Answer & Explanation
The correct answer is Option C: C) To cut off the power when the davits are about 12 inches or more from the track safety stops.
Limit switches serve as a safety cut-out for the electrical winch motor. They must be positioned to stop the davit arms before they reach the physical track safety stops, typically 12 inches (approx. 300mm) before the end of the track, to prevent structural damage.
