Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a bridge crane that can be reduced in own weight and improved in stability at the time of occurence of a windstorm and an earthquake.SOLUTION: The bridge crane comprises a lower structure 10 having a plurality of legs 11 and an upper structure 20 supported on an upper end part of the lower structure 10. The upper structure 20 has a boom 22 expanded toward one side more than the lower structure 10, a trolley 23 that is moved along the boom 22 and a spreader 24 that is lifted through the trolley 23. Machine rooms 30A and 30B, in which a derricking device 34 of the boom 22, a first traversing device 31 and a second traversing device 33 of the trolley 23, a hoisting device 32 of the spreader 24 and a control device 35 that controls all devices are installed, are arranged at a lower end part of the lower structure 10.
【課題】自重を軽くすることができると共に、暴風時や地震時の安定度を向上することができる橋形クレーンを提供する。【解決手段】複数の脚11を有する下部構造体10と、下部構造体10の上端部に支持された上部構造体20とを備え、上部構造体20が、下部構造体10よりも一方側に張り出したブーム22と、ブーム22に沿って移動するトロリ23と、トロリ23を介して昇降するスプレッダ24とを有し、ブーム22の起伏装置34と、トロリ23の第一横行装置31、第二横行装置33と、スプレッダ24の巻上装置32と、各装置を制御する制御装置35とを設置する機械室30A、30Bを、下部構造体10の下端部に配置する。【選択図】図1 |
