国指定重要文化財 Japan's National Important Cultural Property 光をまとう佐賀昇降橋The Saga Lift Bridge bathed in light

佐賀にある国指定重要文化財の昇降橋を再度撮影しました。
今回夕陽を浴びる昇降橋や、ライトアップされた昇降橋の姿を撮影しました。
この昇開橋は橋脚と橋脚の間が約２６メートルで、そこに架けられた約２４メートルの可動橋が約２３メートルの高さまで上るようになっていますが今回は夕刻からの撮影で昇降シーンはありません。
昇降シーンは過去掲載した映像にてご覧いただければ幸いです。
このような可動橋は清水港線の巴川鉄橋にもあったそうですが、現在では廃止されています。
昇開橋の主な構造は、鉄塔の高さ約３０メートル、可動橋の自重約４８トン、約２０トンのウェイトが両側の鉄塔に下がっており、さらに、平衡ワイヤにより左右のバランスをとり、強風にも耐える構造となっています。
I filmed another video of the lift bridge, a nationally designated important cultural property in Saga City, Japan.
This time I filmed the lift bridge bathed in the setting sun and when it was lit up.
The distance between the piers of this lift bridge is about 26 meters, and the 24-meter movable bridge that is suspended between them rises to a height of about 23 meters, but this time the filming started in the evening, so there is no lifting or lowering scene.
Please see the video previously posted on this channel to see the lifting and lowering scene.
There was also a similar movable bridge on the Tomoe River Railway Bridge on the Shimizuko Line, but it has since been abolished.
The main structure of the lift bridge is a steel tower about 30 meters high, with the weight of the movable bridge being about 48 tons, and weights of about 20 tons hanging from the steel towers on both sides. In addition, the left and right are balanced by balancing wires, and the structure is designed to withstand strong winds, making it a valuable bridge.
