<p>PROBLEM TO BE SOLVED: To provide an embarking-disembarking device capable of holding a slope in a horizontal state or an inclined state near to it even if a height difference between an embarking-disembarking deck and a pier is large, and capable of reducing an installation space of stairs in the pier more than a conventional embarking-disembarking device of changing in an inclination of the stairs.SOLUTION: The embarking-disembarking device comprises a stand arranged in the pier, a slope installing base mounted on an upper part of the stand, a slope for supporting a root part in a cantilever state by the slope installing base, base lifting means provided in the stand and horizontally lifting the slope installing base and expansion stairs for embarking-disembarking an embarking person to the slope installing base and always expanding-contracting at the same inclination on the basis of an upper surface of the slope installing base in response to a height from the ground surface of the slope installing base after lifting by the base lifting means. Thus, even if the height difference between the embarking-disembarking deck and the pier is large, the slope can be held in the horizontal state or the inclined state near to it, and the installation space of the stairs in the pier can be reduced more than the conventional embarking-disembarking device of changing in the inclination of the stairs.</p> |
