The two major components of a ROPS (Roll Over Protective Structure) system are the roll over protection cab or bar and the seat belt. ROPS is designed to protect the operator and the machine during a rollover incident. The roll over protection cab or bar provides a structural frame that absorbs and deflects the force of a rollover, while the seat belt is essential for keeping the operator securely in place within that protected space, preventing ejection from the cabin.

Together, these components work effectively to minimize the risk of injury during an overturn. The roll over protection bar or cab serves as a shield, while the seat belt ensures that the operator remains inside and benefits from that shield. This combination is crucial for enhancing the safety of operators working with heavy machinery, particularly in environments where rollovers are a risk. The other options do not contribute to the primary function of a ROPS system, which is specifically geared towards protection from rollovers.
