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

The limit switch on gravity davits is designed primarily as a safety mechanism that cuts off power when the davits are near the safety stops. This ensures that the davits do not exceed their designated range of motion, which could lead to potential safety hazards or mechanical failure. When the davits approach the limits of their movement, the limit switch activates and disables the power, preventing any further operation that might cause damage or compromise safety.

This feature is crucial for maintaining the integrity of the lifting apparatus and ensuring the safe deployment and retrieval of lifeboats. By stopping power at these critical points, the limit switch helps protect both the equipment and the personnel working with it. Understanding the function of the limit switch is vital for any crew member involved in lifeboat operations, as it is an essential component of the overall safety and functionality of the gravity davit system.
