Rollover Protective Structure (ROPS) and Falling Object Protective Structure (FOPS) - Inspect
检查防翻滚保护架（ROPS）/落物保护系统（FOPS）的螺栓是否松动或损坏。 只能用原产更换件更换任何损坏和缺失的螺栓。 拧紧螺栓至扭矩为 900 ± 100 N·m (660 ± 75 lb ft)。
注: 安装 ROPS/FOPS 螺栓前，在 ROPS 螺栓螺纹上涂抹机油。 如果没有在螺纹上涂抹机油，则可能会导致不正确的螺栓扭矩。
不要在 ROPS/FOPS 上焊接加强板，来矫直ROPS/FOPS。 不要在 ROPS/FOPS 上焊接加强板，来修理ROPS/FOPS。
如果 ROPS/FOPS 在焊缝、铸件或任何金属部分出现了泄漏，请咨询您的 Caterpillar 代理商进行修理。
