BRIDGING DEVICE
To provide a bridging device or bridging system in which a tip part of a bridging part is prevented from coming off a landing target (i.e., target facility) of an offshore facility even when momentary and irregular rolling occurs due to the influence of ocean waves etc., thereby preventing workers from falling off, and which can be installed on small vessels.SOLUTION: A bridging device 1 has: an oscillation compensation mechanism 3 that is installed on a ship to support a table 4, and controls the inclination of the table 4 with respect to rolling of the ship to keep an angle of the table 4 to a horizontal direction constant; a bridging part 2 whose one end on the table 4 side is axially supported by a pivot part 5 and whose the other end performs inclined movements upward and downward with respect to the table 4 to be hung on a target facility 7; and a bridging part rotation mechanism 6 that is installed on the table 4 and supports the pivot part 5 so that the bridging part can freely rotate around a rotation axis perpendicular to an upper surface of the table.SELECTED DRAWING: Figure 1
【課題】波浪などの影響によって瞬時的で不規則な動揺が生じた場合でも架橋部の先端部が洋上施設の上陸目標（即ち、目標設備）から離脱することを回避して作業員の転落を防止し、かつ、小型船舶にも搭載可能な架橋装置または架橋システムを提供する。【解決手段】架橋装置１は、船舶に設置され、テーブル４を支持するとともに、船舶の動揺に対するテーブル４の傾斜を制御してテーブル４の水平方向に対する角度を一定に保つ動揺補正機構３と、テーブル４側の一端が軸支部５によって軸支持され、他端がテーブル４に対して上向き及び下向きに傾斜動作して目標設備７に掛けられる架橋部２と、テーブル４に設置され、前記架橋部が前記テーブルの上面に対して垂直な回動軸を中心に回動自在となるように軸支部５を支持する架橋部回動機構６と、を有する。【選択図】図１
