  • Patent number: 11952751
    Abstract: A shroud retention system for a work tool is disclosed. The shroud retention system may have an adapter attached to the work tool. The shroud retention system may also have a shroud that slidably engages with the adapter. The shroud may have a retainer slot. Further, the shroud retention system may have a spring assembly disposed in the shroud. The spring assembly may have a block that slidably moves relative to the adapter. The spring assembly may also have a resilient member disposed between the adapter and the block. In addition, the spring assembly may have a retainer disposed in the retainer slot. The retainer may engage with the block. The retainer may have at least one recess disposed on the retainer front face or on the retainer rear face. The recess may extend partway toward the other of the retainer front face or the retainer rear face.

  • Publication number: 20230313502
    Abstract: A work machine comprising a trench measurement system for measuring a trench depth and trench angle during a trench digging operation is disclosed. The work machine comprises a range finder system mounted on the boom and includes a plurality of rangefinders, each rangefinder includes a beam device configured to determine a distance of a plurality of rays irradiated from the beam device to a trench floor. An on-board controller is configured to calculate the trench depth from data received by the range finder system on the boom, the sensor assembly, the boom position on the working mechanism, and attributes of the work machine. A method for measuring a trench depth and trench angle associated with a trench digging operation with range finders mounted on the boom of a work machine is also disclosed.

  • Patent number: 11174890
    Abstract: A fastener retaining component may comprise a first elongated member. A length of the first elongated member may be greater than a diameter of a fastener receiving element of a component. The fastener retaining component may further comprise a second elongated member. A length of the second elongated member may be greater than the diameter of the fastener receiving element. The fastener retaining component may be configured to be press-fit within the fastener receiving element such that press-fitting the fastener retaining component, within the fastener receiving element, increases a tension in the fastener retaining component to cause the first elongated member and the second elongated member to engage with an inner surface of the fastener receiving element and to retain a fastener within the fastener receiving element.
