What is the purpose of the rollover protective structure (ROPS) on wheel loaders?

• A. To improve fuel efficiency.
• B. To protect the operator in case of a rollover by maintaining a protective space around the operator.
• C. To increase bucket capacity.
• D. To enhance cab ventilation.

Answer: (B)

Rollover protective structures are built to keep the operator safe if the loader tips over. They’re a reinforced frame that surrounds the cab and maintains a protective space around the operator so the cab doesn’t crush or deform in a rollover. This safety feature works best when the operator is wearing a seat belt, because the belt helps keep the person inside the protected space. It isn’t about fuel efficiency, bucket capacity, or cab ventilation—those are handled by different systems.
