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.

Abstract: A rollover protection structure (ROPS) for a work machine includes a rigid strut having a fixed longitudinal length. On one end of the strut, a pivot end mechanism is attached that has a mounting plate that pivots relative to the strut. On the opposite end of the strut, a jack end mechanism is attached that has a mounting plate that extends longitudinally relative to the strut. When installed, e.g., with the mounting plate on each end of the strut being affixed to the work machine such as by welding, the ROPS can be extended to span an opening in the chassis of the work machine and to impart specific compression/tension on the strut. Moreover, the jack end mechanism can be disassembled, while its mounting plate remains affixed to the work machine, and the strut can be rotated about an axis in pivot end mechanism about which the mounting plate therein pivots.
