178. Why is an upper limit switch used when raising the lifeboat?

The upper limit switch prevents davits from impacting their mechanical stops, safeguarding the davit system and falls from overload. This switch automatically cuts power to the winch when the lifeboat reaches its upper limit, preventing over-hoisting and potential damage to the davits, winch, or falls; it does not assist with cranking, manage tricing lines, or control lowering.
