Wear assembly for excavating machines

Abstract

A wear member includes a pair of legs defining a slot straddles the digging edge of a piece of excavating equipment. In one construction, the slot is formed at its front end with a pair of inclined surfaces and a laterally extending ridge that is fit within a complementary channel on the digging edge. A lock is received within an opening in the wear member to releasably secure the wear member to the digging edge.

Description

technical field [0001] This invention relates to a wear resistant assembly for use along the digging edge of an excavator. Background technique [0002] Excavating equipment of all types and sizes includes various wear parts to protect the front digging edge from damage and wear, which are often subjected to highly abrasive materials and under severe conditions. use. In order to withstand the rigors of digging, the wear resistant parts must be positively retained on the digging equipment so as not to be lost while in use. However, due to the harsh environment, the parts often wear out and must be replaced. [0003] Various means have been developed, with varying degrees of success, for attaching the wear resistant part and allowing for easy replacement of the part as it wears out, in terms of positively retaining the part while excavating. For example, wear resistant parts are often welded to the digging edge to prevent loss during use. While welding does hold the part t...
