MOVABLE PIER
PROBLEM TO BE SOLVED: To provide a movable pier excellent in safety capable of restraining a step difference between a bridge girder part and an object of extending the bridge girder part, even when a wave is rough.SOLUTION: A vertical distance (d) is maintained in a predetermined allowable range by changing a vertical position of a substrate 3 by controlling operation of a lifting part 5 by a control part 13 based on detection data by a step difference sensor 14 for detecting the vertical distance (d) between a tip part 4a of a bridge girder part 4 and an upper surface of an object T, and is thereby prevented from becoming excessive in a step difference between the bridge girder part 4 and an upper surface of the object T, so that even when an installation place or the object T of a movable pier 1 vertically rocks, a user H can safely transfer between the object T and the movable pier 1.SELECTED DRAWING: Figure 3
【課題】波が荒い場合であっても、橋桁部と橋桁部が架け渡される対象物との段差を抑制できる安全性に優れた可動式桟橋を提供する。【解決手段】橋桁部４の先端部４ａと対象物Ｔの上面との上下距離ｄを検知する段差センサ１４による検知データに基づいて、制御部１３により昇降部５の動作を制御することで、基板３の上下位置を変化させて上下距離ｄを所定の許容範囲内に維持し、橋桁部４と対象物Ｔの上面との段差が過大になることを防止することで、可動式桟橋１の設置場所あるいは対象物Ｔが上下揺れした場合であっても、対象物Ｔと可動式桟橋１との間を利用者Ｈが安全に乗り移ることを可能にする。【選択図】図３
