PROBLEM TO BE SOLVED: To suppress vibrations of a cab deck and keep the mass of a support beam light.SOLUTION: A revolving super structure 1 includes a revolving frame 10, an engine deck 20, a cab deck 30, and a second support beam 42. The revolving frame 10 has a front plate 15 for connecting vertical plates 13 facing each other in a lateral direction X. The second support beam 42 is connected to the revolving frame 10 and the cab deck 30. The second support beam 42 is arranged in such a manner as to overlap the front plate 15 in a view from the lateral direction X.SELECTED DRAWING: Figure 1

    【課題】キャブデッキの振動を抑制するとともに支持梁の質量を抑制する。【解決手段】上部旋回体1は、旋回フレーム10と、エンジンデッキ20と、キャブデッキ30と、第二支持梁42と、を備える。旋回フレーム10は、横方向Xに対向する縦板13どうしをつなぐ前板15を有する。第二支持梁42は、旋回フレーム10とキャブデッキ30とにつながれる。第二支持梁42は、横方向Xから見て前板15と重なるように配置される。【選択図】図1
