  • Patent number: 11993324
    Abstract: A guard assembly for a work machine includes at least one guard including a body. The body in part defines a volume, a first opening, at least one second opening, and at least one pair of first retention tabs. The door defines a first end and a second end. In an open position of the door, the door provides access to the volume and, in a closed position of the door, the door limits access to the volume. The door includes a plate removably coupled to the guard proximal to the first end of the door by at least one fastener, and at least one coupling arrangement extending from the plate for pivotably coupling the plate to the guard proximal to the second end of the door. The coupling arrangement includes a first portion coupled to the plate and a second portion extending from the first portion.
    Type: Grant

  • Patent number: 10144379
    Abstract: A radiator guard assembly for a machine includes an aperture plate. The radiator guard assembly also includes a first side sheet extending perpendicularly with respect to the aperture plate. The radiator guard assembly further includes a second side sheet extending perpendicularly with respect to the aperture plate. The second side sheet is spaced apart from the first side sheet. The radiator guard assembly includes a mounting structure coupled to each of the first and second side sheets. The mounting structure includes a base member coupled to the respective side sheet. The mounting structure also includes a first plate extending from the base member. The first plate defines a first aperture. The mounting structure further includes a second plate extending from the base member. The second plate is parallel to first plate. Further, the second plate defines a second aperture that is coaxial with the first aperture.
