PROBLEM TO BE SOLVED: To enable the transportation of a revolving frame while suppressing the deflection of a boom in a lateral direction, prevent a standing angle of the boom from being restricted while ensuring excellent visibility from a cab, allow the attachment work of an attachment bracket with ease, and prevent the attachment work of the boom from becoming complicated.SOLUTION: A revolving super structure 16 of a crane comprises a revolving frame 20. The revolving frame 20 comprises a front side frame 21 in which paired attachment brackets 39R, 39L are provided at an interval in a lateral direction. A dimension of the front side frame 21 in a longitudinal direction is smaller than a dimension of the front side frame 21 in the lateral direction. A lower boom 50 comprises a right side divided boom 52 on the side of a cab 30, and a left side divided boom 54 on the opposite side of the cab 30. A width of the right side divided boom 52 in the lateral direction is smaller than that of the left side divided boom 54. An end edge of the right side divided boom 52 on the cab 30 side is disposed on the side of a revolving center O than the cab 30.

    【課題】ブームの左右方向へのたわみを抑制しつつ、旋回フレームの輸送を実施可能にし、キャブからの良好な視界を確保可能にするとともにブームの起立角度が制限されるのを防ぎ、且つ、取付ブラケットの取付作業を容易に行えるようにし、且つ、ブームの取付作業が煩雑になるのを防ぐ。【解決手段】クレーンの上部旋回体16は、旋回フレーム20を備え、旋回フレーム20は、一対の取付ブラケット39R,39Lが左右方向において間隔をあけて設けられる前側フレーム21を有し、前側フレーム21の前後方向の寸法は、前側フレーム21の左右方向の寸法よりも小さく、下部ブーム50は、キャブ30側の右側分割ブーム52と、キャブ30と反対側の左側分割ブーム54とを有し、右側分割ブーム52は、左側分割ブーム54よりも小さい左右方向の幅を有し、右側分割ブーム52のキャブ30側の端縁は、キャブ30よりも旋回中心O側に配置されている。【選択図】図2
