Problems solved by technology

One problem encountered with some wear members constructed to ISO standards is the "skiing effect", ie, a newly installed wear member will simply skim the top of the work surface until enough of the wear member has worn away to affect proper operation surface penetration

Embodiment Construction

[0036] The present invention relates to ground engaging tool assemblies and systems, and more particularly to earth moving tool wear members, cutting bits, or cutting edges for use in various types of mining machines, earth moving machines, and construction machines. figure 1 An embodiment of a machine 50 in the form of a track-type tractor is shown that may include an embodiment of an implement wear member 100 constructed in accordance with the principles of the invention. Track-type tractors may be used to move and remove work material in a variety of surface mining or other construction applications, among other uses.

[0037] as in figure 1 As shown in , a machine 50 may include a main body 52 having a cab 54 for housing a machine operator. Machine 50 may also include an arm system 56 pivotally connected at one end to body 52 or chassis and supporting earth moving tool assembly 60 at an opposite distal end. In embodiments, implement assembly 60 may include any suitable i...

Abstract

A wear member (100) for an earth-working implement (60) including a body (101) having front, rear, top, bottom, inner side and outer side portions. The wear member (100) includes a front bottom edge (140), a front top edge (138), a front inner side edge (146), and a front outer side edge (144). The wear member (100) includes a front face (114) on the front portion (102) between the front inner side edge (146), the front outer side edge (144), the front top edge (138), and the front bottom edge (140). The wear member (100) includes a front lower cutout edge (116) and a front cutout (115). The wear member (100) includes a front lower surface (117) and includes a front cutout surface (119) defined by the front cutout (115) between the front lower cutout edge (116) and the front top edge (138). The body (101) is configured to be mounted to a mounting edge (68) of the earth-working implement (60) such that the front face (114) faces a direction away from the earth-working implement (60).

Description

technical field [0001] The present invention relates generally to ground engaging tools, and more particularly to ground engaging tools on buckets, shovels, and other work tools used with mining and construction machines. Background technique [0002] Various types of mining and construction machines, such as tractors, bulldozers, backhoes, excavators, motor graders, and mining trucks, commonly employ earthmoving shovels to move and level earth or material being excavated or loaded. During operation, earth moving shovels are frequently subjected to extreme wear from repeated contact with the highly abrasive materials encountered. Replacement of earthmoving shovels and other implements used in mining and construction machines can be costly and labor intensive. [0003] Earth-moving shovels may be equipped with ground engaging tools (GETs), such as a cutting bit, set of cutting bits, or other wear members, to help protect the shovel and other earth-moving tools from wear and ...
