A base edge includes a plurality of center notches and a first and a second end notches that all include the same configuration, defining a notch depth along direction of assembly, a straight middle portion straddled laterally by a first arcuate corner portion and a second arcuate corner portion, the straight middle portion defining a lateral straight middle portion width, and the notch depth ranges from 0.1 multiplied by the lateral straight middle portion width to 0.5 multiplied by the lateral straight middle portion width.

The first and the second legs and the throat portion of an adapter include an upper surface and a lower surface that at least partially define a slot, and a clearance void disposed at the closed end of the slot. A ratio of the clearance void width to the clearance void height ranges from 2.0 to 3.0.

An adapter cover includes a shell body including an exterior surface and an interior surface. A front face portion defines a thru-hole, a top leg extending horizontally from the front face portion and defining an adapter cover key on the interior surface. A top leg side portion defining a concave arcuate portion extending rearward from the front face portion, a convex arcuate portion extending horizontally from the concave arcuate portion, and terminating in a vertical rear surface. A bottom leg extending horizontally from the front face portion.

An adapter includes a first leg, a second leg, and a throat portion that define a slot defining a direction of assembly onto a work implement assembly, a lateral direction that is perpendicular to the direction of assembly, and a vertical direction that is perpendicular to the direction of assembly and the lateral direction. The throat portion further includes a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction. The first throat side surface defines a first adapter cover receiving recess.

A lifting connector to facilitate the lifting of wear parts used on earthmoving equipment is mechanically secured to a hole in the wear part. The wear part has a latching formation to maintain the head of the connector in a preferred orientation so that it is in the proper service position for connecting the lifting connector to a lifting device. The wear part can be safely maneuvered onto and off of the earthmoving equipment while secured to the lifting device.

A wear member comprising: an upper leg having a ground engaging surface on an outer side thereof and a mounting surface on an inner side thereof, and a lower leg spaced apart from the upper leg and also having a ground engaging surface on an outer side thereof and a mounting surface on an inner side thereof, the mounting surfaces defining a mounting cavity therebetween and the legs meeting at a front portion, the upper leg defining (i) a lock aperture therein, (ii) a rear edge, and (iii) a lifting feature located adjacent to and between the lock aperture and the rear edge; the lifting feature defining (a) a front surface lower than the upper leg ground engaging surface and being inclined relative thereto, (b) a lower support surface opposite the front surface, and (c) a rear engaging surface extending between the front surface and the lower support surface and being recessed relative to the rear edge; wherein the front surface, lower support surface, and rear engaging surface provide a narrowed portion around which a lifting device may be located for relocating the wear member.

A process and tool for installing and removing various kinds of wear parts used with earth working equipment. The process and tool allows the operator to remove and install the wear parts at a safe distance so that the operator is physically remote from the potential risks of the removal and installation process. The tool may be manually operated via an operator or the tool may be a semi-automated or fully automated.

A handling system for handling ground-engaging wear parts used on earth working equipment includes handling tools to remove and handle wear parts from equipment and/or to install new wear parts. The tools can include a torque or other tool to engage and/or disengage a lock retained by the wear member. The handling system allows an operator maintain a distance from heavy parts being removed or installed, reducing the risk of injury.

An adapter cover includes a shell body including an exterior surface, an interior surface, and defining a vertical direction, a horizontal direction, and a vertical plane, a front face portion defining a thru-hole, a top leg extending horizontally from the front face portion and defining an adapter key receiving recess on the interior surface and a top leg side portion defining a concave arcuate portion extending rearward from the front face portion, a convex arcuate portion extending horizontally from the concave arcuate portion, terminating in a vertical rear surface, and a bottom leg extending horizontally from the front face portion.
