Question: During a pre-shift inspection, the mobile crane operator finds that one of the outrigger control levers is stiff and not returning to the neutral position smoothly. What is the appropriate action to take?
Answer options:
- Apply a small amount of grease to the lever mechanism and re-test.
- Use increased force to operate the lever, assuming it will loosen up with use. ✅ Report the issue immediately to a supervisor and do not operate the crane until the control is freely operative and confirmed safe.
- Operate the crane but avoid using that specific outrigger, relying on the others for stability.
Correct answer: Report the issue immediately to a supervisor and do not operate the crane until the control is freely operative and confirmed safe.
Explanation: Any issue with controls that prevents smooth and proper operation can compromise safety. A stiff or improperly returning control lever for an outrigger indicates a potential malfunction that must be investigated and repaired by qualified personnel before the crane is put into service.
