A bucket for an underground loading machine includes an opened bucket front and a concaved bucket back. To provide abrasive wear resistance, the bucket includes a paddle plate joined to the bucket underside of the bucket floor. The paddle plate can have a trumpet-shape tapering from flared forward edge to a plate tail disposed toward the concaved bucket back. The bucket may be configured as a wedge bottomed bucket and include a plurality of spacer wedges disposed between and spacing apart the bucket underside and the paddle plate.

A support assembly for ground engaging tools comprises a tool (106) operatively connected to a working edge (116) of a work implement (100); a support member (134) operatively connected to the working edge (116) separately from the tool a predetermined distance away (164) from the tool (106) along the sweep direction (S, S′); wherein the support member (134) and tool (106) are operatively associated with each other and are configured to provide a load path (128) between the tool (106) and the support member (134) along at least a portion of the sweep direction (S, S′).

A kit for supplying components for a support assembly for ground engaging tools comprising a shroud protector for use with the support assembly that is configured to be attached to a work implement using a retaining mechanism, a tool adapter and a shroud insert that includes a resilient member that is configured to engage the reinforcement surface of a tool adapter, wherein the shroud insert is disposed between the work implement and the shroud protector.

A support member for use with a support assembly for ground engaging tools comprises a structural member; and a resilient member that includes a base, and a contact surface, and wherein the structural member defines a direction of assembly and the resilient member defines a length and a width that are perpendicular to each other and to the direction of assembly, wherein the length exceeds the width and the base defines a centerline that is parallel to the length, and the contact face defines a centerline that is parallel to the length.

A wear resistant component includes a matrix portion made of metal, and a core that is embedded in the matrix portion and is higher in hardness than the matrix portion. The core has a shape that follows a shape of at least a portion of a surface of the matrix portion.

A wear member assembly may include a nose attachable to a bucket lip. The nose may include a rear portion having a first set of substantially planar surfaces including a first, second, and third subset of surfaces. The third subset of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The nose may also include a forward portion positioned forwardly adjacent to the rear portion, the forward portion having a second set of substantially planar surfaces including a fourth, fifth, and sixth subset of surfaces. The sixth set of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The wear member assembly may also include a wear member having a cavity comprising rear and forward bearing surfaces corresponding to the third and sixth subset of surfaces.

A fastener includes an elongated shaft having a head at the end, the head comprising a lock fin extending radially outward from the shaft. The head includes an engagement cavity. The fastener further includes a cap having an engagement protrusion for insertion into the engagement cavity of the cap such that rotation of the cap causes corresponding rotation of the head, the cap further comprising a contact portion having a plurality of radially outward facing planar surfaces. The fastener further includes a rotation resisting element having inward facing planar surfaces that fit with the radially outward facing planar surfaces of the contact portion, the rotation resisting element further including an interference feature extending radially outward, the rotation resisting element being resilient so as to allow but resist rotation of the cap with respect to the rotation resisting element.

A retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.

An articulated lock for securing a wear member to earth-working equipment includes a plurality of bodies interconnected for pivotal movement between an extended orientation with the bodies aligned and a retracted orientation with the bodies folded. The lock in the extended orientation can engage an opening of the wear member at an inner hold position to secure the wear member to the earth-working equipment or an outer release position. In the folded orientation the lock disengages from the opening of the wear member. Each body has a slot and a tab and, in the extended orientation, the tab of each body is received in the slot of the other body to limit separation of the bodies.

A lug member includes a slide platform defining a slide groove that further defines a sliding direction, a first end that is disposed along the sliding direction, and a second end that is disposed along the sliding direction. A spacer engaging projection extends downwardly from the slide platform.
