To provide a gangway ladder facility with no occurrence of failure such as rusting or occurrence of abnormal sound.SOLUTION: A gangway ladder facility comprises: a gangway ladder device 10 composed of a hull side platform 1 attached to be capable being oscillated between a stored posture standing perpendicular to a deck of a vessel and a horizontally inclined use posture, and a ladder 2 coupled to the hull side platform 1; a davit 4 retaining the gangway ladder 2 to be capable of rotating between the stored posture standing perpendicular to a deck of a vessel and a horizontally laid out use preparation posture; a first support shaft 3 for attaching the hull side platform 1 to the deck to be rotatable; and a second support shaft 5 for attaching the davit 4 to the deck to be rotatable. A swivel joints 20 is installed in between the support shaft 3 and a coupling shaft 6 and a swivel joint 30 is installed in between the support shaft 5 and the coupling shaft 6. Since the swivel joints 20, 30 absorb the slack in the coupling shaft 6, the support shaft 3 on the hull side platform 1 and the support shaft 5 of the davit 4 can be smoothly synchronously rotated, and since the coupling shaft 6 does not come into contact with hardware fixed to the deck, there is no occurrence of rusting and no occurrence of abnormal sound.SELECTED DRAWING: Figure 1
【課題】発錆や異音発生等の不具合が生じない舷梯設備を提供する。【解決手段】船舶の甲板に対して垂直に立った格納姿勢と水平に倒した使用姿勢との間で揺動可能に取付けられた船体側踊り場1と、船体側踊り場1に連結された舷梯2とからなる舷梯装置10と、舷梯2を、船舶の甲板に対して垂直に立った格納姿勢と水平に倒した展開準備位置の間で回転可能に保持するダビット4と、船体側踊り場1を甲板に対し回転可能に取付ける第1の支軸3、およびダビット4を甲板に対し回転可能に取付ける第2の支軸5からなる。支軸3と連結軸6の一端との間に自在継手20が介装され、支軸5と連結軸6の他端との間に自在継手30が介装されている。自在継手20,30が連結軸6の撓みを吸収するので、船体側踊り場1の支軸3とダビット4の支軸5を円滑に同期回転させることができ、連結軸6は甲板に固定した金物とは接触しないので、錆の発生も異音の発生も生じない。【選択図】図1
