Here is rewritten text: The davit crane turns manually using a bar and gets locked in place with a "T" pin, as well as a manual winch that aids rotation. To keep the bearing rings lubricated, 1/4-inch plugs serve as grease points on top of the rings and along the central pipe that runs between them. In addition to this setup, the crane's base features similar plugs for greasing pipes inside it, which help smooth its rotation when extended or lowered.
