DEVICE BY WHICH PEOPLE BOARD AND LEAVE SHIP

摘要

PURPOSE:To effectively absorb upward and downward movement by mounting an intermediate platform so as to freely be turned on a first accommodation ladder whose one end is supported on a deck so as to freely be turned and driven and freely mounting a second accommodation ladder on the other end of this intermediate platform so as to freely be turned. CONSTITUTION:An intermediate platform 2 is mounted so as to freely be turned on one end of a first accommodation ladder 1 whose other end is supported on a deck Z so as to freely be turned. A second accommodation ladder 3 is mounted on the other end of this intermediate platform 2 so as to freely be turned. The first accommodation ladder 1 and the platform 2 are turned freely through a driving device and the intermediate platform 2 and the second accommodation ladder 3 are freely turned. As a result, the upward and downward movement, within the small range, of a ship can be absorbed by the free turning movement between the intermediate platform 2 and the second accommodation ladder 3.
