Publication number: 20240157903Abstract: 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.Type: ApplicationFiled: November 11, 2022Publication date: May 16, 2024Applicant: Caterpillar Inc.Inventors: James D. COSTNER, III, Scott M. SHAFFER, Paul IVES, Ashraf I.S. IDKAIDEK
