However, due to the small diameter of the manhole cover on the deck surface of the ship, for large ocean-going ships, the ship's cabin is far from the deck. Therefore, in order to ensure that the cargo oil pump equipment in the cabin can go out of the cabin smoothly, it is necessary to take measures to lift it by means of a lifting device.
