A fatigue life optimized modular bucket assembly for a work machine and a method of manufacturing thereof are disclosed. The bucket assembly includes a bucket core having a pair of side sections, a continuous wrapper, a supporting element, and a receptacle; and an extension module having a pair of side bars, a guard module, an edge module, and, optionally, a set of extension plates. The method includes prebuilding the bucket core, receiving an order, providing parts for the extension module, and assembling the bucket core and the extension module parts. The bucket assembly may include universal and customizable components without exhibiting reduction to fatigue life commonly associated with weld seams.

Fatigue life optimized modular bucket assembly

A method includes, with a processor executing computer-readable instructions stored within a memory device, displaying, on a display device and via at least one graphical user interface (GUI), a first interface element associated with a machine selection, receiving, via the first interface element, a first input comprising an indication of a machine, displaying, on the display device and via the at least one GUI, one or more second interface elements associated with tool parameters, receiving, via the second interface element, a second input comprising an indication of the tool parameters, determining, based at least in part on the machine and the tool parameters, one or more tools for use with the machine, and presenting, via the at least one GUI, a graphical representation of the one or more tools.

Tool selection systems

An implement system includes a linkage and a bucket coupled with the linkage and movable between a dump position and a racked position. The bucket has a compound back section that forms a profile having a basin shape to assist in distributing material within the back section when the bucket is curled, and nesting the bucket close to the linkage. Related methodology is disclosed.

Adapter for a ground engaging machine implement

A tip adapter comprises a side throat surface with a variable blend defining a radius of curvature ranging from 200 mm to 270 mm, or a lower nose surface that includes a first planar portion and a second planar portion defining a lower obtuse angle therebetween, or a top throat surface with a top arcuate portion defining a radius of curvature ranging from 100 mm to 300 mm.

Heavy duty adapter

A tip defining a cavity for being attached to a work implement comprises a body that defines a cavity with a cavity upper flat portion length ranging from 5 mm to 20 mm, or a cavity side transition surface configured to avoid interference with a tip adapter, or a cavity first lower planar surface that forms an oblique angle with the cavity second lower planar surface.

Heavy duty tip

A hinge attachment bracket for use with a work implement is provided. The bracket comprises a substantial I-beam configuration that includes a first flange, a second flange, a web that connects the first flange to the second flange and that defines a boss that defines a pin receiving bore that establishes a radial direction, a radial plane and a longitudinal axis. The first and second flanges may merge toward each other tangentially forming a first extension portion.

Upper hinge design for a bucket

A bucket comprises a shell including a curved member that defines a first transverse end, a second transverse end, a top edge and a bottom flat portion, a first flat angled member attached to the first transverse end of the curved member and a second flat angled member attached to a second transverse end of the curved member, a bottom member, and at least one attachment bracket, wherein the bucket assembly defines a bucket center plane and the first and second flat angled members are tapered toward the center plane of the bucket.

Multi-component shell profile for a bucket

A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.

Tilt bucket profile and front structure

A tilting bucket assembly comprises an adapter subassembly including a two coupler members defining a coupler distance, a base plate attached to the coupler members that defines a first recess, a torsion tube that defines a second recess, and a bucket subassembly that is pivotally connected to the adapter subassembly, the bucket subassembly including a spill guard including a stop portion configured to contact the adapter subassembly, and a tilting mechanism, wherein the first recess and second recess clear the tilting mechanism and the spill guard when the base plate contacts the stop portion of the spill guard.

Tilt bucket recessed pivot design

A wear assembly for a loader bucket. The wear assembly includes a first side plate coupled to the side wall and a second side plate spaced apart from the first side plate, coupled to the side wall. The wear assembly includes a top plate disposed on the first side plate and the second side plate. Further, the top plate has a first end disposed proximal to the side wall and a second end distal from the side wall. The wear assembly includes a shroud member disposed adjacent to the second end of the top plate and coupled to the first side plate. The wear assembly also includes a wear plate disposed adjacent to the first end of the top plate in front of the shroud member. The wear plate is detachably coupled to an upper surface of the top plate.
