PURPOSE: An opening and closing ladder for a ship is provided to facilitate the handling of heavy objects through an opening because the ladder can be partially assembled. CONSTITUTION: An opening and closing ladder for a ship comprises a ladder body(120), first separating members(131), second separating members(132), first connection members(141), second connection members(142), locking parts(150), hinge parts(160). The ladder body has multiple footholds. The first and second separating members are fixed on the wall of a hull adjacent to an opening to separate the ladder body from the wall of the hull. The first and second connection members are coupled to the ladder body. The locking parts are coupled to the first separating members and the first connection members to selectively lock the first separating members and the first connection members. The hinge parts are arranged in the opposite side of the locking parts along a longitudinal direction of the footholds. The hinge parts are installed in the second separating parts and the second connection members to form a rotary shaft of the ladder body. |
