When using the hand crank to retrieve and stow a lifeboat on gravity davits, which of the listed precaution should always be observed?

🔍 Key Concepts

• Safe operation of gravity davits when handling lifeboats • Purpose of hand brakes, limit switches, and disconnect switches on launching appliances • Risk of uncontrolled movement or electrical operation while using a manual hand crank

💭 Think About

• When you are using a hand crank, what type of motion (manual or electric) should be in control, and which safety devices should remain active? • Which option would clearly increase the risk of the boat moving unexpectedly while you are cranking? • Think about which device is meant to protect you from runaway movement versus which are for electrical isolation or emergency use.

✅ Before You Answer

• Identify which item directly prevents uncontrolled rotation or runaway hoisting/lowering during hand-crank use. • Ask: Would this action defeat or bypass an important safety device? If yes, that is likely NOT correct. • Confirm which component (brake, disconnect, limit switch, crank lock) is intended to be positively engaged/secured when manual handling is in progress.
