Excavating adapter-to-lip connection apparatus with bottom front-accessible disconnection portion

摘要

A generally C-shaped wear member, representatively an excavating tooth adapter, is mounted on a front edge portion of an excavating bucket lip with top and bottom leg portions of the adapter respectively extending along top and bottom sides of the lip and interlocked with top and bottom ends of a base structure removably received in an opening in the lip. The top and bottom legs of the adapter are respectively and removably secured to the top and bottom ends of the base structure with top and bottom fastening structures. The bottom fastening structure has a disconnection portion which is conveniently accessible from a front bottom location on the adapter, and is useable to disconnect the bottom leg of the adapter from the base without having to reach under the lip to the rear end of the bottom adapter leg to effect such disconnection.
