The invention relates to the technical field of ship stairs, and in particular relates to an indoor main ladder meeting requirement of ship A-level fireproof deck separation. The indoor main ladder comprises a plurality of layers of decks arranged on a ship and rectangular stair mounting openings formed in each layer of deck, the rectangular stair mounting openings are aligned with one another inthe vertical direction, a straight inclined ladder is obliquely erected between every two vertically adjacent rectangular stair mounting openings, and the arrangement directions of the straight inclined ladders are consistent; a steel back plate is integrally arranged on the back surface of the stairs of the straight inclined ladders; and a retractable cargo transportation device is arranged on the straight inclined ladders. The space occupied by the ship main ladder is reduced, and meanwhile, the main ladder is convenient to install.
