Provided is a ladder of a ship, which has a cover automatically opened by recognizing the heel angle of the ship to extract the ladder folded and stored in the ship. The ladder of a ship comprises: a main body including a housing installed and fixated on a wall or a handrail of a ship and has an accommodation space therein, and a cover combined with the housing to be able to be opened and closed; a ladder unit accommodated in the accommodation space of the housing, and automatically drawn to the outside by having one end connected and fixated on the lower end of the housing; and an operation unit including a horizontal level installed in the housing and recognizes the heel angle of the ship, and a controller which receives a signal of the heel angle value recognized by the horizontal level and judges whether the received heel angle value is over a predetermined target heel angle value. Passengers have difficulties in escaping from a ship when the ship is grounded on the rocks, and the heel angle of the ship is changed by the rapid veering of the ship observed in sinking accidents for a plurality of ships. Accordingly, the ladder is drawn from the ship by making the cover be opened by the horizontal level recognizing the heel angle of the ship to operate an opening member depending on a predetermined target heel angle value, wherein the opened cover tilted downwards have a slope and makes the wheels installed in the lower end of the ladder roll down to extract the ladder folded and stored in the main body. |
