🔍 Key Concepts

• Davits and limit switches on lifeboat winch systems • What happens if davits or sheaves are raised too far (mechanical stops, damage, shock loading) • How automatic cut‑off devices protect equipment and people during hoisting operations

💭 Think About

• When you are RAISING a lifeboat, which part of the system is most at risk if movement is not stopped in time? The boat, the lines, or the davit structure? • Think about what a limit switch normally does in machinery (like cranes, elevators, winches). Is it meant to help you operate, or to automatically stop over‑travel? • Which options describe preventing DAMAGE to equipment, and which describe helping with normal operation or lowering instead of raising?

✅ Before You Answer

• Identify which answers actually relate to raising (hoisting) rather than lowering • Ask yourself: a limit switch is an automatic stop to prevent over‑travel — which option best matches that function? • Eliminate any choice that refers to assisting or manual operations, rather than preventing impact or over‑travel at the top of the davit’s travel
