What is the purpose of the limit switch on gravity davits?

🔍 Key Concepts

• Gravity davits operation and how lifeboats are launched safely • Role of track safety stops on davit tracks • What a limit switch normally does in electrical/mechanical systems

💭 Think About

• Think about what could happen if the davit arm were allowed to travel all the way until it physically hits the track safety stops under power. • Ask yourself whether a limit switch is usually designed to control speed, position, or both. • Consider at what point you would want the electric power cut off so that the davit can be safely controlled the rest of the way.

✅ Before You Answer

• Verify that track safety stops are last-resort mechanical stops, not routine stopping points under power. • Confirm that a limit switch is typically triggered before mechanical contact or damage occurs. • Check which option best reflects a preventive safety function rather than allowing impact and then cutting power.

What is the purpose of the limit switch on gravity davits?

To stop the davits from going too fast

To cut off the power when the davits are about 12 inches or more from the track safety stops

To cut off the power when the davits hit the track safety stops

None of the above
