What should you do if you suspect brake failure during operation?

• A. Stop operation and report to supervisor for immediate service
• B. Ignore and continue if the load is light
• C. Continue operation and monitor the brakes
• D. Increase load to test the brakes

Answer: (D)

Brake failure in a mobile crane is a critical safety issue that demands immediate action. If you suspect the brakes aren’t functioning, the priority is to bring the crane to a complete, controlled stop and stop further operation. This means engaging the appropriate emergency or safety stop if available, then securing the area and informing a supervisor so qualified maintenance can inspect and repair the system. Continuing to operate or testing the brakes by increasing the load introduces the risk of uncontrolled movement or a dropped load, which can injure workers and damage equipment. Only after a trained technician confirms the brakes are repaired and safe should you resume operation.
