Embodiment Construction

[0046] The present invention relates to GET assemblies and systems for various types of mining and construction machinery. figure 1 An embodiment of a machine 50 in the form of a hydraulic shovel is shown that may incorporate an embodiment of a GET assembly 70 constructed in accordance with the principles of the present invention. Among other uses, hydraulic shovels may be used to load overburden and ore onto haul trucks during the mining process for various surface mining applications.

[0047] Such as figure 1 As shown, machine 50 may include a main body 52 having a cab 54 housing a machine operator. The machine may also include an arm system 56 pivotally connected to the main body 52 at one end and supporting an implement 60 at the other opposite distal end. In an embodiment, implement 60 may be any suitable implement, such as a bucket, flip bucket, blade, or any other type of suitable device that may be used with a GET. A control system may be housed in cab 54, which ma...

Abstract

The present invention provides a ground engaging tip including a ground engaging portion and a coupling portion. The coupling portion includes an interior surface, sidewalls, and interlocking tabs. The inner surface defines a coupler pocket and has a bottom wall. The side walls and the bottom wall define the coupler pocket. The interlocking tab has a base end and a proximal end. The bottom end of the interlocking tab abuts the side wall, and the interlocking tab extends from the bottom end to the proximal end. The side walls define retention apertures. The ratio of the first distance measured from the center of the retention aperture to the bottom wall to the second longitudinal distance measured from the center of the retention aperture to the proximal end is about 3:2 or less .

Description

technical field [0001] The present invention relates generally to ground engaging tools and, more particularly, to ground engaging tools on buckets, scrapers and other work tools used in mining and construction machinery. Background technique [0002] Different types of mining and construction machines, such as backhoes, wheel loaders, hydraulic shovels, cable shovels, bucket wheels, and draglines, typically employ buckets to dig and remove soil being worked on or Excavated or loaded material. Buckets often experience extreme wear from loading forces and highly abrasive materials encountered during operation. The replacement of large buckets and other implements used in mining and construction machinery can be very expensive and laborious. [0003] Buckets can be equipped with a Ground Engaging Tool (GET) or a set of GETs to help protect the bucket and other soil working tools from wear and tear. Typically, a GET can be in the form of a tooth, edge guard, tip, or other re...
