    Abstract: An axle, for a mining machine, includes one or more segments, each defining a first wall portion, a second wall portion disposed opposite to the first wall portion, a third wall portion, and a fourth wall portion. The third wall portion extends between the first and the second wall portions to meet the first wall portion at a first corner portion and the second wall portion at a second corner portion. The fourth wall portion extends between the first and the second wall portions to meet the first wall portion at a third corner portion and the second wall portion at a fourth corner portion. The second thickness of the second corner portion and the third thickness of the third corner portion are greater than each of the first thickness of the first corner portion and the fourth thickness of the fourth corner portion.

  • Patent number: 12168383
    Abstract: A retainer for retaining a pin with a section of a work machine. The retainer includes a body to be reversed between a first state and a second state to secure the pin with the section in each of the first state and the second state. The body defines a retaining portion and a securing portion. The securing portion is fixedly coupled to the retaining portion and defines through-holes. In the first state, the through-holes are aligned with apertures of the section for coupling the body to the section such that the retaining portion acquires first orientations relative to the section to engage the pin according to the first orientations. In the second state, the through-holes are aligned with the apertures for coupling the body to the section such that the retaining portion acquires second orientations relative to the section to engage the pin according to the second orientations.
