecting a first member such as a lip plate of a mechanical digging device to a second member such as a ground engaging tool. The first member has a lug attached thereto, and the second member has a recess which is located about the lug A stabilizing member is located within a slot in the recess. A clamping member is between the lug and the stabilizing member, and includes a resilient portion such as a compression spring. A compressive force supplied to the resilient portion restricts the movement of the second member relative to the lug.
