Abstract

A locking assembly for retaining a wear member to excavating equipment has a locking element that is received into an opening in the assembly and is movable about a pivot axis in the opening between a hold position and a release position. The locking element has an outer edge that is generally opposite the pivot axis that opposes a base surface of the opening when the locking element is in the hold position. The outer edge is configured to pull away from the base surface when the locking element is rotated from the hold position toward the release position.
