🔍 Key Concepts

• Lifeboat davit limit switches and what they physically do when the boat reaches its normal stowed position • How over-travel of the davit arms or falls (wires) could affect the mechanical parts involved • The difference between protecting wires, winch motor, and releasing gear

💭 Think About

• Ask yourself: does a limit switch usually control speed of lowering, end of travel, or release of the boat? • When the lifeboat is being HOISTED back into the davit, what part of the system is most at risk if the winch keeps pulling after the normal stowed position? • Which component would be most directly affected if the falls (wires) are kept under increasing tension with no more movement possible?

✅ Before You Answer

• Be clear on whether limit switches act at the top or bottom of travel, and in which direction (hoisting vs lowering) they are most critical • Consider which choice describes a consequence of over‑hoisting or over‑travel, not normal operation • Verify which option involves excessive strain in the falls (wires) and davit system, rather than control of lowering speed or releasing-gear operation
