<p>PROBLEM TO BE SOLVED: To provide a freight-receiving stage for a building, by which the moving and installing works of the freight-receiving stage can be conducted rapidly. SOLUTION: The freight-receiving stage 10 has a main body 16 formed so as to be made smaller than the opening 14 of the building at the time of a projection onto a horizontal surface and two pairs of sliding means 18, 20 installed to the main body 16 in free contraction-extension manner. The sliding means 18, 20 are formed so that the freight-receiving stage 10 is supported to the sections 21 of the building in the peripheries of the openings 14 of each floor under the state, in which the sliding means 18, 20 are extended, and the freight-receiving stage 10 can be passed into the openings 14 without substantially changing their postures under the state, in which the sliding means 18, 20 are shrunk.</p> |
