Wear plates are assumed not to take structural load. Wear plates overlap the main bucket structure to protect from wear.

In some forms, a removable basket portion of the basket body comprises a plurality of plates which may include the lower shell plate 23, upper shell plate 22, side wall plate 25 and wing plates 26. One or more or a selection of plates may be removable either through cutting or otherwise removing the plates from the basket body. The removable plates or removable cast sections may form the removable basket portion of the basket body. Cuts for removing the removable portion of the basket can be made at welded joints or through sections of the plate, or otherwise as needed.

As shown in the Figs., the basket 11 is formed by the plurality of plates and no separate frame is needed to support the basket. The plates may be formed of structural steel. The plates themselves work together to form the basket and provide sufficient support and strength to maintain the basket while removing the removable portion of the basket. A frame is not required. The plates are joined to one another by welding or alternative joining process. In some welded forms, full penetration butt welds are used in high stress areas. For example, full penetration butt welds are used at the joint between the basket and lip members or cast lip. All structural plates work together to provide strength and stiffness to the bucket. In some forms the structural plates are connected to one another directly and form the whole interior cavity of the basket body 11.

The engagement beam 12 of the ground engaging member comprises a beam body 40 and a plurality of lugs 41 extending from the engagement beam. An access portal 45 is located at one or both ends of the engagement beam.

In some forms the engagement beam 12 (which may be cast) may be used to house or mount sensors, power sources, communication equipment and data acquisition devices, etc. In some forms, the engagement beam may house wireless communication devices so that cables would not need to be run along the boom of the excavator to any of the sensors or equipment on the bucket.

Referring now to FIGS. 4 through 10, disclosed is an engagement beam 12 comprising a beam body 40, a plurality of lugs 41 attached thereto. Each lug includes a front and rear bore to allow the lugs 41 to be attached to the machine (e.g., an excavator machine. The engagement beam 12 may also comprise one or more end portions 42. In the illustrated embodiment, the beam body 40 extends between two end portions 42. In some forms the engagement beam 12 may be removable or replaceable from the basket body as shown in FIG. 4.

The engagement beam 12 extends between the side walls 15 to span the distance between the side walls 15. The beam body 40 extends between two end portions 42. Each end portion 42 forms the end of the engagement beam 12 and also forms part of the side wall 15. Along with the side edges 19 of side walls and the forward lower edge 20, the end portions 42 and the beam body 40 define the opening to the basket interior 18. The end portion 42 is joined to the beam body 40 and the side walls 15 by welding. In some forms, the end portion is integrally cast with the beam body.

Each end portion 42 respectively forms the corner between the beam body 40 and the side wall. The end portion 42 includes a forward side wall portion 44 extending towards the forward lower edge 20 in line with the side wall and a similar thickness of the side edge 19 (and in some embodiments the wing plate 26) of the side wall 15.

The end portion 42 also includes a rear side wall portion 46 extending in line with the side wall plate 25 towards the upper shell plate 22 of the basket body. The profile of the rear wall portion 50 is an s-shaped profile. An arcuate transition region joins the forward side wall portion 44 and the rear side wall portion 46. The rear side wall portion 50 includes one or more shoulders 47 having an arcuate region which forms part of the side wall 15. The shoulder 47 provides a structural feature to guide to assist in positioning the end portion 42 relative to the side wall 15. The shoulder 47 also limits the movement of the end portion 42 relative to the side wall 15 prior to joining the components.

Further, the end portion 42 also includes a beam portion 48 extending in the direction of the beam body 40. The beam portion 48 is substantially the same size and shape as the beam body 40.

The inner transition region between the beam portion 48 and the forward side wall portion 44 meet at an arcuate transition region 49. The profile of the arcuate transition region 49 may include a radius or radii of curvature. The arcuate transition region provides a smooth transition between the beam portion 48 and the forward/rear side wall portions 44/50 so as to enhance the strength of the engagement beam, the components defining the opening to the basket interior, and the overall bucket 10. The arcuate transition regions are an alternative to the surfaces of the components meeting at a right angle which may create areas of weakness. Likewise, an external transition region between the end portion and the forward side wall portion meet an arcuate transition region

In some forms, the beam body 40 and lugs are fully cast. In the illustrated embodiment, four lugs are shown, however it is understood that the beam body may be cast with three or two lugs or combinations thereof to match the machine hook-up geometry. A beam body having two lugs is shown in FIG. 73.

As shown in FIGS. 4 to 6, the beam body 40 may be assembled from a plurality of cast pieces in varying lengths, with the weld joints between the cast pieces being located in areas of low stress to minimise failure of the joints. For example, welds may be eliminated from the connection point between the lugs and the beam body as the lugs are formed of a single cast piece with the beam body. This is beneficial as the connection point between lugs and the engagement beam body are areas of high stress. The assembly of the engagement beam from multiple cast pieces allows for selection of the correct length and adjustment by trimming one or more of the cast pieces to allow for an accurate length. For example, the beam body 40 and/or the end portion(s) have an adjustable length, and are interchangeable with other components of different lengths to suit particular machines. For example, the beam body having four lugs may be interchanged with a beam body having two lugs to suit the application. This has the advantage of allowing the cast beam to be fitted to many types of buckets and maintain optimal digging aspect ratios. e.g. width-to-height, width-to-tip, width-to-depth.

The engagement beam 12 is formed of one or more cast components welded together or formed as a single cast component which may be re-usable with various baskets. When the baskets are worn, they may be removed from the engagement beam 12 and a new basket may be joined to the engagement beam 12. The engagement beam 12 experiences less wear during use than the basket and thus may be re-usable. The re-usable engagement beam 12 increases the efficiency and performance of the bucket 10, as the basket (or components thereof) may be replaceable when worn.

Referring now to FIGS. 7 and 8, in some forms the engagement beam 12 is formed of a single cast piece. As shown in FIG. 8, the engagement beam 12 includes lug tails 43 which extend from the lugs 41.

In FIGS. 4 to 7 and 9 and 10, the cast beam body 40 and lugs 41 end before the lug tail 43. This allows for different lug tail shapes and configurations to be utilised to fit a variety of basket shapes.

As seen when referring to FIGS. 1 and 9-10, the lug tail 43 extends around the upper shell plate 22 of the basket body 11 and follows the shape of the shell 16. In the illustrated embodiments, the lug tail(s) 43 is substantially triangular-shaped in that it includes three sides: one side abuts the lug 41 (i.e., the lug side 52), one side abuts the shell 16 (i.e., the shell side 54), and one side extends from the lug 43 to the shell 16 (i.e., the free side 56). The sides 52, 54 that abut the other components are coupled respectively to the lug 41 and the shell 16 by welding or any other suitable coupling arrangement.

The lug tail 43 is configured and arranged to be adapted to correspond to different basket shells and/or engagement beams. For example, the shell side 54 of the lug tail 43 can have different radii of curvature to be adapted to different shells having different radii of curvature. The lug tail can be selected from a pool of different sizes of lug tails (e.g., having different widths, lengths and heights) including a range of different radii of curvature to be adapted to abut and follow the gradient of the radii of curvature of the basket shell and/or abut and be aligned with a particular type and size of lug. The lug tail embodiments of the present application allow for an easy and effective way of using the engagement beam (which may be cast) with many different shaped basket shells.

In some embodiments, the lug tails are integrally cast with the engagement beam (e.g., as shown in FIG. 8). Although the lug tails are integrally cast with the engagement beam, the integral lug tail may be configured and arranged to be adapted to correspond to different basket shells. In this way, the casting pattern is customisable to allow different lug tail designs to be swapped in and out as needed.

FIGS. 5 and 11 to 13 illustrate a cross-sectional profile of the beam body 40 and the beam portion 48. One or more inner surfaces define the hollow section central to the beam body 40 and the beam portion 48. The inner surfaces include a floor surface and at least one arcuate top surface. In the illustrated embodiment, the floor surface is planar. The internal profile of the hollow section of the beam body 40 and the hollow section of the shoulder beam portion 48 includes arcuate transition regions providing smooth transitions between the inner surfaces of the engagement beam 12. Each arcuate transition region may include a radius or radii of curvature, and the radius of curvatures may include different radii of curvature. For example, the arcuate transition region at the forward edge of the engagement beam 12 is larger, or has a longer radius, than the arcuate transition region positioned between the floor surface and the arcuate top surface towards the basket.

The beam body 40 and the shoulder beam portion 48 also include one or more outer surfaces which define the components. FIG. 5 illustrates the cross-sectional profile of the beam body 40. An arcuate transition region joins the beam body 40 and the upper shell plate 22. The outer surface of the beam body 40 transitions to a linear transition via a planar surface in line with the internal floor surface of the beam body 40 and the upper shell plate 22. The arcuate transition region provides a smooth transition between the outer surface of the beam body 40 and the upper shell plate 22.

As shown in the embodiments of FIGS. 1 to 13, one or more access portals 45 are disclosed. The access portal 45 in the illustrated form extends into a hollow section central to the beam body 40. The access portal may be located at one or both end faces 46 of the beam body 40. In the illustrated form, the end faces 46 are formed on the end portions 42 of the engagement beam 12, however it will be clear that the access portal may be located at any position along the length of the beam body. The access portals 45 in the cast beam 12 may in some forms provide access to the hollow section in the cast beam that may house devices such as strain gauges and live monitoring devices along with sensors, power sources, communication equipment and data acquisition devices. In addition, systems such as lubrication systems may be located and/or accessed via an access portal provided in the hollow section of the cast beam. The access portals 45 may include a sealed cover 47 to prevent dust and debris entering the access portal.

The access portals may have the benefit of:

- providing access and inspection to the interior of the cast beam;
- acting as openings for hose, tube and cable penetrations to the cast beam;
- incorporating gaskets, o-rings or other sealing methods to seal the cavity and protect the equipment inside from dust and water ingress; and
- be fitted with filters to allow for ventilation of the cavity (if required).

The cover may be affixed or retained to cover the access portal by means of clamps, bolts, welding, adhesives, clips or other affixing methods.

The lubrication system delivers lubricant to the moving parts of the excavator such as the pivot points of the bucket and cylinders. In some forms, at least part of the lubrication system is located in the cast beam. The cast beam is located adjacent or close to the joint between the arm and the bucket and that system, among others, may require lubrication. The location of the lubrication system within the cast beam may be effective. For example, the grease injectors may be incorporated into the cast beam. This configuration may provide protection of sensitive equipment and may improve aesthetics by avoiding exposed brackets and cover plates. It may also assist with overcoming problems associated with the long line lengths in the larger machines.

In some forms the design may be configured to increase strength at certain locations to suit different digging applications; minimise the weight of the beam; include mounting points to securely attach equipment inside; include different compartments for separating different housed equipment; have pockets and cavities for housing sensors and other equipment; include pads and bores for the lubrication system.

In the embodiment shown in FIGS. 14, 15a and 15b, the access portals 1345 may be located centrally on the length of the engagement beam 1312, inside and outside of the basket, and may be located at the end faces. In some forms having the access portals 1345 along the length of the engagement beam provides access to the main pivot points for the lubrication system (e.g., proximal the lugs). In the illustrated embodiment, the access portals 1345 are spaced apart along a forward-facing region of the engagement beam 1312 outside of the basket but with a line of sight to the basket and the basket interior. The access portals 1345 provide access for mounting a camera, sensor or device for monitoring the condition and/or productivity of the bucket.

In FIG. 15b disclosed is monitoring equipment housed in the hollow section of the beam body 1341. The monitoring equipment is configured to monitor the condition and productivity of the bucket. In the illustrated embodiment, the engagement beam is cast. The cast beam 1312 is configured to house monitoring equipment 1390 including communications equipment, sensors, transducers, cameras 1355, onboard processing, power and wiring. The sensors 1351 and cameras 1355 may be fitted to the engagement beam to monitor the condition and/or productivity of the bucket. In FIG. 15a, the sensors 1351 and cameras 1355 are shown fitted in the at least one access portal spaced apart along the beam body in the longitudinal direction.

The engagement beam has controlled and calibrated geometry to achieve repeatable condition and/or productivity monitoring. Further, when the beam is cast, areas of stress concentration that may arise in a fabricated beam may be obviated. As such the cast beam is well suited for housing sensors that monitor bucket conditions and performance. Further as the beams connect the bucket to the machine, the primary loading on the bucket passes through the beam.

Measurement of beam loading can therefore be informative of both the performance characteristics of the bucket and operator performance. The measured loading may include stress, shear and torsion in the beam.

In alternative embodiments, disclosed is a bucket including at least one sensor attached to any of the parts (including the attached wear members (or lip members 13) for engaging the ground. In further alternative embodiments, disclosed is a bucket with at least one sensing device embedded within any of the parts (including the attached wear members or lip member 13).

In the embodiment shown in FIGS. 16 to 22, beading 57 may be formed about the at least one access portal 45 to provide reinforcing to the opening. The beading may be integrally formed on the inner and/or outer surface of the engagement beam 12. The beading 57 provides a thicker region about the access portal 45 to reinforce the opening which may create an area of weakness in the engagement beam 12.

Turning to FIGS. 23 through 25, disclosed is a further embodiment of a bucket 100 comprising a basket body 11 coupled with an engagement beam 12.

The primary difference between the further embodiment and the previous embodiments, is that the side wall is formed as a single component. Like reference numerals will be used for like features.

The basket body 11, in the illustrated form, comprises two side walls 115 which are in a facing arrangement with one another. A shell 16 extends between the two sidewalls. The shell 16 and side walls 115 define an interior cavity 18 therebetween.

The basket body of the bucket is formed of a plurality of plates which may include a lower shell plate 23, upper shell plate 22, and side wall plates 125. The side wall plate 125 is a single plate forming the side wall 115. The side wall plate 125 includes an integral wing plate 126. The side wall may be formed as a single casting. This allows simplified fabrication, removal and replacement of the side wall of the bucket.

The side wall 115 may have a thicker cross section at the forward or leading edge 119 (digging end) where material wear and digging stress is highest. The side wall 115 may be integrally formed with the thicker cross section at the forward edge.

The plurality of plates may be welded or otherwise coupled to form the basket body of the bucket and provide support for a load in the interior cavity. One or more or a selection of plates may be removable either through cutting or otherwise removing the plates from the basket body. The removable plates may form the removable basket portion of the basket body. The side wall plate may be removable from the basket body and may be replaced with a new side wall plate.

Turning to FIGS. 26 to 38, disclosed are further embodiments of a bucket 200, 300 comprising a basket body 211, 311 coupled with an engagement beam 12. The primary difference between the further embodiments and the previous embodiments is that basket body 211, 311 includes an upper portion 260, 360 and a lower portion 262, 362. Like reference numerals will be used for like features. The primary difference between the bucket 200 and the bucket 300 is they include different embodiments of wing plates.

The basket body 11, in the illustrated form, comprises two side walls 215, 315 which are in a facing arrangement with one another. A shell 216, 316 extends between the two sidewalls. The shell 216 and side walls 215 define an interior cavity 18 therebetween.

The lower portion 262 also includes at least one lower side wall plate 266. The at least one lower shell plate 223 forms part of the shell 16.

The basket body 211 including the upper portion 260 and the lower portion 262 of the bucket is formed of a plurality of plates which may include the lower shell plate 223, the upper shell plate 222, and the side wall plates 264, 266. The plurality of plates may be welded or otherwise coupled to form the basket body of the bucket and provide support for a load in the interior cavity.

The upper portion 260 and the lower portion 262 are joined along a join. The upper and lower side wall plate are joined along the join. The upper and lower shell plates are joined along the join. The join may be continuous, non-continuous, non-linear, linear, and may include corners. At least a portion of the lower portion 262 and the at least a portion of the upper portion 260 may be separated along the join to allow the portion of the lower portion 262 or the lower portion 262 of the basket body 211 to be replaced when worn, for example. The upper portion 260 may be reused with a new portion of the lower portion 262 of with a new lower portion 262. The upper portion 260 and the lower portion 262 may be separated through cutting or otherwise removing the lower portion 262 from the basket body 211. The lower portion forms a replaceable lower portion.

Each of the upper and lower portion include an upper and lower wing plate 268, 270. The upper and lower wing plates 268, 270 may be formed separately to the upper and lower side wall plates 264, 266 and coupled together or integrally formed. The upper wing plate 268 may form part of the end portion 42 or may be formed separated and coupled to the end portion 40.

In the embodiment shown in FIGS. 33 to 38, the lower wing plate and the upper wing plate are unequally sized. The lower wing plate 370 extends from the forward edge 20 up to a smaller upper wing plate 368. The smaller upper wing plate 368 may be coupled to or formed integrally with the end portion 42.

In this further embodiment, the lower wing plate 370 may not be removed when the remainder of the lower portion 362 is removed to be replaced. As shown in FIGS. 37 and 38, the lower side wall plate 366 and the lower shell plate 323 are shown as separated from the basket body 11, and the lower wing plate 370 remains coupled to the basket body 11 and the engagement beam 12.

One or more or a selection of plates of the lower portion may be removable either through cutting or otherwise removing the plates from the basket body. The removable plates may form the removable basket portion of the basket body. In alternative embodiments, at least a portion of the upper portion may be removed with the lower portion leaving at least a portion of the upper portion to be reused with a new lower portion and the portion of the upper portion that was removed.

Turning to FIGS. 40 to 60, further embodiments of a bucket 400, 500, 600, 700, 800, 900 are shown. The bucket 400 comprises a basket body 11 coupled with an engagement beam 12. The further embodiments of the engagement beam 412, 512, 612, 712, 812, 912 include embodiments of at least one support 472, 572, 672, 772, 972. Like reference numerals will be used for like features.

The engagement beam 412, 512, 612, 712, 812, 912 extends along a longitudinal axis between two end faces 46 and includes a plurality of lugs 41 extending in a lateral direction from a beam body 40. The beam body 40 includes an internal surface 472 defining a hollow section extending centrally therethrough. The at least one support 472, 572, 672, 772, 972 extends along the internal surface 473, 573, 673, 773, 973. The at least one support provides strength and rigidity to the beam body. The at least one support may be positioned externally or internally relative to the beam body depending on where it is positioned relative to the lug. Different embodiments of supports suit a variety of difference machines and ground engaging styles as well as minimising the overall weight of the beam body by optimising material use. Inclusion of the at least one support allows for the engagement beam to include a hollow section. The hollow section provides access, clearance and mounting opportunities for equipment housed inside the beam body, for example, a lubrication system.

In the embodiment shown in FIGS. 39 to 42, the support 472 is in the form of an internal support 472 extending about the inner surface substantially aligned with the respective lug 41. The internal support 472 is a similar width to the lug 41 and extends into the hollow section from the internal surface 473. The internal support 472 may be continuously extending about the internal surface 473, but may also be interrupted and equally spaced apart or unequally spaced about the internal surface. An arcuate transition region extends between the internal support 472 and the inner surface 473. The internal support may taper in width and is not required to be a consistent width.

In the embodiment shown in FIGS. 43 to 46, the internal support 572 extends about the inner surface 573 and is offset in the longitudinal direction from the respective lug 41. Each of the lug 41 and the internal support 573 includes a central axis (i.e., a centreline) extending in the lateral direction. The central axis of the lug is offset in the longitudinal direction from the central axis of the internal support while extending in the same general lateral direction from the respective surfaces of the beam body. A portion of the internal support and a portion of the lug may overlap and extend in a plane in the same lateral direction. For example, an end face of the internal support may be generally in line with the centreline of the lug.

In the embodiment shown in FIGS. 47 to 50, there are dual internal supports 672 extending about the inner surface 673 of the beam body flanking the respective lug 41. The dual internal supports are offset in the longitudinal direction from the respective lug 41.

In an alternative embodiment, an internal support extends about the inner surface at an angle relative to the lug and the longitudinal axis. A portion of the internal support may be aligned with or adjacent to the lug and diverge out of alignment or into alignment with the lug in the direction of the longitudinal axis along the inner surface at an angle like a helix. The angle may be constant or variable relative to the longitudinal axis of the beam body. The pitch of the internal support may also be variable or constant.

In a further alternative embodiment, the internal support extends about the inner surface of the beam body out of plane with the respective lug. The central axis of the internal support extends in a different plane to the central axis of the lug. For example, the central axis of the lug may extend in a plane at an angle Θ to a plane of the central axis of the internal support.

In further alternative embodiments, the internal support may also be a combination of any one of the embodiments disclosed herein. For example, the internal support may extend in a different plane to the lug and be longitudinally offset to the lug.

In the embodiment shown in FIGS. 51 to 53, the bucket 700 includes the at least one support 772 which extends in the longitudinal direction further than in the lateral direction from the beam body. In the illustrated embodiment, the at least one support is in the form of a sleeve 772 positioned internal the beam body and in line with the respective lug 41. The sleeve 772 provides a thicker beam section around the lug 41. The sleeve 772 may be integrally formed with the beam body. The sleeve 772 may be aligned with the lug 41 so as to extend on either side of the lug 41 in equal portions and/or the sleeve may extend between the lugs. In alternative embodiments, the sleeve may be positioned external the beam body. The external support sleeve may be aligned with the lug so as to extend on either side of the lug in substantially equal portions, and/or the sleeve may extend between the lugs.

In the embodiment shown in FIGS. 54 to 58, a further embodiment of the bucket 800 is disclosed. The engagement beam 12 includes an inner surface 873 defining a hollow section without at least one support. In particular, where the beam body does not include at least one internal support, more storage space in the hollow section inside the beam body is provided which also provides better access for equipment stored inside the beam.

In the embodiment shown in FIGS. 59 to 61, the bucket 900 includes an internal support 972 being aligned with a respective lug 41. The lugs and supports may have non-uniform thickness. In the illustrated embodiment, the lug is wider in the longitudinal direction than the support 972.

Turning to FIGS. 62a to 65b, a further embodiment of a bucket including an engaging beam 1012 is shown. The bucket comprises the engagement beam 1012 configured to be coupled to a basket body as disclosed herein. Like reference numerals are used for like features.

The engagement beam 1012 comprises a beam body 40 extending along a longitudinal axis between ends. A plurality of lugs 41 extends from the beam body 40 in a lateral direction for attachment to a machine for excavating or the like. Each lug 41 extends between a first side face and second side face. The first side face and the second side face join the beam body 41 at a respective arcuate transition 49. Each lug 41 includes inner walls defining a forward bore 1074 and a rear bore 1076. The forward and rear bores 1074, 1076 also extend between the first side face and the second side face. Each bore extends along a bore axis. The respective bore axes extend in the same direction as the longitudinal axis of the beam body. The lug 41 also includes forward and rear bosses 1078, 1080 circumscribing the forward and rear bores 1074, 1076. The boss 1078, 1080 is a thicker section of the lug 41 surrounding the bore 1074, 1076 to provide reinforcing to an area of the lug 41 which undergoes significant load transfer through its connection to the excavator machine. The boss 1078, 1080 may be formed on the first and/or second side faces.

In the embodiment shown in FIGS. 62a to 65b, disclosed is a method of manufacturing an embodiment of at least one boss of a lug may include the following steps:

- casting an engagement beam including a plurality of lugs, each lug includes at least one boss being oversized; and
- machining the at least one boss to a finished boss including a predetermined tolerance and/or finish.

The step of machining the at least one boss may include the following steps:

- chamfering at least a portion of an edge of the at least one boss;
- machining or facing a surface of the at least one boss;
- machining a bore in the at least one boss; and
- drilling holes 1082 in the boss about the bore for attachment and alignment of thrust plates.

The method may further comprise inserting a bush in the bore of the at least one boss.

Turning to FIG. 65b, the method further comprises line boring the plurality of bores formed in the plurality of lugs of the engagement beam. This step may be performed before or after the engagement beam has been welded to the basket.

The integral nature and rigidity of the cast engagement beam including the plurality of lugs facilitates this step to occur earlier (and more conveniently) in the bucket fabrication process than is known in the prior art.

Turning to FIGS. 67 to 69, a further embodiment of a bucket 1100 is shown. The bucket 1100 comprises a basket body 11 coupled with an engagement beam 1112. The further embodiments of the engagement beam 1112 include embodiments of at least one projection 1182. Like reference numerals will be used for like features.

The engagement beam 12 extends along a longitudinal axis between two end faces 46 and includes a plurality of lugs 41 extending in a lateral direction from a beam body 40. The beam body 40 includes an internal surface 1173 defining a hollow section extending centrally therethrough. The at least one projection 1173 extends from the internal surface 1173. The at least one projection provides a fixing point for mounting equipment. For example, the equipment may include sensors, cameras, electronics, wires, lubrication system, pipe, hose, clamps and fittings etc.

The at least one projection 1173 can be located anywhere on the internal surface of the cast beam. For example, in the illustrated embodiment, the at least one projection is aligned with the respective lug for mounting a grease fitting. A channel may be provided (e.g., drilled) from the bore(s) of the lug to the protrusion. The grease fitting may be mounted to the protrusion. A hole may be tapped to create a threaded hole internal the beam body in the protrusion, so as to receive a corresponding thread of the grease fitting.

The beam body 11 also includes an outer surface 1183 and the plurality of lugs 41 extend from the outer surface 1183. A wall 1186 is formed between the inner and outer surfaces. The wall 1186 may have a variable thickness between the inner and outer surfaces. Sections of the wall are defined by the plurality of lugs and in some embodiments, the internal supports respectively aligned with the plurality of lugs. In the illustrated embodiment, a first section 1188 is formed between the end face 46 and including a first lug 1189. A second section 1190 is formed including a second lug 1191 and a third lug 1193. A third section 1192 is formed between the third lug and a third lug. A fourth section is formed between the third lug and the opposite end face 46 including a fourth lug 1195. The first and third sections do not necessarily include the end faces and may extend in the direction towards the end faces. Extending in the longitudinal direction one or more of the sections of the wall may taper in thickness between the outer and inner surfaces. At least a portion of the tapered wall section may also extend in the lateral direction about longitudinal axis and/or in a transverse direction to the longitudinal axis. An internal support is also shown in line with each lug.

A reinforcing member 1182 is positioned along at least a part of the join of the sections along the internal surface 1173. In the illustrated embodiment, the reinforcing member 1182 circumscribes the internal surface 1173 of the beam body along at the join. The reinforcing member 1182 may be integrally formed with the beam body to form a thicker central region as discussed herein in relation to a further embodiment. The reinforcing member 1182 alleviates stress along the join, particularly at the join proximal or at the inner surface, where it is more difficult for a technician to access and dress the weld.

FIG. 68 is a close-up view of the reinforcing member 1182 reinforcing the join prior to welding. Once the sections are brought together and welded the sections will be fused together and the gap between the sections will be minimized, and in some embodiments, eliminated. The sections will form a continuous wall of the beam body. In alternative embodiments, the reinforcing member may be integrally formed with one of the sections and then as the sections are joined in an end-to-end configuration, the reinforcing member will overlap the adjoining section and subsequently welded together.

Turning to FIGS. 70 to 72, disclosed is a further embodiment of an engagement beam 1212 for a bucket 1200. Like reference numerals are used for like features. The engagement beam 1212 is configured to support a basket to form a basket interior. The engagement beam 1212 comprises a beam body extending along a longitudinal axis between ends. The beam body 11 includes an inner surface defining a hollow section extending centrally therethrough. The engagement beam also includes a plurality of lugs 41 extending from an outer surface 1283 the beam body 11 in a lateral direction. A wall 1284 is formed between the inner and outer surfaces 1273, 1283.

In the close-up view of FIG. 72, a first region of the wall 1284 is illustrated as tapering from the first lug/first support towards a central region between the first and second lugs (and the first and second supports). In the first region, the outer surface 1283 is substantially parallel with the longitudinal axis of the beam body and the inner surface 1273 is tapering. The central region may include a thicker region 1282 circumscribing the beam body 40, and extending from the inner surface 1273. The thicker central region may include a reinforcing member 1282 extending along the internal surface of the beam body along the join between the sections of beam body.

The second region diverges from the central region 1282 to the second lug 41 or tapers from the second lug to the central region 1282. The second region is thicker proximal each lug and thinner towards the central region. The taper accommodates casting efficiencies. It is understood that any one or more of the sections may have a tapering thickness.

The reinforcing member may be integrally formed with the beam body to form a thicker central region as discussed herein in relation to a further embodiment. The reinforcing member alleviates stress along the join, particularly at the join proximal or at the inner surface, where it is more difficult for a technician to access and dress the weld.

Turning to FIG. 73, disclosed is a further embodiment of an engagement beam 1312 for a bucket 1300 is disclosed. The engagement beam includes a beam body 40 and two lugs 41 extending from the beam body 40. In alternative embodiments, three lugs may extend from the beam body, or any suitable number of lugs may be included depending on the machine that

While the illustrative examples pertain to an apparatus of a mining apparatus, such as a bucket for excavation equipment or a ground digger, the system has application to other types of apparatuses, such as a backhoe for a dragline bucket.

In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
