Embodiment Construction

[0025] figure 1 An exemplary work tool 10 for a machine (not shown) is illustrated. The work tool 10 may implement any device for performing the tasks assigned to the machine. For example, the work tool 10 may be a bucket ( figure 1 Shown in), blades, shovels, crushers, grabs, rippers, or any other material moving devices known in the art. The work tool 10 may include side walls 12, 14 and a main wall 16, which may form the bottom of the work tool 10. The main wall 16 may extend from the side wall 12 to the side wall 14. The main wall 16 of the work tool 10 may also include an edge 18 extending between the side walls 12, 14 (see figure 2 ). The edge 18 can be detached from the work tool 10 or it can be a fixed part of the work tool 10.

[0026] The work tool 10 may include a plurality of shields 22 (or wear members) attached to the edge 18. Each shield 22 may be configured to protect the edge 18 from wear and abrasion by reducing or preventing contact of the exposed portion ...

Abstract

A shroud (22) for a work tool (10) is disclosed. The shroud may have a tip portion (40). The tip portion may have a tip (44) extending from a shroud proximal end (70) to a tip end (74) disposed between the shroud proximal end and a shroud distal end (72). The tip portion may further have an upper leg (46) extending from the tip end to an upper leg distal end (76). The tip portion may also have a lower leg (48) extending from the tip end to a lower leg distal end (78). The lower leg may be spaced apart from the upper leg to form an opening (50) between the upper leg and the lower leg. The shroud may have an attachment portion (42) attached to the upper leg. The attachment portion may extend from adjacent the tip end to the shroud distal end.

Description

Technical field [0001] The present invention relates generally to a shield retention system, and more specifically to a shield retention system for work tools. Background technique [0002] Earth-moving machines such as excavators, forklifts, and wheel loaders include ground-joining work tools that join and / or move various soil materials. These work tools typically have one or more cutting tools or tooth assemblies that are mounted to the edge of the work tool (e.g., to the lip of a bucket). The exposed part of the edge of the work tool between adjacent tooth components is in contact with the ground or earthy materials, and is subject to extreme wear and impact that cause them to wear. In order to prolong the service life of the work tool, a wear-resistant member or shield is attached to the work tool between adjacent tooth components to protect the exposed part of the edge of the work tool. [0003] Although the wear-resistant member protects the edges of the work tool, the wear...
