REVOLVING FRAME FOR CONSTRUCTION MACHINE
To provide a revolving frame having higher rigidity than before.SOLUTION: A revolving frame 4 of a construction machine 1 has a first horizontal plate 16 extending in the width direction, a first vertical plate 18 extending in the fore-and-aft direction and having its rear end fixed to a widthwise midpoint of the first horizontal plate, a second vertical plate 19 extending in the fore-and-aft direction and having its fore-and-aft midpoint fixed to the right end of the first horizontal plate, a third vertical plate 20 extending in the fore-and-aft direction and having its fore-and-aft midpoint fixed to the left end of the first horizontal plate, and a second beam 26 extending in the width direction and having its widthwise midpoint fixed to the front end of the third vertical plate 20 and having its right end fixed to the fore-and-aft midpoint of the first vertical plate 18.SELECTED DRAWING: Figure 2
【課題】従来よりも剛性が高められた旋回フレームを提供する。【解決手段】建設機械１の旋回フレーム４は、幅方向に延びる第１横板１６と、前後方向に延び、かつ、後端部が第１横板における幅方向中途部に固定された第１縦板１８と、前後方向に延び、かつ、前後方向中途部が第１横板の右端部に固定された第２縦板１９と、前後方向に延び、かつ、前後方向中途部が第１横板の左端部に固定された第３縦板２０と、幅方向に延び、かつ、幅方向中途部が第３縦板２０の前端部に固定されるとともに、右端部が第１縦板１８における前後方向中途部に固定された第２ビーム２６と、を有している。【選択図】図２
