  • Publication number: 20260002333
    Abstract: A digging attachment for an industrial excavating machine includes a first housing portion including a first housing opening, a second housing portion including a second housing opening, and an intermediate portion positioned between the first housing portion and the second housing portion. The intermediate portion may be one of a plurality of intermediate portions each having a different length that corresponds to a different volume of a cavity of the digging attachment. The length of the intermediate portion can determine the volume of the cavity. The intermediate portion may have open ends that complement a profile of the first and second housing openings. The cavity may have a substantially continuous profile between the first housing opening, the open ends of the intermediate portion, and the second housing opening. The intermediate portion may be omitted and the first housing portion may be directly couplable to the second housing portion.

  • Publication number: 20250198133
    Abstract: Tooling systems for a digging attachment include one or more tooth assemblies including a moveable tooth. A working length of the tooth may be adjusted and/or replenished by movement of the tooth in response to wear or damage on the tooth. The tooth assembly includes the tooth and a shroud that is positioned adjacent a lip of the digging attachment. The tooth is moveable within a cavity of the lip relative to the shroud, and through an opening defined in the shroud.

  • Patent number: 10929820
    Abstract: Systems and methods for predicting replacement of a component of an industrial machine. One system includes an electronic processor configured to determine a wear rate of the component based on a current dimension of the component and historical dimensions of the component and determine a replacement cost for the component. Determining the replacement cost includes determining a cost of downtime for replacing the component based on a time for replacing the component and a downtime cost for the industrial machine during the time for replacing the component, a material cost in replacing the component, and an operating cost of the industrial machine associated with not replacing the component. The electronic processor is also configured to determine a replacement recommendation for the component based on the wear rate, the replacement cost, and discard criteria and output the replacement recommendation.
