  • Patent number: 12596004
    Abstract: A system for determining a position of a pin inserted within a pinhole of a work machine is disclosed. The system includes a follower, a sensor, and a controller. The follower is biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole. The sensor is configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole. The controller is configured to determine the position of the pin based on the state of the follower.

  • Publication number: 20260062895
    Abstract: A wear plate for a work implement of a work machine includes a body extending along a longitudinal axis, a lateral axis orthogonal to the longitudinal axis, and a vertical axis orthogonal to the longitudinal axis. The body defines an engagement surface, an operational surface opposite the engagement surface, and a cut-out extending from the engagement surface to the operational surface. The wear plate also includes at least two projections extending outwards from the engagement surface along the vertical axis. Each of the at least two projections is adapted to be received within a base structure of the work implement to removably couple the wear plate with the work implement, such that the at least two projections are isolated from the operational surface of the wear plate.

  • Patent number: 12523016
    Abstract: A work implement for a construction machine includes a collection member, a first side wall, a second side wall, and a plate member coupled to the collection member, the first side wall, and the second side wall. The collection member, the first side wall, the second side wall, and the plate member together define a hollow space. Further, at least one of the first side wall, the second side wall, and the plate member define an opening that communicates with the hollow space. The work implement further includes a sensor mounting system including a cover, a plurality of mechanical fasteners adapted to couple the cover with the work implement, and a sensor mounted on the cover. Upon coupling of the cover with the first side wall, the sensor is partially received within the hollow space.

  • Patent number: 11079921
    Abstract: 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.

  • Patent number: 10246848
    Abstract: 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.

  • Patent number: 9957689
    Abstract: 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.
