🔍 Key Concepts

• Operation of gravity davits and how they are normally stopped in the raised position • Purpose of hand cranking at the end of hoisting and what risk it avoids • Function of mechanical stops vs. electrical limit switches in winch systems

💭 Think About

• Ask yourself: Which stopping point is designed as a positive mechanical stop that does not depend on electricity or a switch working correctly? • Why would the procedure call for hand cranking only in the final part of the hoist, instead of using full power all the way up? • Which option best prevents over‑hoisting and damage if something in the electrical system fails?

✅ Before You Answer

• Identify which choice refers to a built‑in mechanical stop on the davit, not just a switch or a deck level • Consider which method would be safest if the limit switch failed or was out of adjustment • Verify which option allows the winch to do most of the work, but still uses manual control for precise final positioning
