• A. True
• B. False
• C. Depends on the situation
• D. No action required

Answer: (A)

When a radio-controlled crane malfunctions, safety demands an immediate stop of all movements and de-energizing the control system. A loss of reliable control can lead to unintended motions if signals are garbled, lost, or interfered with, putting nearby people and equipment at risk. Turning off the master switch cuts power to the crane’s control circuits, preventing any further commanded or residual motion and creating a safe condition to assess and repair the fault. After stopping, the area should be secured and a qualified technician should inspect the radio unit, batteries, receivers, interlocks, and wiring before re-energizing. This approach avoids waiting for a fault to worsen and aligns with the principle of stopping operations until the system is safe to resume.
