Embodiment Construction

[0021] Reference will now be made in detail to the exemplary embodiments illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the views to refer to the same or like parts.

[0022] exist figure 1 An exemplary embodiment of a work implement (eg, machine bucket 10 ) is described in . In an exemplary embodiment, bucket 10 may be attached to a cable (not shown) configured to remove material, such as earthen material, with bucket 10 . The dragline can maneuver the dipper 10 by utilizing a lift mechanism (not shown) and a pull mechanism (not shown) controlled by an operator in a machine compartment (not shown) of the dragline control. Alternatively, bucket 10 may be attached to other types of machines known in the art, such as excavators or other earth moving machines. As another alternative, a work implement may be embodied as any device for performing the tasks assigned to the machine.

[0023] Bucket 10 may include a...

Abstract

A lip guard (26) may include a front wedge portion, an intermediate transition portion, and a rear mounting portion (52) opposite the front wedge portion. The intermediate transition portion of the lip shield (26) may be configured with at least one upwardly and rearwardly sloping transition surface (154, 151) that merges into the rear mounting portion (52) in the front edge. The at least one upwardly and rearwardly sloping transition surface may include two opposing upwardly sloping surfaces (155) extending between rearward side edges of the at least one transition surface (151 ) and extending substantially after installation The entire length of each opposing side edge of the portion (52). The upwardly sloping surfaces (155) of the two opposite sides may include outer edges (153) configured to profile smoothly upwardly sloping and outwardly convex shapes for incorporation into opposing sides of the rear mounting portion (52). in the side edge.

Description

technical field [0001] The present invention relates generally to a lip guard, and more particularly to a lip guard for a cast lip on a work implement. Background technique [0002] Earth-moving machines, such as draglines, may be used to goug or tear into soil or rock, and / or move loose material from one location to another. These machines may include buckets for digging or moving material. Buckets can experience significant wear from the abrasive and impact experienced during earthmoving applications. [0003] The bucket may include a lip including a plurality of noses protruding from a forward edge of the lip. The lip may also include flaps at opposite sides of the lip. Various wear parts may be coupled to the lip to protect the front edge of the lip. For example, the teeth may be mounted to the nose, the lip shields may be mounted between the noses, and the wing shields may be mounted to the wings. The wear part can be releasably secured to the lip by a retention sy...
